List of bugged passives

This list aims to catalogue passives which do not function as would be expected based on their tooltips, or which have other problems - or missing information - in their description, function, or location. This list is unlikely to be comprehensive as it is likely there are many issues with passives of which we are unaware.

As this list deals with problems that have a high likelihood of being changed in patches and hotfixes, it is likely that entries will be incorrect following an update.

All entries are currently correct as of Hotfix 33.

Passives

More...

Name	Bugs
Ablaze	This ability always uses the caster's Wisdom to determine the spellcasting DC, regardless of the summoner's actual spellcasting ability.
Absolute's Bane	The Bane effect does not activate when the wearer is  disguised, even if it is noted in the passive effect UI. The Bane effect's saving throw does not appear in the combat log, nor do reactions like  Portent Dice trigger, even though the passive effect UI indicates there is a saving throw, and the effect sometimes does not trigger (presumably because the enemy succeeded at their saving throw).
Actor	The ability score increase can increase Charisma beyond the stated maximum of 20.
Adrenaline Rush	The in-game tooltip stating that Adrenaline Rush grants 2 turns of Wrath is incorrect, it actually grants 3 turns of the condition. The in-game tooltip states that Adrenaline Rush is once per turn. It is not.
Arcane Battery	The "Long Rest" cooldown restriction is per character, rather than per item. As such, this passive can be used repeatedly by passing the weapon possessing this feature to different characters, activating it once on each. The effect of this passive is consumed if active when the character casts a cantrip, despite the cantrip not being highlighted in the character's cast bar.
Arcane Echomalefaction	Due to a hidden condition which gets applied when a ranged weapon attack misses, this passive effect applies even though it appears it should not.
Arcane Ward	Despite being an Abjuration spell and consuming a spell slot,  Shield does not grant Arcane Ward charges.  Counterspell will always restore 3 charges, even if upcasted. Using  Metamagic: Extended Spell to cast any Abjuration spell with a limited duration might lead to Arcane Wards be overstacked up to 4x Abjuration Wizard level; this happens as the Arcane Ward duration is doubled by Extended Spell after the 2x Wizard level capping. That means extend spells like  Sanctuary,  Arcane Lock and  Banishment can be explored for off or mid-combat situations. Ex. a Sorcerer 2 / Abjuration Wizard 5 with 7 charges of Arcane Ward casting Extended Banishment will end up (capped) with 20 charges. A Sorcerer 2 / Abjuration Wizard 6 in the same situation would end up with 22 charges. When overstacking Arcane Wards, casting any Abjuration spell (except  Shield) will enforce the Arcane Wards to be capped again at 2x Abjuration Wizard level.  Glyph of Warding: Sleep 2-turn effect duration does not count as a spell with limited duration as the warding trap has no duration limit, despite the tooltip describing it as a 4-turn duration. When an Abjuration School Wizard has zero Arcane Ward charges, many actions/abilities will restore as many charges as character's Wizard level as seen on this Reddit post. Some examples: Casting some spells, e.g.  Booming Blade,  True Strike,  Fire Shield, or  Hex. Equipping some equipment applying conditions, e.g. Shar's Spear of Evening or Nyrulna - including automatically requipping these weapons after throwing them. Receiving some conditions, e.g.  Lightning Charges,  Force Conduit,  Heat, or  Arcane Acuity. Some class abilities, e.g. Barbarian's  Rage, Eldritch Knight's  War Magic, or War Cleric's  War Priest. If an attack roll of the Abjuration Wizard is blocked by a target casting the Wizard version of  Shield, the Abjuration Wizard attacker will lose all their Arcane Ward charges.
Arming Enhancement	The +2 bonus to attack rolls also affects spell attacks, unarmed attacks, and throw attacks; however, except for throw attacks involving weapons with the Thrown property, those attacks do not receive the +2 damage.
Artificial Sight	The Artificial Sight effect does not provide the cone of light that you'd otherwise get by obtaining the Darkvision effect from a different source, such as from a spell or from having the passive innately through race. It also allows the wearer to see through magical darkness, despite not stating such in the description.
Aspect of the Beast: Stallion	If you have any remaining temporary hit points from a previous activation of this feature, Dashing will not replenish them back to twice your Barbarian level. You can only gain the temporary hit points again once you've lost all of them.
Blessed Healer	(As of Hotfix #11, possible Bug) Blessed Healer seems to activate on much more sources of Healing than the tooltip indicates: Healing Spells of Level 1 and higher that target only the user will trigger both  Disciple of Life and Blessed Healer (for a total of 4 + 2 * Spell Level). Healing magic that does not have a level (such as the Channel Divinity  Preserve Life, the cantrip  Selûne's Dream and the Paladin class action  Lay on Hands) is treated as level 0, and the caster restores 2 HP to themselves. Healing potions (of all strengths) are treated as level 1 (whether consumed or thrown), and the caster restores an additional 3 HP to themselves.
Blind Immunity	Despite not stating such in the description, Blind Immunity also allows the wearer to see through magical darkness.
Blood-Curdling Emission	The combat log erroneously states the spell save DC of the wielder; it still uses the fixed DC of 12.
Bolstering Smite	The temporary hit points only have a StackPriority of 1, and as such are overridden by any other source of temporary hit points that have a StackPriority of 1 or higher, even if the new source is of a lesser value.
Breezeswift Speed	Breezeswift Speed is only removed when making a weapon attack, as opposed to the next attack roll.
Callous Glow	The ingame tooltip does not specify the damage type, but it is Radiant.
Caustic Strikes	This feature triggers even on a miss, dealing damage and potentially  Paralysing the target.
Chilling Counter	The in-game description says there is a DC 13 saving throw, but in fact there is no saving throw to avoid the effect. Chilled will be applied on every single missed attack.
Coldbrim Chill	Due to a hidden condition that gets applied when a ranged weapon attack misses, this passive effect applies even though it appears it should not.
Companion's Bond	The in-game description says that the bonus scales with "your" (i.e. the Beast Master's) proficiency bonus, but in fact it uses the companion's proficiency bonus. This means the bonus will not increase to +4 until the final level 11 upgrade to your animal companion rather than at character level 9. Prior to the level 5 upgrade, animal companions will incorrectly have a proficiency bonus of 0 instead of +2. After the level 5 upgrade, the proficiency bonus will correctly increase to +3. Effectively, this means that at level 5, your animal companions will also receive an increase to their attack rolls equal to their proficiency bonus, but this is not actually part of this feature, merely a consequence of bugged proficiency bonus progression.
Consumed Shadow Weave	The granted Level 3 Shadow Spell Slot is not reset when consuming a Potion of Angelic Slumber nor when affected by  Divine Intervention: Opulent Revival.
Damp Aegis	The description on Water Layer Protection incorrectly uses the same description as  Wet, despite the two conditions having different effects.
Dark One's Blessing	The temporary hit points lack a StackPriority and as such are overridden by any other source of temporary hit points, even if the new source is of a lesser value such as from Well-Liked and Well-Fortified.
Dolor Amarus	Despite the description, the passive Dolor Amarus does not deal an additional 7 damage on unarmed attack critical hits (includes Throw attacks).
Dread Ambusher	The increased movement distance is tied to the extra weapon attack. Once the extra attack has been made, any unused bonus movement is immediately lost.
Dreadful Hewer	Although the tooltip mentions Disadvantage for  Fear Saving Throws specifically, this shield inflicts Disadvantage for  Frightened Saving Throws, such as from  Dissonant Whispers. Inspecting the tooltip in-game leads to the Frightened condition, not  Fearful.
Duergar Resilience	Only two spells in the entire game are affected by this passive's Advantage on Saving throws against Paralysed:  Paralysing Ray  Ocular Nightmare
Effective Transmitter	It does not work against Animated Armours, Bernard and Githyankis in Crèche Y'llek, even though  Shocking Grasp has Advantage against them.
Eight Legged Waltz	This passive has no effect at all.
Eldritch Strike	Despite the description stating it affects the "next spell", this condition affects all saving throws caused by the Eldritch Knight until it expires. This applies also to non-spell sources such as weapon actions, weapon passives like Blood-Curdling Emission, illithid powers, etc.
Ever Vigilant	Unlike other temporary hit points, the temporary HP granted by Ever Vigilant disappears at the end of combat. This functionality is not stated in the description.
Executioner	Despite the tooltip suggesting otherwise, Executioner only applies to the next weapon attack roll made.
Expert Divination	Prophecy: Delivering Alms cannot be completed because it references a passive that does not exist in the game code.
Fancy Footwork	Enemies with the  War Caster or  Polearm Master feats still take Opportunity Attacks when otherwise affected by this feature.
Favourable Beginnings	Contrary to the description, only Deception and Persuasion receive ability check bonuses.
Fiendish Fire	The Fiendish Fire saving throw appears every time the wielder causes a damaging effect including spells and melee attacks, but the effect itself is not actually applied, even if the target fails the saving throw, unless the damage is dealt by this weapon.
Fiery Return	When triggering Fiery Return with a  Bonus Action (for example with  Metamagic: Quickened Spell), the extra bonus action will be consumed immediately.
First Blood	Does not work on Honour mode
Freecast	When fast traveling between areas that require a loading screen (such as between Act 1 and Act 2, or between the Lower City and Rivington), Freecast and many other abilities have their cooldowns reset. This allows for multiple Freecast uses in a day, which can be quite useful for buffs or summons requiring high level spell slots such as  Heroes' Feast,  Planar Ally, and more. Freecast can be easily reset by having another character apply a condition (such as  Guidance or  Aura of Protection) on the character seeking to (re)use Freecast.
Fury In The Marrow	Hostile creatures making a successful Wisdom saving throw receive no damage instead of half damage.
Godswill	Contrary to the description, the extra Channel Divinity charge actually comes back after a short rest.
Grievous Retribution	The in-game tooltip stating that the effect grants 1 turn of Wrath is incorrect, it actually grants 2 turns of the condition.
Heart of the Storm	Despite its tooltip stating otherwise, Heart of the Storm also activates on cantrips.
Illithid Persuasion	A bug may occur where one may receive the "True Soul" tag early - on the 4th use.
Immutable Form	This effect protects against specifically  Banishment when cast at level 4 and  Arcane Shot: Banishing Arrow. Any other source of  Banished such as  Banishing Smite or upcasted  Banishment will not be affected.
Infernal Acuity	The Infernal Acuity passive grants the wearer +1 all attack rolls.
Infernal Sight	Infernal Sight does not see through magical darkness; it only grants immunity to  Blinded and does not provide the cone of light that you would otherwise get by obtaining the Darkvision effect from a different source, such as from a spell or from having the passive innately through race.
Infernal Weapon	The roll for the  Poisoned saving throw is not shown in the combat log for either a successful or failed save. Because it has a low DC 12  Constitution saving throw, this can give the impression that the poison effect does not work at all.
Infested	Due to a coding error, Infested displays a saving throw made by the ettercap in the combat log when attacked.
Ironvine	Ironvine activates on any attack, not just melee attacks.
Legendary Action: Beguiling Rebuke	Beguiled lacks the proper Charmed status group, and as such will not be removed or prevented by typical means.
Legendary Action: Ocular Nightmare	Paranoid Dream increases if the Spectator is targeted with  Mage Armour cast by one of the formerly petrified Drow.
Lesser Infernal Retribution	The required saving throw for Lesser Infernal Retribution is attributed in the combat log to the wearer of the armour, rather than the attacker, but is correctly rolled by the attacker.
Life Essence Harvest	The effect of this passive is consumed if active when the character casts a cantrip from the Necromancy school, despite the cantrip not being highlighted in the character's cast bar.
Life Stealing Critical	The temporary hit points only have a StackPriority of 1, and as such are overridden by any other source of temporary hit points that have a StackPriority of 1 or higher, even if the new source is of a lesser value.
Luck of the Far Realms	Due to the way this passive's reaction is coded'"`UNIQ--ref-00000008-QINU`"', it triggers on attacks that are not natural 20 rolls but are already critical hits due to Critical Hit Threshold Reductions. Luck of the Far Realms is not reset when consuming a Potion of Angelic Slumber nor when affected by  Divine Intervention: Opulent Revival.
Lucky	Lucky grants a toggleable passive by the same name which, when toggled on, provides Advantage on the character's next Ability Check. Due to the way this passive is granted, it defaults to "off" and cannot be toggled "on" the very first time it is acquired until after the character has first made an ability check, has used a reaction, has used a short rest, or has used a long rest.
Magic Initiate: Cleric	This feat has an unlisted effect that increases the maximum AC bonus from Dexterity while wearing Medium Armour from +2 to +3. This effect is equivalent to the Medium Armour Master feat. Also like that feat, this effect will break the Exotic Material feature of certain Medium Armours.
Magic Initiate: Sorcerer	When provided by this feat,  Shield uses spell slots like an ordinary spell without a once-per-long-rest restriction. However this also means that it cannot be used at all by a character with no spell slots.
Magic Initiate: Wizard	When provided by this feat,  Shield uses spell slots like an ordinary spell without a once-per-long-rest restriction. However this also means that it cannot be used at all by a character with no spell slots.
Metamagic: Twinned Spell	Due to the lack of a TargetRadius check for projectile spells, Twinned Spell is compatible with the ranged version of certain spells while also being incompatible with the melee version. An example of this is  Ensnaring Strike.
Monsterslayer	The Monsterslayer passive effect granted by this item adds 1d4 to attack rolls in addition to the damage rolls listed. This passive also applies to ranged attacks while this weapon is equipped, adding 1d4 to attack and damage for them. Spells cast while this weapon is equipped will gain 1d4 to their attack roll but their damage is not increased.
Mystra's Blessing	The in-game description of this passive feature is not entirely correct, and reads as follows: Bless grants an additional 1d4 to Saving Throws and Weapon Attack Rolls, and an additional 2d4 to Spell Attack Rolls. Instead, creatures Blessed with the Staff of Arcane Blessing gain two separate conditions: The regular Bless condition, which grants a 1d4 bonus to all saving throws and attack rolls. The special Mystra's Blessing condition, which grants another 1d4 bonus, but only to spell attack rolls. Specifically, it is possible to lose the regular Bless condition (due to the caster losing concentration) while retaining the Mystra's Blessing condition. In this case, the creature is left with a 1d4 bonus to spell attack rolls, but loses the other 1d4 bonuses, despite the tooltip of the condition claiming otherwise.
Polearm Master: Opportunity Attack	This feature is still able to attack targets that have either  Panache or  Fancy Footwork.
Portent	Portent does not trigger in the following situations: An ally's attack misses due to rolling a natural 1 but the (modified) roll meets or exceeds the target's AC An ally's attack misses and the Portent roll, if used, would be under the target's AC yet would critically hit due to an expanded critical threshold (for Portent Dice below 20) An enemy critically hits but the roll is under the target's AC An enemy save succeeds due to  Legendary Resistance An enemy or ally saves against  Staggering,  Thunderous or  Wrathful Smite or  Topple the Big Folk Portent sometimes triggers unnecessarily due to misinterpreting critical hits or misses as non-critical, or wrongly assuming Portent Dice of 1 or 20 automatically fail or succeed a saving throw.
Rakish Audacity	The description regarding Sneak Attack is incorrect. See  Rakish Sneak Attack (Melee) /  Rakish Sneak Attack (Ranged) for additional information.
Raven Sight	This effect does not provide immunity to all forms of Blindness, but rather only to  Blinded and Blinded from  Darkness.
Rebuke of the Mighty	The description of this passive states it requires a Dexterity saving throw. This is incorrect, as it requires a Strength saving throw.
Reliable Talent	For unknown reasons, Reliable Talent is known to fail when rolling a religion check for the Mirror of Loss, failing to function for every other character or so.
Revenant Scourge	The effects from this passive currently do not function.
Ruintamer Heart	Ruintamer Heart has no effect, and does not function in-game.
Rupturing	The in-game description says the target has a DC 13  Constitution saving throw to avoid the Ruptured effect. However, this is not true and the condition will always be applied.
Scourge of Pests	The in-game tooltip for this passive says it grants bonus damage against insects, but instead it works against myconids.
Sculpt Spells	Despite being an AoE Evocation spell, this ability doesn't work with  Moonbeam.
Sentinel: Snare	Though this applies to druids in Wild Shape and does deal damage, the Damage Roll is empty/bugged as of Hotfix 19.
Shadow Blade	Prior to Patch 8 Hotfix 1, this effect granted advantage to all attack rolls when active. This was changed to require any melee weapon attack.
Shadow-Blinding	In Honour mode, this feature is non-functional.
Shapeshifter Slayer	The Shapeshifter Slayer passive effect granted by this item adds 1d4 to attack rolls in addition to the damage rolls listed. This passive also applies to ranged attacks while this weapon is equipped, adding 1d4 to attack and damage for them. Spells cast while this weapon is equipped will gain 1d4 to their attack roll but their damage is not increased.
Shar's Protection	Even though this passive feature is not listed in the Dark Justiciar Half-Plate (Rare), casting Shar's Aegis with the aforementioned item equipped will still apply  Sharran Retribution to the wearer.
Shield Bash	The description of this passive states it requires a Dexterity saving throw. This is incorrect, as it requires a Strength saving throw.
Shocking Sting	The in-game tooltip for this effect says it has chance to apply  Shocked, but the condition actually applied is the similar but less potent  Shocking Grasp.
Slabjaw Determination	The temporary hit points only have a StackPriority of 1, and as such are overridden by any other source of temporary hit points that have a StackPriority of 1 or higher, even if the new source is of a lesser value.
Slayer's Extra Attack	The in-game description for this passive is copied from  Slayer's Improved Extra Attack and states that it grants two additional attacks, but it actually only grants one.
Slow Fall	Slow Fall toggles off upon losing a  Reaction for any reason and the toggle button is disabled while a reaction is unavailable. If Slow Fall triggers in real-time mode, it does not consume a reaction and therefore does not toggle off at that moment, but it nonetheless does not trigger again until retoggled.
Slow: Casting	This passive is non-functional and hence the  Slowed condition does not affect spellcasting in the way that is described.
Soul Catching	Soul Catching has numerous errors: It states it requires an "unarmed hit" while the  Grasp Essence condition states "hit a creature with an unarmed attack". Functionally, any damaging unarmed attack will trigger the effect, even against world items. It states the wielder regains 10hit points, but instead it grants an ability that when used provides the healing. It states the wielder may gain Advantage on Attack Rolls and Saving Throws until the end of their next turn, while the Grasp Essence condition states the wielder may gain Advantage on Attack Rolls or Saving Throws before the end of their next turn. Advantage is not actually gained, but rather an Interrupt is granted that provides the wielder with a choice of either adding a +5 bonus to a single attack roll or to a single saving throw, at which time the Grasp Essence condition is removed. Due to a coding error, Grasp Essence will be removed from the wielder if it takes damage and does not have any temporary HP.
Spellmight	The Spellmight passive will add its damage bonus to any melee weapon attack that counts as a spell (all smite spells except Divine Smite) yet not apply the -5 to hit penalty.
Stirring Execution	The temporary hit points are actually based on the Charisma modifiers of the characters receiving them, not the character delivering the killing blow with this sword. The minimum of 1 still applies. The temporary hit points only have a StackPriority of 1, and as such are overridden by any other source of temporary hit points which have a StackPriority of 1 or higher, even if the new source is of a lesser value.
Swathed in Shadow	Swathed in Shadow passively adds its Saving Throw bonus at all times, not just when attacked.
Synergetic Moments	Due to a hidden condition that gets applied when a ranged weapon attack misses, this passive effect will apply even though it appears it should not.
Tavern Brawler	Characters with negative strength modifiers (and  Wild Shapes with the same, such as Wild Shape: Cat) have twice reduced attack and damage rolls from this passive. As of Patch 8, bonus damage from this feat bypasses  Sturdy and similar conditions, but only when thrown. As of Patch 8, this feat applies to the damage of several spells and effects while the caster is  Wild Shaped, including but not necessarily limited to:  Moonbeam,  Spike Growth, Noxious Fumes, and even the caster of a  Warding Bond (with no damage type, so resistances do not apply but items with a subtraction from all damage do). Wild Shapes with low  Strength have a penalty applied to the damage roll of these associated spells or effects.
The Pain Maiden's Blessing	The description erroneously claims that the effect lasts until the end of next turn, but instead it is removed at the start of it.
The Scourge Mistress' Bane	While the item description says 'chance,' the chance to inflict  Bane on hit is 100%.
Thunderbolt Strike	Creatures pushed off of ledges by this feature do not suffer fall damage unless the triggering action has an innate push effect like  Thunderwave. The push from this feature does not combine with any push from the triggering action itself. In fact, Thunderbolt Strike may even reduce the push distance since its push effect takes priority. For example,  Thunderwave normally pushes targets 8 m / 27 ft, but this feature reduces this distance to 3 m / 10 ft.
Thunderous Conversion	Though stated "upon the target(s)", Thunderous Conversion can only trigger once per attack. This means that AoE spells (e.g.  Radiance of the Dawn or  Flame Strike) can only apply  Reverberation to the first target in the log order, leaving the rest without the effect. This also means that dealing multiple instances of damage in a single attack (e.g. with  Lightning Arrow) will still only apply 2 turns of  Reverberation.
Titan Weapon	Titan Weapon has an extra description that states "The weapon only adds the modifier if it improves your chance to hit." but this has no actual function/relevance.
Uncanny Dodge	As of Patch 8, Uncanny Dodge has several bugs related to reaction mechanics. It requires the defender to have reaction (resource) available, but doesn't actually consume it when used. It consumes the attacker's reaction (resource) when triggered. It can trigger multiple times in the same turn if hit by different attackers. It can trigger while under conditions that should prevent reaction, such as  Slowed (Condition).
Undead Bane	Despite the description, this passive provides Advantage to all attacks rolls made against Undead targets.
Undead Ward	Though it is not stated in the tooltip, Undead Ward applies to summons with the Fiend classification, as in the case of Shovel, Cambion (Planar Ally), and Conjured Imp.
Unwavering	Unwavering does not prevent movement speed reduction from all Difficult Terrain types, only:  Difficult Terrain,  Lava,  Mud,  Plant Growth,  Twisting Vines, and  Web.
