Arcane Echomalefaction

Arcane Echomalefaction is a passive feature which applies Reverberation on enemies after applying a condition.

Description

When the wearer inflicts a condition upon a hostile creature, they also inflict 2 turns of  Reverberation.^{[See: Bugs]}

Condition: Reverberation

 Reverberation

Duration: 2 turns

• Affected entity has a -1 penalty to Strength, Dexterity, and Constitution  Saving Throws per remaining turn.

• When the entity has 5 or more turns of Reverberation, it takes 1d4⁠⁠ThunderDRS damage and must succeed a  DC 10 Constitution Saving Throw or fall  Prone. The condition is removed afterward.

• Creatures Immune to ⁠Thunder damage can't receive Reverberation.

How to learn

Granted by the equipment:

• Boots of Stormy Clamour

Notes

• Arcane Echomalefaction triggers only once for any action or effect which inflicts a condition and affects only one target per trigger. If an action applies a condition to multiple targets simultaneously or sequentially (such as the persistent  Blinded aura from  Lathander's Light), the effect triggers only on the first target to receive the condition, even if additional targets become affected later in the turn.
• Applying  Reverberation does not trigger this passive.

Bugs

• Arcane Echomalefaction triggers under many circumstances where it appears it should not, due to hidden technical conditions, such as when a ranged weapon attack misses, when  Sanctuary is cast near enemies, or when revealing an invisible enemy with  See Invisibility.
