The Sacred Star

The Sacred Star is a very rare +2 Morningstar that applies  Radiating Orb on hit and possibly turns the target if it is Undead. It also grants the Dawnburst Strike weapon action.

The power of this item lies in belief, though not in any god. This item believes that it's very good at hitting things, so it is. Belief is quite powerful when it comes to violence.

Damage from  Tenacity still applies Radiant Strike and Sanctified Weapon's effects.^[verify]

Regarding Radiant Strike:

Radiant Strike works only for the weapon with the passive feature

Regarding Tenacity:

If a weapon action misses, using Tenacity does not trigger its effects.
As Tenacity deals weapon damage even if an attack misses, it can trigger many on-hit effects from equipment. For example, from the  Gloves of Power, the  Callous Glow Ring, weapon coatings, or any infusion from the  Ring of Elemental Infusion.

Regarding Tenacity:

As  Horde Breaker (Melee) rolls invisible, zero-damage weapon attacks against all enemies in the Horde Breaker area of effect, Tenacity can be prompted to trigger against them even if the first attack hits. It is therefore possible to score 2 hits in one attack: the full attack against the original Horde Breaker target and a Tenacity hit against another target.

Regarding Dawnburst Strike:

The description in-game notes an incorrect  DC 13 Constitution Saving Throw save. It requires a weapon action save with a +2 DC bonus.
Despite the in-game description stating only enemies in the light must save against becoming blinded, the blindness affects all creatures in the area, even allies.
- Due to a coding error, blindness does not affect the original target of the attack.
The additional ⁠Radiant damage is treated as a separate damage rider source even in Honour Mode.
