Undead Slayer’s Hammer

Weapon (two-handed hammer), very rare (requires attunement by cleric or paladin)

This hammer is decorated with symbols of a life or light-oriented deity. It is a massive hammer with an iron grip.

The wielder gains a +1 bonus to attack and damage rolls. Undead creatures struck by it take an additional 1d12 radiant damage. If an undead target has 25 hit points or fewer after taking this damage, it must succeed on a DC 15 Wisdom saving throw or become frightened of you until the end of your next turn.

This hammer has 5 charges. While holding it, you can use an action to expend 1 or more of its charges to cast cure wounds (1 charge per spell level, up to 5th) or to use Channel Divinity (3 charges).

The hammer regains 1d4+1 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the hammer vanishes in a flash of light. In due time it will find a new owner.
