Amulet of Judgement

This amulet has 3 charges. While wearing it, before you make a melee attack roll, you can expend one charge. If that attack hits, the target takes an additional 3d8 radiant damage. If that attack misses, you take 3d8 necrotic damage. 

The amulet regains 1d4 charges each day at dawn. If you expend the amulet's last charge, roll a d20. On a 1, the amulet crumbles into ashes and is destroyed.
