Blade of Sheol (5e Equipment)
From D&D Wiki
Weapon (any sword), rare (requires attunement)
A blade of this power can only be used by someone whose true intent is to wreak havoc on the souls of mortals. This sword, with a blade of onyx and hilt of ivory, devours the very lives of those it slays — giving its wielder license to use said forces for his or her own deed.
When this magic weapon is found it has no charges, and can have a maximum of 8. Delivering a killing blow to a creature that is not a construct or undead with at least an Intelligence score of 3 adds one charge to this weapon. As an action, you can expend 5 charges to cast the spirit guardians spell as if you were of evil alignment. Also as an action, you can expend 8 charges to cast the death ward spell on yourself.
