Description/Exam

You see nothing special.

Notes

• When worn by half-orc or half-troll Vampires, it automatically drops and sacrifices itself. It is not known whether this applies to other races/classes.

Mental shock overcomes you as horrid visions of death and
slaughter appear out of nowhere.  You can not bear to witness
this any longer and must drop this cursed slayer.
You cringe in terror.
You drop A blood-covered cleaver.
Vl'aresch gives you one gold coin for your sacrifice of A blood-covered cleaver.

• It seems likely that the weapon cannot be worn, but does something when worn somewhere.
