BeckyI dunno, if I was an assassin I think I would want a dagger that causes death at least moderately frequently.
JTO is Typing@mezz Doesn't say whose death, this could be the hitman equivalent of pharmaceutical warnings. May sometimes maim or kill the user, consult your fantasy physician.
@JTO_is_Typing other side effects include: loss of fingers, acute pain, blindness. Only use as prescribed by your cleric.
