Description
These weapons are simple, so as not to betray their sinister origins. Their blades are simple steel, and the hilt is leather-wrapped bone. The tang of the dagger is covered in abyssal script and the bone is human.

The demon death dagger is a +1 wounding dagger. But once—just once—between every full moon when it strikes, it can use the spilling blood to open a portal to the Abyss. The wound caused by this blow imflicts 1d4 bleed damage, and requires either a DC 25 Heal check, or a cure spell cast with a caster level check DC 18, to stop the bleeding. Each round the bleed happens, a dretch demon is summoned. The demons last for 2d4 rounds after the victim dies. They rarely move to hasten the victim’s death, but will interfere with anyone trying to aid the victim.
