Demon Armor
Aura strong necromancy [evil]; CL 13th
Slot armor; Price 52,260 gp; Weight 50 lbs.
Description
This plate armor is fashioned to make the wearer appear to be a demon. The helmet is shaped to look like a horned demon head, and its wearer looks out of the open, tooth-filled mouth. This +4 full plate allows the wearer to make claw attacks that deal 1d10 points of damage, strike as +1 weapons, and afflict the target as if she had been struck by a contagion spell (Fortitude DC 14 negates). Use of contagion requires a normal melee attack with the claws. The “claws” are built into the armor's vambraces and gauntlets, and cannot be disarmed.
A suit of demon armor is infused with evil, and as a result it bestows one negative level on any nonevil creature wearing it. This negative level persists as long as the armor is worn and disappears when the armor is removed. The negative level cannot be overcome in any way (including restoration spells) while the armor is worn.
