Just as planned.
Ghoul Leather.
This special material (which may or may not be made from actual ghouls) can be used to make non metal armor, such as padded and leather armors. A shiny black leather, it reeks of despair and hopelessness. The wearer of armor made of this armor gets a -1 penalty versus fear, but gains a +2 bonus to intimidate and bluff checks made to seduce.
Armor made of Ghoul Leather is always considered masterwork, and costs an additional 1,500 gp.
