The description of the signifier mask is a little weird.
Spoiler:Upon initiation, a Hellknight signifer receives a mask, often devoid of eyeholes or other personal features. This mask doesn't obscure the signifer's vision, and while wearing it he gains a +2 competence bonus on Sense Motive checks and on saving throws against spells and abilities that rely on visual effects. A Hellknight signifer with a bonded object from the arcane bond class feature can perform a special ritual that costs 500 gp and takes 8 hours to complete. This ritual converts the signifer's mask into his new bonded item, which takes up the head slot.
So if one does not elect to make it a bonded item, what slot does it take up? Or does it not take up a slot, since it's a class feature rather than a magical item?
