Armored Collar (3.5e Equipment)

Armored Collar
The armored collar is not armor in and of itself, but rather an armor add on which stacks the AC bonus with other armors. Worn on the neck, it provides a +1 additional AC bonus, and has a 50% chance of preventing any attempt to behead the user (such as from a vorpal sword). However, vision is obscured as the collar partly covers the face, giving a -4 penalty on Spot checks. The material of the armored collar is typically re-enforced leathers with a metal skeleton, but solid metal versions exist for an extra +20 gp.

The AC bonus does not stack with other armor add ons like the dastanaOA. It counts as light armor for the purpose of proficiency.
