Problem:

Some characters just aren't blessed with good looks. Being berated by your colleagues during a dungeon can sap the will of even the most confident of paladins. There are times when life just feels to much.

The answer to this problem should be a fully face concealing helmet. Sadly this excludes the use of many good helmet options.

Suggested solution:

Cosmetic helmet mob that changes your current helmet to look like a paper bag has been shoved firmly over the character's head. Now people can wear those wise tiara's of inner focus without having to expose their looks to ridicule.

As a store purchase item this obviously would need to have some token stat benefits. How about something along the line of:

+1 morale bonus to all skills and saves
+2 security bonus to diplomacy
1x per day clicky "Take the bag off" - petrifying attack vs anyone who can see the caster. low DC to avoid being OP.
