Yeah i ment headpiece for poison resistance, just mixed it up. Sorry.

Its acutally quite strange that legs only give the fire damage debuff.. and no bonuses.
would be really fun to know if the "weakness" stacks (for example 3x + 3x + 3x = 9x more fire damage taken) because 3 items in set.

Or if the extra damage taken is the same even though someone only uses 1 piece of the set.
