Basically I was thinking about giving helmets a +1 AC to players. Now I know its’ basically allowing players to get plus 1 AC for like 10-20 gp so here are some draw backs that I think would make the player really think twice. A guaranteed one is basically anyone who wears one gains a point of exhaustion for every 3 hours of continued use without taking it off for at least a few minutes. This doesn’t apply when the character is sleeping during short or long rests.
1: -3 to -5 on Perception rolls of any kind. (can be modified for type of helmet)
2: -3 to investigation of any kind
3: and finally, very susceptible to flanking maneuvers in combat
I was thinking of applying 1 or 2 appropriately to the type of helmet they wear. Only way all 3 would apply is if I decide the helmet gives +2.
Main reason is because my players like to look cool wearing the helmets but wanted some function to them as well. Is this a viable option?
