Perk help: Sizzle and Catch Fire, and weaker in rain

[Boot]

It's me again :/ I'm not too good at modding but I have so many ideas...
This time, I need to add a "perk" when the character gets too hot. Essentially the character will sizzle and then set on a short fire like bushes do in summer. Except the fire will stop after a few seconds like when you step on the lava pools. The threshold would be when the character starts to overheat (when the HUD gets all red and hot and HP loss)
Any help?

I also need a perk to decrease attack damage when wet, and to increase sanity drain when wet
