So I got an idea, a new feature for a mod where vampires take 35 fire damage per second while in the sun, and protects against that... Changing it to 1 fire damage per second, and giving you 50 less maximum stamina and magicka.

The idea, is to encourage very tactical type of use- it would allow you to survive long enough, to do things like talk to merchants, maybe even do a few quests that require journeying into the sun- if you have enough HP, and maybe take some health potions/blood potions and use health drain spells/heal between interior cells on the way to a destination stratagetically- the mod also makes restoration spells nearly impossible to cast... But you would be much weaker than a vanilla Skyrim vampire in sunlight, and because of you wearing the mask it would also lower your speechcraft, and make merchants rip you off more, because people would of course find you untrustworthy for hiding under it.

The lesser sunlight damage, and stamina/magicka debuff I believe I can figure out on my own, but... How... How would I make a helmet able to disguise a stage 4 vampire when worn???? Can someone please tell me if this is possible or how?

(I hope it can be done without altering vanilla stuff).
