Breath masks inside normal masks

[Nihisohel]

Some masks like the Plague Mask actually have O2 in em.
I don't see any problem with clown becoming and O2 breathing clown.

the argument as to why clowns cant have an O2 clown mask is that its meant to be a punishment role, or rather to have the player be punished while playing as one
its why clown shoes get slips as well anyway

would be nice if space helmets acted as an O2 mask though
