You've been inflicted with a curse...when things go wrong for you, forces beyond your control attempt to destroy you.
If you would fail any check (including attack rolls, skill checks, and so on) by 10 or more you are set on fire. If you are set on fire in this manner and take damage from it you receive a bonus 1 TP during the TP Vote.
If you are immune to fire you cannot select this trait, and if you become immune to fire while possessing this trait you remove the trait and can pick a new one. Temporary immunity does not remove the trait, only permanent immunity.
