You can get multiple, but they all reduce your maximum HP. Anyway, I'm not really worried about it, since it gets eaten up by any damage source. Much less effective against multihit guns, things like Skyburn, etc.

While that much is true, and things like Raging Flame would punch right through it, the cost is so minimal that it almost doesn't matter. Like, I don't think it'll be OVERPOWERED, mind, just that speaking from an 'optimal play' standpoint there's no reason to NOT take it since unless you take less than 24 damage on your first hit (and that's if you're already a huge tank anyway) it's basically always beneficial to take... A 'must-have' kind of thing.

Though I'll grant, this is without considering there's a limited number of trait points you might want to spend elsewhere.
