I have Resist 10 Fire.
I get hit for 13 points of fire damage, so normally, under these circumstances, I'd take 3 points of fire damage.
What if, because of another ability that triggers on becoming bloodied, I really want to take the full amount of fire damage and become bloodied?
Do I have that option? Can I voluntarily suppress the damage resistance? If I can't suppress it, can I end it in a way that lets me take that damage?
