Tiali said:OOC: Same rolls for everyone where it applies. If your hurt add 7 hp, if your poisoned remove 2 of the poison damage. (He is currently using the spells status and detect poison, so if your not hurt or poisoned, he doesn't use said spells.)
Well, if you got poisoned multiple times (by multiple stings or whatever), you could accumulate enough Con damage that the 2 points of healing wouldn't remove it all.....
But HP lost from Con reduction is automatically regained when the Con score is healed sufficiently. The HP loss isn't damage, just a side-effect of having your Constitution modifier reduced.
