In a recent session I had gotten a CON buff from our Skald, and in the meantime, gone under and failed a couple of saves. It just so happened that our Skald also went under in the same fight, which "hurt" me for the 5 hit points I got from being level 5 and getting a +2 to CON. This was exactly enough "loss of hit points" to kill me, since by losing those hit points I fell down to a negative health equal to my total CON score. Is this intended? If you 've taken damage equal to (or over) what you got from the CON buff, do you lose even more current health when the buff runs out? Even to the point of death?
