Hmm.  Looking over the Artificer class's class features, I think I should actually have 9 more HP than I'm listed as having.  Kairon's got the Arcane Rejuvenation class feature, which gives out half his level plus his Intelligence modifier in temporary HP to any ally who uses a magic item's daily power.<br/><br/>I used the daily power of the Casque of Tactics to switch my initiative roll with Roland's, so I should have gotten 9 temporary HP then which would have been taken off when all those Dryads took a chunk out of my HP on the first turn.  Which, combined with the Curative Admixture he just tossed to me, would mean I'm now back up to full...
