So I'm sittin here drinking beer and thinking about what I wanna do for a new build and it hits me, max HP. Something that can give me the most possible sustainable HP in the game as a foundation to hang some sort of DPS on. 20 Dwarf Barbarian? Maybe something like a WarPriest/Frenzied Berserker? I will TR a multi-life toon who has PL Fighter, Rogue, Sorc, and Wiz and a +5 Tome on all stats into the build that has the most theoretical HP and try to play through, hopefully getting another life out of the way.
As a diversion while I mull out some insanity myself, enjoy the Lowest Possible Hit Points in D&D 3.5 for a laugh.
