After researching some build strategies, I saw some offhand comments about builds that can hit for obscene amounts of damage, and I made it a personal quest of mine to determine which build can hit for the most damage (in a single hit).
Neverwinter Nights being a game which you can modify in almost any way, an inquiry like this requires some parameters: Plain 1.69, with HotU, but no Hakpaks, Level 40 PC, with a +5 weapon, with full +12 bonuses to every Ability, against an enemy with no particular Damage Vulnerability, with buffs only from the PC’s spells and special abilities (i.e. not from potions or NPCs).
Since this is a forum topic, there may not be a single right answer because you may want to challenge some of my restrictions, and that is all right here. I asked this question over on Stack Exchange, but they didn’t seem to like it much.
