TheSquid
After tinkering and playtesting, I can share an updated version.
As a level 40 character, the build lost: 1 AB, 40 HP, 1 Concentration, 1 Spellcraft, 13 Search.
It gained: Blind Fight, 16 Discipline, 22 Spot. If True Seeing is not nerfed where you play, maybe Spot is not needed: in this case, swap the last CoT and Fighter levels and put those points elsewhere. Chosen weapon is now Scimitar for the better crit range (12-20 with Keen Edge).
Leveling up, all the pre-epic Wizard levels are now gotten as early as possible. EWS is delayed to level 40 as you don’t really rely on that, and EMA is moved to level 36. You have -1 to all saves and -5 Spot in levels 24–39 compared to the previous version, and -10 Discipline in levels 34–38.
