Maybe grab Greater Ruin and Hellball instead, or any other combination of epic spells, or even Epic Toughness. Things I would think of tweaking: The last two feats (Epic Mage Armor and Epic Spell Penetration) can be replaced by anything, I would say. Matures late in arcane power, and you are actually quite easily dispellable for most of your career.You would lose an epic Wizard feat (not too bad) and delay DevCrit+Autostill III by a lot. More balanced starting abilities would give the same level 40 character with a net gain of some HP and some Fortitude. Low HP, this is mainly due to my choice of getting DevCrit as soon as possible.Acceptable naked warrior attack (23/18/13/8 attack schedule at level 20, and 39/34/29/24 at level 40, can be buffed with Haste).Undispellable Wizard buffs (Flame Weapon, Keen Edge, GMW, True Strike, Bull’s Strength plus all the defensive stuff).Devastating Critical at level 24, no stellar DC but it will always threaten enemy mages.I will only comment “great minds think alike”, and bow to a probably stronger build. What’s not to love in a charging dwarven warrior with 39 BAB and 4 attacks, wielding a flaming longsword and surrounded by arcane glyphs of protections, and who is also an undispellable autostill mage? While tinkering with this, I found this build by grizzled_dwarflord which is basically the same except less greedy and with no autostill feats.

I wanted to share my first attempt at designing a spellsword which I actually believe could be decent.
