Huh. Limit Break anyone? Works best with a kalashtar.
What about this?
Kalashtar ardent 1/warblade 13/abjurant champion 5/warblade +1
Feats: Quicken power
Manifest
quickened fission, then both you and your duplicate initiate
time stands still on the same target. If you want to be crazy, do this in gestalt with arcane duelist and eternal blade on the other side. A shame you can't Twin
fission, because if you could combine that with a theoretical
swift fission power...
EDIT: Dominant Ideal = reduce cost of metapsionics by 2 and you don't need to expend focus. So once or twice per day your fighter can use Maximised Empowered
tornado blast.
