Anyway, back to the MT:I think PsiSeveredHead is on to something. The MT just doesn't work very well past 10th level. On the one hand, the MT is too good at full caster progression; a Clr3/Wiz3/MT 10/Acm4/MT 10, for instance, tails a Wiz30 only in terms of spell penetration, and could easily take three spell power high arcana to match that. On the other hand, epic feats confer a degree of power and specialization that is hard for even the most diverse character to match; a Wiz10/Lor20, for instance, would have a pretty big advantage over an MT even if the MT got full double spellcasting progression, as long as the MT had fewer epic feats, because the MT wouldn't be able to pull the Auto Quicken/Multispell nastiness as quickly, would have fewer truly high-level (Imp Spell Capacity) slots, and thus less raw power. So it's a hard call. IMHO, the MT should just cap at 10th level and leave the PC with the option of taking dedicated arcane or divine spellcasting PrCs.
