if you want to really break a campaign wide open with MOTUH (and probably make the DM throw a building at you) - get TK with wizard levels, and take sorcerer on the other side - Get TK as a spell in the spellbook at level 9 and as a known spell at level 10. along the way get arcane thesis (TK) at level 9, chain spell, practical metamagic (chain spell), and either easy metamagic (if allowed) or metamagic school focus - which allows you to cast chained TK as a 5th level spell.
your first MOTH level is level 10 (instead of wizard) - end result - at level 10 - you can violent thrust (barring items or other CL boosters) 13 300 LB objects for 12d6 each (so - 156d6), level 11 is more or less the same but you can also wield weapons but at level 12 you can wield 15 weapons at the same time and make a full attack with each of them (60 attacks per round).
combine with chained reached shrink item (through a rod?) on a lot of collosal weapons for extra cheese.
