[3.5 Core] Boosting the sorcerer (PEACH)

[Alefiend]

Sounds like someone hasn't heard of The Mailman. The feat Arcane Thesis (which is incredibly broken) and the metamagic reduction class feature of the Incantatrix would allow it for something like this:

Maximize Spell becomes +1, Empower Spell becomes free, Twin Spell becomes +2 and Repeat Spell becomes +1, for a total of an 8th level spell (Orb of Force is a fourth level spell)

So, combined with the Quickened orb of force in the same round, a Sorc 6/Incantatrix 10/Full Spellcasting 4 would deal 25d6+180 force damage with no saving throw (if all four ranged touch attacks hit, and touch AC is always underpowered)

Of course, if you take a PrC, you won't get the free Quicken capstone ability.
