Charisma Puncher! Need help selecting feats

[Xintas]

I am looking for a way to make a monk who punches people with his good looks and magic. By combining Ascetic Mage and Arcane Strike with Enlightened fist and Abjurant Champion on a Sorcerer/Monk build, I have a pretty good (see: fun) build that lets me do one big hit (using ACF Decisive strike).

Arcane Strike to sacrifice a spell (free)
Ascetic mage to sacrifice a spell (swift)
Fist of energy to add 1d6 damage (free)
Decisive Strike to double damage on the attack
Arcane Fist to use a touch spell (free)

Possibly:
Metamagic Specialist to cast a Quickened spell (free)

I know it is hardly optimal, but its fun and I kinda dig it. Can you think of any other way to put as much damage as possible into a single hit? I want this guy to rage out and just drop stuff. I still have feats open at 3, 12, 15, and 18

Greater mighty wallop sounds like a spell you want. It can bump your unarmed strike damage up to 8d6. Get a slam or claw attack and mighty wallop that as well, then pick up the beaststrike feat to add the two together. That will give you 16d6 base damage.

If you can work in some turning somehow, there's a divine feat to add charisma to damage.


Also, depending on what level you're building for, going with Bard/Sublime Chord instead of Sorcerer as your casting base gets you access to Snowflake Wardance (cha to hit), and Inspire Courage (which you can proceed to optimize. Dragonfire Inspiration would be fitting with this build, as it's letting you stack on yet another source of energy damage to your punches), but it would require Chaos Monk to work (dumb alignment requirements)

Battle Dancer from Dragon Magazine and the Dragon Compendium might be better than Monk for entry because of a ton of Charisma synergies and it may allow you to double stack Charisma to a number of things that are punchy.

Sorry, I should have been more clear on sources. It can only be from non-campaign specific 3.5 books with the exception of tome of battle. The classes are set at this point; I am really just looking for feats, gear, and sorcerer spells that might help.

At this point, more damage would be good, but some utility or a way to get additional spells would be just as welcome.
