Making a "Control Blaster" in PF. Help?

[Tokuhara]

I suggest taking a look at Firefall. Like an advanced Pyrotechnics, but it deals damage and has a huge radius.

Maybe combine this with some of the other suggested metamagics? Firefall + Dazing Spell = Damage, light people on fire and daze them for 4 rounds while they burn. Sounds fun.

#1, don't forget they are also blind
and 2, let's say I lit some moron on fire, theoretically, I could loophole this spell...
