umm.. what?OP doesn't have Epic Spellcasting
From the OP:
Non-epic spells are 9th level... soo.... yeah he definitely has epic spellcasting. I'm not sure what you're reading.Wizard 20/Epic Wizard 9/Effigy Master 1 [.....] I've got 3 10th level, 2 11th and 2 12th level spells
He's right about one thing though.The summon speed is one of the best ones, period.You can also bring in some pretty scarily-powerful creatures through the Summon seed, and generally snap the game like a twig (especially if he uses DC mitigation). Summon creatures with big spellcasting (or strong anti-construct abilities) to do your dirty work for you (or just aid your DC-mitigation rituals ).
