Class and Level Geekery XVI - These Characters May Now Drive the Plot

[Quartz]

What if Xykon has the arcane preparation feat, and that's how he uses metamagic'd spells without spending a full round casting them?

That would mean he needs 12th level spells slots. Which would mean that Xykon was 26th level minimum as four Epic feats would be required - Epic Spellcasting and 3x Improved Spell Capacity. Xykon gain Epic feats at levels 21, 23, 24 and 26.
