Transcendent Learning

Your command of magic has transcended that of ordinary mortals.

Prerequisites: Advanced Learning, any metamagic feat, able to cast 2nd-level spells from at least two spellcasting level progressions.

Benefit: Your caster level for any spellcasting class that you have levels in is equal to the sum of all your levels in all spellcasting classes you possess, if it does not already exceed this value.
