You are the Wildest of all mages

Prerequisites: Wildmage, Infinite Power! (maybe...), Epic Wildmagic, base charisma 25+, Deed

Benefit: You now determine your caster level by rolling with a d8. In addition all abilities, that need you to roll maximum value upon determining your CL now also trigger if you roll one lower than maximum value. For example you can trigger Wildmagic if you roll a 7 or a 8 when you determine your CL.

Special: To take this feat the Wildmage has to have rolled maximum values two times in a row while determining his CL before.
