Description: You can cast any of your lesser spells with a moment's thought.

Prerequisites: Epic Level, Quicken Spell, Spellcraft (30 ranks), Ability to cast 9th-level arcane or divine spells

You may cast all 0-, 1st-, 2nd-, and 3rd-level spells as quickened spells without using higher-level spell slots. The normal limit to the number of quickened spells you may cast per round applies. Spells with a casting time of more than 1 full round can't be quickened.

Special

You can gain this feat multiple times. Each time you take the feat, the spells of your next three lowest spell levels can now be quickened with no adjustment to their spell slots. Thus, a wizard who took this feat twice could quicken his 0- through 6th-level spells with no adjustment to their spell slots. This feat doesn't increase the casting time for those spells that normally become full-round actions when cast in metamagic form (including bard spells, sorcerer spells, and spontaneously cast spells, such as a good cleric's cure spells).
