Automatic Still Spell( Epic Level Handbook, p. 51)
You can cast any of your lesser spells without gestures.
You may cast all 0-, 1st-, 2nd-, and 3rd-level spells as stilled spells without using higher-level spell slots.
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 stilled with no adjustment to their spell slots. Thus, a wizard who took this feat twice could still 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).
