Improved Metamagic

(Epic Level Handbook, page 59, DnD 3.0)

[Epic]

You can cast spells using metamagic feats more easily than normal.

Prerequisite

Four metamagic feats, Spellcraft 30 tanks

Benefit

The spell slot modifier of all your metamagic feats is reduced by one level, to a minimum of +1. For instance, you could cast a quickened spell as a spell of three levels higher rather than four levels higher. This feat has no effect on metamagic feats whose spell slot modifier is +1 or less.

Special

You can gain this feat multiple times. The effects stack, though you can't reduce any metamagic feat's spell slot modifier to less than +1.
