Sudden Metamagic - Please critique

[Angel Tarragon]

Hmm, I don't like requiring you to already have the feat. Sudden Quicken, for instance, then becomes useless for sorc's.

You are absolutely right. One of my houserules is the Quicken Spell only takes up a spell slot two levels higher the spell's base level. Then I have a rule that benefits Sorcerers; they are able to cast an amount of spells as quickened spells (without having to have the feat) per day equal to their base (before magical modification) Charisma modifier.

Of course, no form of Sudden Persistant spell will be balanced, but maybe that's a problem with the Persistant Spell feat. ^_^

Right. The Dm should feel free to allow which metamagic feats Sudden Metamagic works and doesn't work with.
