Ascending Meta Magic Rods

Ascending Metamagic Rods hold the essence of a metamagic feat, allowing the user to apply metamagic effects to spells (but not spell-like abilities ) as they are cast. This does not change the spell slot of the altered spell. Ascending Meta Magic Rods are use-activated (but casting spells in a threatened area still draws an attack of opportunity). A caster may only use one metamagic rod on any given spell, but it is permissible to combine a rod with metamagic feats possessed by the rod’s wielder. In this case, only the feats possessed by the wielder adjust the spell slot of the spell being cast.
Possession of a metamagic rod does not confer the associated feat on the owner, only the ability to use the given feat three times per day. A sorcerer still must take a full-round action when using a metamagic rod, just as if using a metamagic feat he possesses (except for quicken metamagic rods, which can be used as a swift action).
