Rods are scepter-like devices that have unique magical powers and usually do not have charges. Anyone can use a rod.
Physical Description: Rods weigh approximately 5 pounds. They range from 2 feet to 3 feet long and are usually made of iron or some other metal. (Many, as noted in their descriptions, can function as light maces or clubs because of their hardy construction.) These sturdy items have AC 9, 10 hit points, hardness 10, and a break DC of 27.
Activation: Details relating to rod use vary from item to item. Unless noted otherwise, you must be holding a rod to use its abilities . See the individual descriptions for specifics.
Special Qualities: Roll d% and consult Table: Special Qualities below.
1 Intelligent items have extra abilities and sometimes extraordinary powers and special purposes (see Intelligent Items). Rods with charges can never be intelligent.
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. All the rods described here 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 a specified number of 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).
Lesser and Greater Metamagic rods: Normal metamagic rods can be used with spells of 6th level or lower. Lesser rods can be used with spells of 3rd level or lower, while greater rods can be used with spells of 9th level or lower.
