Stacking Metamagic Rods and Feats

[Krith]

Can you stack a spell with a both a metamagic feat and a metamagic rod of the same type? Ie, can I cast a fireball using both a piercing spell metamagic feat and a piercing metamagic rod at the same time, for an effective lowering of Spell Resistance of 10?

[Zhayne]

No. The same metamagic feat cannot be applied to the same spell more than once.
