Starting at 2nd level, you can infuse magic items that you wield with the power of hellfire. Whenever you use a charged magic item (such as a wand or a staff, but not scrolls and potions), you can apply one of the following metamagic effects to your next use of the item: empower, extend, maximize. These effects work just like the metamagic feats of the same name. Using hellfire infusion is a swift action. You can use this ability a number of times per day equal to your Charisma modifier (minimum one). When you infuse an item with hellfire, it glows briefly with fiery symbols that are disturbing to look upon.
