Rod of Power Source

This heavy, softly humming rod grants the wielder a +4 bonus to Conjuration school spells' DC and the ability to make up to five spells they cast per day empowered, as though using the Empower Spell feat. Regular rods can be used with spells of 6th level or lower. Empower Spell: All variable, numeric effects of an empowered spell are increased by half including bonuses to those rolls. Saving throws and opposed rolls are not affected, nor are spells without random variables.
