Prerequisite: Magus 6

Benefit: An magus can transform her weapon into a glittering weapon of pure energy by channeling her spell slots directly into it. The magus can expend a single spell slot to increase her weapon’s enhancement bonus on attacks and damage by an amount equal to half the slot’s level. This bonus can improve the weapon’s enhancement bonus on attack rolls and damage rolls, or it can be spent on weapon special abilities that are expressed as an enhancement bonus. This bonus lasts for 1 minute per magus class level, and the magus can use only one spell slot in this manner at a time. If a magus activates this ability while a previous use of it is still in effect, the new bonus replaces the old one—it does not stack.
