Infuse Sabre (Su)

Once per day at 4th level, a death slayer can infuse a wielded sawtooth sabre with positive energy as a swift action. This infusion of energy lasts for 3 rounds. When brandishing an infused sabre, a death slayer’s channeled energy damage increases by half (+50%), and undead take a –2 penalty on all saving throws against her channeled energy and against any spell she casts. At 7th level, she can infuse a sabre twice per day, and at 10th level she can do so three times a day, but she can have only one infused sabre at a time.
