You can channel positive energy to increase the power of cure wounds spells cast near you.
Prerequisite: Ability to turn undead.
Benefit: You can spend a turn attempt as standard action to place an aura of positive energy upon each creature within a 60-ft. burst. Any cure spell cast on one of these creatures before the end of your next turn is automatically maximized, with no adjustment to the spell’s level or casting time.
