Favored by ritual casters accustomed to long battles and constant warfare, Simbul's Conversion allows an individual to convert powerful spells into healing reserves. The Simbul taught this ritual to many of her apprentices, and it has since become widely employed as an emergency resource. After performing this ritual, you sacrifice any number of unused daily arcane powers and regain an equal number of healing surges. You cannot exceed your normal maximum number of healing surges per day.
