Surge Ritual Casting
When casting a Ritual, a PC has the option of eschewing any gold piece component cost in exchange for losing a healing surge. Any other component costs or focuses are still required.
A PC can use Surge Ritual Casting a number of times per day equal to their level.
Exception: As a general rule, Rituals with a Duration of “Permanent” are not eligible for Surge Ritual Casting. For example, you must pay the gold piece cost for the Enchant Magic Item, Undead Servitor, and Lich Transformation rituals. Shucks.
