Amastan Adder's Stasis:

If successful, the caster can place a character under Stasis. A character in Stasis cannot be harmed, does not age, and cannot be played. When the spell ends, they are returned to their exact condition at the time the spell was cast. If the target is unwilling, increase the cost by 2, and a contested magic check is made. The spell ends of the target is affected in any way by an outside influence. If this is cast during a war, or in a duel, increase the complexity and cost by two. Upkeeping a character in Stasis over an Era transition consumes all character magic of the character upkeeping the spell, and requires a DC 20 Magic check. Alternatively, this may be used to grant moderately increased chances of success when attempting to preserve something.
