Hmm, I see your point, but at lower levels it can only be used against helpless prisoners so there's a limit on the number of times it can be cast besides the technical maximum of 24/day. But yes, there are situations where the spell would be very powerful indeed. The Ecomancer class feature that allows them to regain 1/3 of their maximum spellpoints after one hours rest in natural surroundings is generally more powerful, but that's part of the balance between the classes (though it is a precedence). But, heh, I gratefully accept your modification. You're a lot cooler about this than most DMs would be. Kudos.
