      Also currently all players on the same map are affected, for the same

  Maybe - hard to say for sure - one would think the cost should be pretty fixed 
(if the party is on mixed maps, would be sort of annoying to not have enough 
mana to cast the spell because someone popped onto the map you're on).  Perhaps 
the best thing to do is limit the number of people the spell will effect, going 
from closest to caster to farthest.

  One note - one should not user comparisions of op->map to check for same 
mapness - use 'on_same_map' - checking directly won't work correctly on tiled 
maps, which is all the outdoor maps.
