-Slow death now does damage in off-combat again.
-Slow death's spcost increases the more active ones you cast.
-Slow death drains sp from you if you are not in combat and have active ones
on monster(s).
-Slow death works like before if the monster is too powerful for you.
-Sense weakness spell can tell you if the monster is too powerful.

Thank Juggelo,Durand and Zin to make this possible, send bugs to me if any.
