Randomize leves

[Tigercub]

Nice idea. I say go a step further. Have the monster pool include rare NM spawns.
Leves would be a little more exciting if once in a while you got thrown a curveball with a chance of a nice reward.

For example, maybe in the levequest "Bombs Away" there could be a small chance for Bomb King to spawn, and he might drop a rare/ex HP ring. And in a necrologos leve you may never know what kind of NM might show up.
