My proposed Sleep Spell, would be like this:
-There is a semi-fixed amount of time an enemy stays asleep if the spell ever succeeds
-The spells has a % chance to work. the stronger the spell the more % chance that the enemy will fall asleep
- A "100% chance to sleep" spell would only be attainable by the strongest wizards.

I'm rather perplexed about how this whole "extended" knock-out system could/would work, so sorry i don't have any half-decent ideas about how it should be implemented, I'm gonna leave that up to you guys. I just know i want to be able to go through the game as a peaceful warrior (I'll still be slaying the dragons though)
