Sleep spellJolts seems a bit brutal (like Confusion, Sleep and Calm)
I'd like to extend on that. We houseruled Sleep to be not entirely effective when target is already aware of danger (target would get a huge bonus (like +50) on their RR). We like the spell as a strategy
before a combat occurs, e.g. taking out a guard before he knows there's danger, but not as a mid-combat solution, like a guard approaching, weapon drawn, ready to fight. It just feels to easy.
A one-shot mage with only that spell and sufficient ranks is a defensive hero!
As possible solutions, I propose (a) the term "unsuspecting target", which makes the spell a strategic one, requiring stealth (and a muttered spell, thus -20, making it a little harder) or (b) modification of the required RR or (c) the rule that loud noises (i.e. combat sounds) count as "somebody tries to awaken him", so lets the target repeat the RR.
Same applies to Calm.
You shouldn't be able to Calm (or Sleep) someone already poised for battle.
I have fewer doubts concerning Jolts and Confusion.
