I have a question regarding instant death type spells (quicksand, death wish, asphyxiation, etc). Does the spell points (or level) really matter? I know I tried quicksand on level 1 a bunch (which requires I think 12 or so SP) and it worked (killed a few rats).Does it work any better choosing higher levels? I know attempting a spell at a level that is yellow or orange will help train your skills faster, but does a higher level make these type of spells more effective?
