[QUOTE="Sado, post: 2057831, member: 20589"] I don't have my books with me, but it went something like this: Every spell has a Casting Threshold-A number of points needed to complete a spell once you start casting it. You have a Spell Bonus (I think thats what it's called) similar to your Attack Bonus. To cast a spell, you roll 1D20 + your Spell Bonus. If it is higher than the Casting Threshold you have cast the spell. If your roll is lower, record what your roll was, and next round you roll again, adding your total from the first round. Do this every round until the total is higher than the Casting Threshold, at which point the spell is cast. I forget the mechanic for it, but there is a chance each round that you are casting a spell that you will muck it up and lose the spell (and take sub-dual damage IIRC). It makes for interesting play because you can never be sure exactly when a spell will go off. Should you charge the mage, hoping to get to him before he finishes casting? Should you take cover before the spell goes off? As far as I remember, you can cast any spell you know as many times as you want-no daily limits. [/QUOTE]
