Greetings! I've just recently started using the protection spell on my necro mage (no use for it playing a dexxer for all these years). I know it reduces your faster casting by some amount, but my question is how much? Does it reduce it to 0, lower it by 1 or 2 etc. Can it take you below 0? I've asked a handful of folks and have yet to get a dependable answer. Thanks!
