A spell that has me somewhat confused

[playingtokrush]

fair enough if not facing casters then you can have the benefits of the heals

Well, this is exactly the situation in which you'd use Amplify Magic.

I asked a high level mage about this , he said it knocks off some spell damage , then he ran off , so not much of an explanation . So does it indeed work like Dampen magic ? if so why have dampen magic at all ?is it just worded wrong ? or is it not party member at all but cast it on a mob to make them take more damage . clarification on this would be nice , cheers .

The mage is full of crap. It's just the opposite of Dampen Magic, but still only works on party members: increased damage from spells and increased heals.
