I dont know if its released or its old. If it is im sorry for that.
Well for that you need one priest on full discipline ( must have Improved divine spirit ) and one mage for example. Improved divine spirit gives 10% spell dmg + some spirit. When priest buffs mage, priest must logout. Till hes logout mage must remove the buff and these 10% spell dmg are stacking. Priest login, buff mage again and logout, You can do this all day and if you use talent stacker to put 20 points at Ice Shard you will make craazy crits with frostbolt. I made my mage with 1 000 000 critical frostbolt :)
