Any mage who wants to be good must start as a glacier/fire because you can use the glacier to slow down the enemy and then use fire to inflict a lot of damage. I am a lvl 42 mage and i can kill DTS, hell hound, and ash bymyslef without too much problem. DTS gave me 18K of xp when i first killed it with premium at lvl 39. Also when a mage reaches lvl 45 completely stop killing whatever you were killing and go fight harpys. Harpies are birds that only mages should be allowed to kill like i never see a warrior there its usually like 4-6 mages a preist and one rouge. the mages just use the rouge for swift and wolf and the preist for the heal and the buff.

a mage will start quickly gaining lvl after 45 like this
