Demonologists are masters of fire and fire based spells. They have some spells that are based on other elements, but most of the primary spells are fire based. They have extremely good DPS, both AOE and single target damage. As well as good DPS, Demo’s have pets that aid them in battle. These pets have some very beneficial buffs and heals. The only downside to the Demo is that they can’t take much damage. so you will most likely die a good couple of times in PvP and PvE before your really know how to handle and play the Demo.
