Hmmm, then idk how much I can help. There are Dps Mage spells in game but most of them are really late into the game unless you want to Save Edit yourself abilities like Holy Shock. In this game it's almost always better to kill your enemies before they can act.
Still here's a build:
Play Warrior.
Max Strength, Toughness, Willpower. Drink Agility Juice. Use whatever one handed weapon you prefer tbh. A shield and heavy armor.
Get Flamebrand and Song of Storms, Warcry and Thunderstrike. When Level 4 change Warcry for Vanguard and Thunderstrike for Dastardly Trick. When Level 6 change Dastardly Trick for Deadly Shadow. When you get to Khor'minos buy Powerwave Tome and Flametongue Blade. Change your build to: Charge Weapon, Powerwave, Vanguard, Deadly Shadow for a Dps build.
You can also instead choose to buy a Tome of Thunderbrand (upgraded Flamebrand) with a build of: Thunderbrand, Primal Scar, Celestial Smite and Bull Rush. This build is more Bursty compared to the other one.
