max flame, fire knowledge, purgatory fire, magma blade, and electrostatic charge. level up lightning a little, maybe half of your level, or max it if you have the talent points. on your druid side max recover so you can heal yourself.
when fighting use flame, lightning, flame, flame. any non-elite should be dead after that. if youre strong enough and just doing quests gather alot up and use shield (electrostatic charge) and purge. when you get higher and get magma blade (elite skill), use flame, lightning, flame, magma blade, flame.
for gear, just get lots of intelligence and enough stamina to get your life up. wisdom isnt too important, but you can have a little bit so you dont have to guzzle mana pots as much.
