Select your target, use Lightning Bolt 30 yards away from him. Then the target will run towards you, use Fire shock when he is 20 yards away then carry on with Lava burst. When you using Fire shock, he should have got a debuff on, if not resisted, will make your Lava Burst become instant spell. When at melee range, use the following spells, Sormstrike, Lava Lash and Earth Shock. They all have CD, so use any of them when it's ready. Because we clicked Maelstorm Weapon on talent tree, you should now have a Maelstrom Weapon buff stack. With the stack of 5 times, Lightning Bolt will become instant spell. Use it when it's ready. Maelstorm Weapon can be benefit by weapon speed, at mean time, can be triggered by Stormstrike and Lava Lash. With the effects of Winfdfury Totem and Flurry, the debuff can be easily stacked 5 times to trigger the instant Lightning Bolt. Repeat with above spells, you should kill the target very soon.
