You allways want to have ignite to fullfill your combo.

Start out with boots and three healt potions then just follow the item build that I have done. This build works everytime exept it the team does not have any AP champ. Then you can change your MoM to a more defense item like a warmogs or to an more aggresive item like Bloodthirster.

When laning try to use ur Q before using your E, this will make ur E hit more becouse your Q withdraws armor for ur apponent, and then go for some auto attacks. When trying to kill your lane partner use this skill combo, E-Q-R-IGNITE, when your ULT runs out use your E and Q again if u did not mannage to kill him with your IGNITE.

In teamfights just go in to them all using E on someone and then ulting them all knocking all up in the air. After u done that go for the AD carry. He will be a easy target for you and he will not be able to escape becouse of your Frozen Malet.

PROS
Great AoE in teamfights
Has a gapclose ability
Tanky and has alot of dmg
Very fun champ to play
Can do really crazy jukes with his W.

CONS
Not so good in teamfights without ultimate
Using ult can make you die fast if not used correctly
