Abilities and Skill Sequence
His Q is his main source of damage so max it first. Use it to poke champs and deal massive damage in the later game. Since you can pick up the axes and reduce the cooldown by 4.5 seconds this is a great tool for damage and chase, and I guarantee you can chase almost any champ down you want. You can chain his Q's by hitting and picking up the axe chasing, then hitting and chasing again, etc.
I really like his W in this build because of the AMAZING lifesteal he can get, so I typically start maxing his W at around level 12.
E is usually second ability to max, but around the end of your leveling I tend to balance the W and E progression due to his W's attack speed and lifesteal.
The lifesteal from your items in combination with vampirism and runic armor PLUS your W will make you un-1v1able. His W also increases lifesteal the lower you are, so you can even 1v1 people when you are 1/4 hp unless they are very high burst, or if they have a lot of kite.
