Alright. This build consists of a Tank with average damage that can be really helpful when it comes to pushing enemies at high and low level.

First 3 levels you want to go with a ranged and spam Fire Stomp whenever you have it. Stick with killing mobs, but if you feel greedy, a easy way to kill is to either, charge them against your towers and stuning around them or push'em towards your friendly assassin.

By the time you get Lightning breath you can start tanking camps with ease.
Don't be worried about wasting this skill on just one target.

But when you get Siphon The dead, the real fun starts.
Focus mainly on pushing towers and always go for the health regen mobs.
By this time, towers wont do much.

Get your team to help you with some camps and push foward without a worry.

Have fun and I hope this works as well for you as it works for me.
