When you trade, use mantra(R) + W to heal yourself, note that it heals you 20% of you MISSING healtg so the less hp you have the more it heals. If you dont need health you can use mantra(R) + Q to get more damage. Bind your W to enemy then use E to proc W easier and then use mantra(R) + Q for damage, poke enemy as much as possible as it reduces your cooldown on R (mantra).

Good point of this build is you insane survivability, you can push pretty deep without having to worry where the enemes are as you can easily escape from almost anyone unless its five of them there. Bad points are slow wave clear and low turret damage.

Note that this build server mainly for fun, dont use it in ranked modes, your temammates might get tilted or angry. Build is pretty tilting for enemy team tho, especially for greedy top laners.
