Cern the destroyer( 800-1000 crits)

you want to poke a lot early game focus on farming and pokes over kills. Around lvl 8 you will do dmg. If you land your autos you can box and contain almost anyone. Keep everyone far away and save your dash for either confirming a kill or escaping. After you get ninja boots you will do good dmg and thats when you start boxing but its not until you get deathbringer until you are unkillable unless you are stupid and 1v3 or something. Use autumn stance for shredding the tanks and winter or summer for anyone else. Use spring or summer for minions. Make sure you have an exit plan before engaging. For the combos you have your 2 for root and auto barrage or auto and box, root and ult with winter. make sure to dash into them if you alt so you can get more hit on them. In team fights stay back and take down any tanks that attack your team. Ult the tanks when they push then go for the squishies. Late game you are unkillable if you land your autos. If you box right you can 1v5 but you have to land every auto attack. Back to early game, poke the hell out of them, you do alot with your summer stance and mace. Back when you have 1550 gold for boots then you can dominate duo lane with a good support. If your support sucks then stay back and farm more until you get enough for winged and deathbringer. If you need extra life steal build it instead of executioner. I would build Asi, it has pen which you need to shred.
