Chose the lowest life use <<Deceive>> you will get a crit close to 200 (tips TRY to Deceive from behind so you will get 20% higher crit) << Exhaust >> and then
<< Ignite >> Hit him with melle attacks and you got FIRST BLOOD!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Start with Dorans its the best choise for First Blood Life + dmg then make Berserker's Greaves When you gona Start hiting someone you gona run fast and attack fast so the Slow from your Two Shiv Poison wont let them escape from death. After this make a zeal for movement so you gona run a bit faster than the other's much beters chances to get kill when they running. Get a Pickaxe so you gona boost your crit with Deceive and your AD and then make Shen for beter burst dmg and more mana for more hunting time!!Then try to Complete Infinity's so your gona get HIGH Crits after this increase your endurance with a Vampiric Scepter and END Trinity Force for HIGH burst dmg on opening a fight. If you see your openents can reduce your life very fast make an Warmog's Armor, But if you got no problem with diyng from an oppenent you can continue your build with The Bloodthirster and After Madred's Bloodrazor( An item what you need only if the oppenents got Champions with high lifes like Volibear or Vladimir )
