Call ur mias

U should have finish ghost blade by now at lev 9
Get blood sword for dmg
Continue push lane to kill turrets
Be aware of the map
Make sure u don't get gank by champions u can't fight even tho u can take them
Help teammates
Buy some wards to ward baron and dragon
Just don't die and farm

U should have phantom dancer now
U do crazy dmg and break turret fast
Get baron and end the game
Mostly game ends when I'm building blood thirster

To charge passive faster and do more dmg when my skills r on cool down

I find that my dmg suks if I go tanky pantheon and pantheon is suppose to do dmg not tank

Armor pen is for more dmg
Armor to get better early game and be harder to die
Magic resist to counter mages
More armor pen just because u kill carrys easier

I go 21/0/9 because I want to do a lot of dmg so I get points on offense
The utility is just for the mana regen so I last longer in lane

Berserker boots cuz i need atk speed. I get ghost blade first cuz of the ghost ability and atk speed with armor pen. Also some dmg. Blood thirster because ad need dmg and some life steal to stay in lane. Phantom dancer because I move faster, atk faster and cric chance.
Infinity edge cuz of passive and ad. Also adds cric chance. Last whisper cuz of tanky late game ppl. Guardian angel just incase I die. Also makes it harder to take me down.

Just tell me what u think I can do to improve this build and Ty for looking at this build.
Also my LoL name in the game is Imnoobxd4. Add me if u want to.
