Not Updated For Current Season
Ok, first of all i would like to apologize for some poor english u might see in this guide.
ok let start.
Leblanc is an awesome one on one dps caster who exells in hit and run kills ( thats basicly what i thinks of her )
for the build now .
Ignite - well obviously great spell for finishing low hp enemies early game ( early game will determines how u would play later on this sentence is valid for like 90% of the game i personally played in) so its a cruitial spell
Ghost - well beside her ability DISTORTION leblanc has no escape mechanisms and distortion is on high CD so i got ghost
RUNES - well the rune build is pretty much standart besice the cd runes, dont know why but they works perfectly for me u might wanna chnage them for whatever works for you
MASTERIES - standart 9/0/21
Now for the game itself.
Early mid - you might wanna use you sigil of silence to harras ur opponent alil bit since its on low cd and consume small amount of mana you should be fine with mana aspect as soon as u reach lvl 4 u can actually kill ur opponent using sigil or silence followed with distortion and ethernal chains (withj ignite if needed) should do the trick and finish off ur enemy... you can repeat that several things most of my games i reach like 3 killsbefore i hit lvl 10 so just alil bit of practice and you will nail it.
early dual lane - well as leblanc u r not much of a pusher early game so what i do is basicly playing passive avoiding death or major injury but the time i hit lvl 6-7 i can start use sigil of silence and mimic combo to harras and nuke suiqshys in ur lane onceu get ur 1st kill u can wether stay in your lane or start help ganking in other lanes (leblanc is reallyu mobile champion especially when using distortion to jump across walls.
mid mid game - well in this time your team should be spreadin across the map gankin and pushing towers ur job is really moving around and hunt down any squishys u can find by the time you hit lvl 11 and ur teammates are about lvl 8-10 you should push towers and start some teamfights
dual lane mid game - well pretty much the same as said above
late game - wellafter u got ur zhonya ring you pretty much can solo any of ur enemies (unless they are all tanks) just move around the map hunt down enemies and save up gold for missing items if you and your team did good the whole game without feeding to much the enemy team u should finish and iwn this game before everybody hit lvl 18
Now for an extra part of the guide
in the build the core items are
-Rod of ages
-sorc shoes (obviously)
-Archangel staff ( for massive AP boost)
-zhonya ring ( for even larger AP boost and survivability)
-mejais soulstealer (you can stack up some AP .. ONLY IF YOU DO EXTREMLY WELL EARLY GAME, this item worked for me once so far)
-2nd archangel staff ( this last arch staff rlly boost your AP i usually do tend to get it late game).
to summerize it - this build works for me best i rarly fail and usully finish a game wether won or lost with a score of above 15 kills and less then 10 deaths following with some couple assists
so if you got any comments replys suggestions im open for criticizm have fun :).
