Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is Leblanc build. Leblanc is one of the best nukers ingame and i tried to enhance that by giving her 75 MagPen, basically dealing true damage to all non tanks, but then no one wants to target the tanks, do they?
Magpen reds and quints, so it'll be like they have 10 magic resist at lvl 1
mana regen/5 per lvl seals, just so we can stay in lane without using all our mana
ap/lvl glyphs, for that extra little bit.
I start with dorans ring, it gives 15 ap, 4 mp/5 and 100 hp. You can start with mekis pendantif you wanna get tear of the goddess faster, but i like dorans.
then you get boots, so you can catch the enemy, and get some moar kills.
