Not Updated For Current Season
This build requires that u know how to play kassadin, cuz if u cant own everybody this aint the build for u.
A crazy chaser
Does crazy damage
Able to get out of the worst situations
Weak early game
A spell that have to be charge up,
can run out of mana in early and start mid game
both my sommoner spells is for start game, in mid nobody can kill u then u first ding to lvl 6, but i'll agree that in late game its almost useless
Teleport is also great if u mid lane cuz of the big advantage of recall and buy items with out loosing any xp.
Cleanse can help u in some really bad siturations
Flash u may use flash for the extra tele but if u first have 20 stacks then ur tele is onlt 2,x seconds cooldown
Kassadin owns in 2 persons lanes but he also does a great job in mid lane.
In up- or downlane you will be best of playing together with a ranger or a surpoter, just keep harasing them to you get ur ulti then make a 3 spell combo: R E Q and they should die easy just keep repeating that.
In mid lane you will get some touble vs a ranger but try to haras as much as possiple with ur "Null Sphere", then u get into lvl 6 try to trick ur opponent with faking a recall and then tele over and get a kill, or simple just start hasrrasing with ur ulti and other spells, u may also try to trick him with ur heal.
