Hello people of mobafire. Kassadin with this build can be played like he was played season 10. Farm up maybe go slightly behind in lane and be able to 1v9 with good sidelaning. This build has a good balence of tanky burst and dps with lots of movement so the downside is lack of resistances like armor and MR. But we have conditioning for that to make sure we are not fully dying to lethality and MPEN. Your gonna be about as tanky as a bruiser and do the damage and have mobility like an assassin. So just play for lvl 16 and remember you spike hardest at cosmic drive statisticly with a 79% winrate last item.

You need to maintain good farm (atleast 8 Cs a min) while pushing and doing useful things. If you do nothing like just farm but cant pressure turrets then your team may get **** on too hard because you are worth nothing for too long. The way you can avoid becoming dead weight is spliting turrets and grabbing picks when moving lanes or just farming enemy JG. If you can maintain this farm and get items and levels before your enemy you will be worth a lot later. Just pray in the church of kassadin and you will be given god mod menu lvl 16.

Ok so now your lvl 16 and have lich bane (ATLEAST) and are 2 lvls up on enemy team from the amazing farming. You are now capable of 1v5ing if they situation is right. All you need to penta is 5 seperate 1v1's. If you can manage such a thing it is very likely you will just penta. Because no one and I mean no one can solo fight you unless they stack mr and have been fed entire game. If you went even in lane and can make it to late game then you will win 80% of games past 30 minutes. The best way to play the teamfights are to wait for cc spells to go out or atleast most of them to go out. Then just go on easiest to pop dmg dealer then just keep going on everyone else while healing and having ur R every .89 of a second until enemy team becomes depressed IRL from your kassadin gameplay.

I hope this guide has and will help you and please try out this build and runes set you will not regret it. Again best way to play this build is scared early but then jesus irl late game because of god hacking into game at lvl 16 and providing his help.
