The q nerf sucks a little but since you max q first most of the time, it just means that you have to be a little more careful on how you use your q for trades early game, I don't believe it will have an impact beyond level 6. As for the w since we build so much Mana anyway from at archangels plus sheen and roa, 2% won't change a lot. I really don't understand why they want to nerf kassadin, he is very balanced it seems out of nowhere for me. Oh well. Thanks for the comment.

I build deathcap before lich bane cause deathcap is a huge power spike for kassadin and the kassadin build that I play is pretty expensive so it rarely gets to the point where I have full build. Deathcap's damage boost is very helpful for oneshoting adcs and mid laners, also I have sheen for the proke after each spell for some more damage. I know sheen doesn't do as much damage as lich bane but it does pretty good damage and you rarely dont kill someone with a full combo when you have build deathcap. Thanks for the comment.

I am glad you found my guide helpful. Thanks for your comment.

I wrote my opinion about electrocute in a comment below so I won't repeat it. This guide is just my personal opinion after all, you are free to do whatever you think is best for you. Thanks for the comment.

Kassadin is meant to be played on mid. I know it can be hard but that's where he is at his best. You can play kassadin top but he was not meant to be played there and for a good reason. You can't roam from top to help bottom so you are relying on your team to do good without you and playing an assassin top means that your team wont have a tank to engage. You can play a tanky kassadin build but it's not the same as playing a tank. If you play some more games and get used to the match ups it's not that bad on mid. Thanks for the comment.

I tried many runes on Kassadin. I tried electrocute, dark harvest, unsealed spellbook, aery but of all the runes I have tried I never found a better choice than arcane comet. It gives you very good poke in lane and you can use it very often thanks to the 20% cdr you get because your q is single target spell, so you get free poke in lane. Also choosing sorcery as main tree you get the manaflow band that help you sustain your mana and gives you more damage through your ult. If I picked sorcery as second I wouldnt pick manaflow band because transchedence and gathering storm are more useful. The precision tree isn't very useful for me. It is nowhere near as useful as sorcery and domination trees. I know fleet footwork gives you sustain but for me if you are good with kassadin you can survive lane without it. If you see my profile here, you will see that I have 0.53 deaths at 10 minutes with my build, also if you see Ranked Chapter in my guide I have 61% win rate with my build and I climbed to platinum with Kassadin so it works. I rarely die before 10 minutes with kassadin meaning that fleet footwork is useless for me since the reason most people take it is to survive early game. I know that my guide drops in rating just because I dont have fleet footwork in my runes but I am not going to put something in my guide that I dont believe is good just to get better rating. So to sum it up I choose arcane comet because it helps me poke the enemy in lane and get some kills early in game. Electrocute isnt as good in lane because you rarely get the chance to use 3 spells before lvl 6 and because of that you basically get harashed for free. Thanks for your comment.

For 2 reasons. First the 10% cdr is scaling so it isn't 10% from the start of the game. Waiting till lvl 18 for my cdr to scale isn't worth for me. The second reason is that kassadin is already weak early game and not taking that extra 9 AP will make him even weaker. Thanks for your comment.

Yeah I always buy tear first but I can understand what you are saying. I thought lately about it and I am thinking of completing rod of ages before buying tear but I haven't tried it in any games because I try to learn some new champs right now. So to sum it up I think you can build rod of ages before tear if you want to. Thanks for your comment.

Thanks man.

Thanks for your nice words, it means a lot. I hope my guide helped you to win more games.

Thanks for your comment man. I am happy you found this guide helpful.
