Bro, you said you get nashor's tooth on kass, I stopped caring about your opinion from there.

All you had to do was make some small changes. I have to down vote you now because you insist on playing Kass like an AP caster like Annie. Q + E is not enough damage to even make you viable. I don't know if you are high ELO or not, but only using 2 spells for damage is just not viable. This is not the optimal play style for Kassadin.

I don't know against who you guys play but I'm definitely not getting in melee range with kass during fights in high elo play.

I agree with M0b1us u can't fear of death you have to think to not die not fear of it!
Lich bane getting you burst allot of it!

Btw gr8 build :D

Yes, it is risky. But you have to remember who you are. You are Kassadin. You can not fear death. You don't have enough burst with two spells alone. Riftwalk only deals damage in a very small range so you really need another source of nuking. You are not a caster like Annie, you are an anti-mage. Riftwalk in after a team fight starts, kill mage with R - hit - Q+E - hit - R to escape. Let's also not forget the utility and MR bonus. Lich bane is really a great item for Kass once you get decent AP. It basically gives you an additional single target nuke. It's like AP Sion taking lich bane, you really need it or your damage output is not nearly as strong in comparison to other mages.

AA is one good item for mana issues. However you should only get it if you have other items that give mana. Just some other means of mana would really help. Runes are good and all, but that only helps early game. Also remember that you assume you are working with a perfect team that will also always give you blue. You can't count on that always happening so you need some form of back up.

I don't get lichbane on kassadin because it's risky to get in melee range during fights, actually REALLY risky.

EDIT: And for the mana problems, you will not need more mana than you already have during your laning phase if you use the runes I have. And your jungle is supposed to give you every blue, so I don't see why I would get archangels (which is the item I think you're suggesting)

All you need is lich bane and this would be a great guide. You may want to expand the guide a bit but that can be done a little bit at a time. Also don't be afraid to include more items in your suggestions. It may be a good idea to make a chapter on just additional options that you personally find to be a strong choice. Atm, I am actually liking Nashors on Kass since it makes the most of his W, gives him 25% CDR, AP and a little mana regen. Other than BV, you don't have much mana or regen so that may be a problem.

Make some updates then I will vote.

Works like a charm everyone should use it :)

This is very similar to the build I use. I have had great work with it.

Great all around guide, ganking tips were especially helpful. thanks alot
