Lich's bane gives you MS, which is very good on kassadin since it can let you outrun people withough having to waste mana on riftwalk.

It increases your mana pool, that's also perfect for Kassadin who needs insane amounts of mana.

It gives MR, which makes him even more anti-mage and when combined with a Zhonya's Hourglass will give you enough resistances to avoid gettting 1-shot at higher levels. (I usually don't build anything else except a zhonia and a lich's bane in terms of resistances)

It gives your 80 AP, which is more than any other AP item excluding rabadon and zhonia (and WotA); something Kassadin tends to scale on pretty well.

It adds a 1.0 AP ratio to your burst that you can actually place: you usually riftwalk on the target, Q, E, keep autoattacking if they flee, run if they don't. You'll land 1 or 2 autoattacks anyway, so why not make the most of it and use that passive? Kass's AA animation is pretty good and you'll usually end up in melee range of opposing champs; meaning you can place that extra burst withought placing you in significant more danger than usual.
