Greatings summoners and welcome to my guide to Kassadin! I present myself: i am Dandere90, season 6 gold 5 Kassadin main and the third one in entire world for mastery points. In this guide i will show you my personal playstyles to this incredible champs that, even the nerfs, is still very strong and in the current meta performs very well both in midlane (expecially here) and also in toplane (if you want you can also try him in the jungle, but don't do it in ranked games :D).

The runes for Kassadin are fairly tipical for ap mids: standard flat ap quintessences and magic penetration marks. The two other type of runes change in base of the matchup: flat armor seals against ad mids (Talon, Yasuo, Zed) and scaling health against ap mids (you can also swap scaling ones with flat ones in case of an early aggressive lane bully as Leblanc); scaling/ flat ap glyphs or scaling/flat Cdr ones if you are against an early low threat opponent (Katarina, Veigar) or mr scaling/flat against dangerous early mages (Lux, Syndra).

The masteries for Kassadin are flexible enough in base of the difficulty of the matchup. For easy ones i recommend 12/18/0 focusing on Ferocity and Cunning trees: for the first one we rely on Feast to sustain in the early game, Natural Talent for the scaling ap (that synergize well with our scaling runes) and Bounty Hunter to let us feed and then do more damage; for the Cunning one we take Wandered for a better roaming, Secret Stash for the sustain, Merciless for the execution damage, Dangerous Game to survive to close fights, Intelligence to put our ultimate on 1.1 cd with 45% cdr and Thunderlord's Decree to increase our burst.
