Chilled to the Bone (45% CDR)
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is a short guide, considering I am not focused on teaching you Kassadin, but instead on sharing the knowledge of this enjoyable build. I may add more to the guide, but for now, this is all I have!
Summary of the Build
With 45% cooldown reduction, your ult will have a tiny 1.1 second cooldown! Match that with an amazing mana pool with Seraph's Embrace and Rod of Ages and fantastic mana regen from your w and Athene's, it allows you to get out of a multitude of situations and to chase targets with ease. As long as you play smart in the early game, late game will be a breeze with an unmatched output of damage.
Make sure you have a team with great initiation/frontline. Kassadin is a very squishy champion, meaning you should never be the initiator in a fight or you will face the severe consequence of death!
I hope you enjoy my 45% CDR build! I highly encourage you to give this wicked fun build a go, and I'll expect to see you on the rift, summoner!
