Build, runes, synergies, counters, lore. Kassadin is a high-mobility mage assassin in League of Legends known for his ability to traverse the battlefield and burst down enemy champions with his powerful magic.

General Description

Kassadin is an anti-mage champion who excels at taking down magic-based opponents. His passive ability, Void Stone, grants him magic damage reduction, allowing him to withstand the assaults of enemy spellcasters. Kassadin’s ultimate, Riftwalk, grants him unparalleled mobility, enabling him to quickly engage or disengage from fights. With his potent burst damage and mobility, Kassadin is a formidable threat in the mid-lane.

Kassadin Build

Kassadin typically builds items that enhance his ability power, mana sustain, and cooldown reduction. Items like Rod of Ages and Seraph’s Embrace are core to his build, providing him with increased mana, survivability, and scaling damage. Kassadin can also consider items like Lich Bane or Zhonya’s Hourglass for additional burst or defensive options.

Kassadin Runes

In the rune tree, Kassadin often runs Electrocute as his keystone, which amplifies his burst damage potential. He can also choose Fleet Footwork for increased sustain or Phase Rush for additional mobility. In the secondary tree, Domination with Cheap Shot and Ravenous Hunter can provide additional damage and sustain.

Kassadin Synergies

Kassadin synergizes well with champions who can provide crowd control or set up opportunities for him to engage, such as Sejuani or Lulu. He also pairs well with champions who can protect him and provide utility, like Janna or Thresh. Kassadin’s mobility allows him to quickly follow up on teammates’ initiations and deal massive damage to priority targets.


Kassadin can struggle against champions who can out-range him or burst him down before he can unleash his damage. Long-range mages like Xerath or Vel’Koz, with their poke and crowd control, can pose a significant threat to Kassadin. Additionally, champions with high burst damage and mobility, such as Zed or LeBlanc, can make it challenging for Kassadin to survive in team fights and find opportunities to engage.


Kassadin is a void-touched mage from the city of Shurima, who had his life forever changed when he encountered the destructive power of the Void. Seeking revenge and redemption, Kassadin underwent dark transformations, sacrificing parts of his humanity to gain powerful void magic. He now wanders the world, hunting down Voidborn creatures and those who would unleash the darkness.
