How to play Kassadin in ARAM Mayhem

Kassadin is a strong pick in ARAM Mayhem on patch 26.21: tier A, #38 of 173 champions, with a 51.6% win rate over 825,295 games. Riot rates it 8/10 for difficulty, so give it a few games before you judge it.

86% of Kassadin's damage to champions is magic, so enemy magic resist is what slows it down. It brings almost no crowd control, so it relies on teammates to set up kills.

The AP build, ability power items, is both the most played and the top-ranked path: Rod of Ages, Manamune and Archangel's Staff, with a 52.8% win rate over 639,393 games. On this build 66% of players skip boots and spend the slot on another item.

The cards that do best on Kassadin are Blue Barrier, Mind to Matter and Final Form. Cards built around ability haste fill most of the top of its list, followed by ability power. Skip Pursuit of Haste and Steel Your Heart when you can: they do worst on Kassadin. A pair to look for: Infinite Recursion with Blue Barrier.

Take Flash and Clarity (1% of players); Mark is the common alternative. Max E (Force Pulse) first, then Q, then W.
