Ability details
Void Stone
Kassadin takes reduced magic damage and ignores unit collision.
Passive — never cast
Null Sphere
Kassadin fires an orb of void energy at a target, dealing damage and interrupting channels. The excess energy forms around himself, granting a temporary shield that absorbs magic damage.
Cost 60/65/70/75/80 ManaCooldown 9/8.5/8/7.5/7sRange 650
Nether Blade
Passive: Kassadin's basic attacks deal bonus magic damage. Active: Kassadin's next basic attack deals significant bonus magic damage and restores Mana.
Cost 1 ManaCooldown 7sRange 1
Force Pulse
Kassadin draws energy from spells cast in his vicinity. Upon charging up, Kassadin can use Force Pulse to damage and slow enemies in a cone in front of him.
Cost 60/65/70/75/80 ManaCooldown 21/20/19/18/17sRange 400
Riftwalk
Kassadin teleports to a nearby location dealing damage to nearby enemy units. Multiple Riftwalks in a short period of time cost additional Mana but also deal additional damage.
Cost 40 ManaCooldown 5/3.5/2sRange 500

Counter plan — how to beat Kassadin
Deny the reset — it wants a kill to come back out; a warded exit removes it
Dodge the primary — its rotation is one skillshot; sidestep it and the rest is chip
Punish the cooldown — Kassadin is exposed while its rotation is down
Ward the flank — vision is what turns its best opening into a worse one
Respect the spike — Riot rates the kit 8/10, so a practised player gets more out of it than the average

Methodology
- Data window
- 512,340 games on patch 26.16, Ranked Solo/Duo, NA. Last refreshed 20 Aug 2026.
- Rank aggregation
- Emerald+ and above, pooled. Splitting further leaves samples too small to separate a real effect from noise.
- Role assignment
- A champion is filed under the lanes it actually plays, not the one class it belongs to — which is why several appear in two.
- Counters
- A matchup, not a tier gap: how this champion does into that one specifically, over that pairing’s own games.
- Minimum sample
- The confidence indicator beside every rate is driven by how much of the window this champion appears in. A low reading means read the figure loosely, not that it is wrong.
- Why a build is not a cause
- The best-scoring build is the one the best-placed players happened to take. Correlation is what a rate can show; it is not evidence that buying those items caused the wins.
- Where the numbers come from
- Names, classes, lanes, abilities, items and runes are Riot Data Dragon. Win, pick and ban rates are derived samples — Riot publishes none of them, and nothing on this page presents one as measured.
