Kassadin vs Tristana Counter Pick

Draw a Bead quietly rewrites the range gap: Tristana’s attack range grows with every level from a 550 baseline, while Kassadin stays at 150 all game. Combined with Rocket Jump as an escape and Buster Shot as a knockback, she owns both the distance and the exit. Across 372 games on patch 16.13.1 Kassadin holds 43.3%.

The specific problems:

• Physical damage. Void Stone reduces magic damage only, and 89 armor at level 18 is the weakest part of Kassadin’s defensive profile.
• Explosive Charge. The bomb detonates after repeated attacks on the target, so trading autos with Tristana is worse than it looks at first glance.
• Buster Shot. A knockback interrupts the approach Riftwalk exists to create, and it can be held for exactly that purpose.

His counterplay begins at 6 and improves with every point of ability haste. Riftwalk’s rising mana cost punishes careless chaining, so the correct pattern is one teleport into Null Sphere and Nether Blade rather than three into a Rocket Jump. Kassadin’s 2,567 health at level 18 against her 2,374 means he survives a full rotation once items arrive, and Force Pulse’s cone slow keeps her inside range after she has spent the jump.
