Viktor vs Cassiopeia

Updated Jun 1, 2026

Overview

Viktor is a scaling control mage who must manage Cassiopeia's mid-range sustained damage and poison application.
Maintain medium lane pressure to prevent Cassiopeia from comfortably extending trades and applying poison.

Trading pattern

Trade by poking with E and shielding with Q, keeping W ready to disengage if Cassiopeia tries to commit.
Punish Cassiopeia when she misses Cassiopeia Q to reduce her poison uptime and E damage.
Avoid extended trades if Cassiopeia has W available to ground mobility or R ready to stun facing Viktor.

Danger windows

Viktor is vulnerable when W is down, as he lacks mobility and escape options.
Cassiopeia's R poses a lethal threat if Viktor faces her during all-ins post level 6.
Avoid extended trades when Cassiopeia has Cassiopeia W available to ground or slow Viktor's movement.

Early game

Focus on farming safely with E poke while avoiding Cassiopeia's poison application to limit her E damage.
Use Q shield proactively to mitigate damage when Cassiopeia commits to trades.
Avoid prolonged trades before level 6 to reduce risk from Cassiopeia's sustained DPS and R stun threat.

Power spikes

Viktor's major spikes are level 6 R and first completed item with evolved abilities.
Cassiopeia's major spikes are level 6 Cassiopeia R and first mana/AP item.
Respect Cassiopeia's level 6 spike by playing cautiously around her R stun window.

Win conditions

Scale safely through early levels to evolve abilities and complete core items for strong zone control.
Use W to control space and punish Cassiopeia when she mispositions or wastes Cassiopeia W.
Deny Cassiopeia extended trades by poking with E and shielding with Q, preventing her from applying sustained poison damage.
