How to Play This Matchup
Power Curve
Kassadin is strongest late game while Cassiopeia peaks late game. Play around your power window.
MR Priority
Both deal magic damage. An early Null-Magic Mantle or Mercury's Treads can swing the lane. Hexdrinker is also an option for AD champs.
Hit and Run
Kassadin needs to combo and back off. Don't stay in extended trades against Cassiopeia's sustained damage. Short trades, then disengage.
Range Advantage
Cassiopeia has range advantage. Kassadin should look for short trades when Cassiopeia uses abilities on the wave. Freeze near your tower and wait for jungle help or an all-in window.
Exploit Kassadin's Weakness
Kassadin's main weakness: Early game extremely weak, AD matchups, CC. Play around this to maximize your advantage.
Kassadin Win Condition
Survive to 16, R spam becomes uncatchable assassin
Cassiopeia Win Condition
E spam DPS, R stun if facing, no boots = more AP
