## How to Play Karthus

Champion-specific pre-match tips

### Lane Phase

Position your Q slightly behind the enemy champion, ensuring it misses the minion wave to trigger the double isolation damage.

### Lane Phase

Last hit minions using auto-attacks or single-target Qs while your E is toggled off to trigger its passive mana restore.

### Lane Phase

Pan your camera to side lanes immediately upon reaching level 6 to look for an ult cast from under your tower, ensuring the long channel cannot be interrupted.

### Mid Game

Cast W across narrow jungle chokepoints before a skirmish to shred enemy magic resist and slow targets for guaranteed Q hits.

### Mid Game

Cast Q twice while your E burns after dying in a skirmish, then immediately channel your ult during the final three seconds of your passive.

### Mid Game

Toggle E off the moment you finish clearing a wave or objective to avoid draining your mana pool before the next fight breaks out.

### Late Game

Flash directly onto the enemy backline with E active during objective standoffs, forcing them to either concede space or kill you and fight inside your passive zone.

### Late Game

Channel your ult from a safe distance just before a major objective fight begins to force the enemy team to contest with a massive health disadvantage.

### Late Game

Place your W across the objective pit entrance when the monster drops below 3000 health to slow incoming enemies and zone them off the steal.

### Draft Context

- Lacks a frontline or peel — Karthus gets dove with no protection between them and the enemy
