Karthus' Abilities

Guides Builds Counters Skins Abilities Q&A To Top

Death Defied Karthus's Passive

Self

Upon dying, Karthus enters a spirit form allowing him to continue casting spells for 7 seconds. During this time his abilities cost no mana.

Lay Waste Karthus's Q Ability

875

20 / 25 / 30 / 35 / 40

Karthus briefly reveals the target area which he detonates after a 0.5-second delay, dealing 45 / 62.5 / 80 / 97.5 / 115 (+35% of ability power) magic damage to all enemies within, doubled when hitting only one target.

Lay Waste's damage is reduced by 15% against monsters.

During Death Defied, Lay Waste will cast at maximum range if cast beyond that.

Wall of Pain Karthus's W Ability

1000

Karthus creates a 800 / 900 / 1000 / 1100 / 1200 distance wide wall at the target location for 5 seconds. The wall reduces the magic resistance of enemies who pass through it by 15% for 5 seconds and applies a 40 / 50 / 60 / 70 / 80% slow which drops to half effectiveness after 1 second and then decays over the remaining debuff duration.

Defile Karthus's E Ability

425

30 / 42 / 54 / 66 / 78

0.5

Passive: Karthus restores 20 / 27 / 34 / 41 / 48 mana whenever he kills an enemy.

Toggle: Drains 30 / 42 / 54 / 66 / 78 Mana every second. Deals 7.5 / 12.5 / 17.5 / 22.5 / 27.5 (+5% of ability power) magic damage every 0.25 seconds to all nearby enemies. Deactivating Defile deals 1 tick's worth of damage.

Defile cannot be toggled off during Death Defied, but it can be while channeling Requiem.

Requiem Karthus's Ultimate (R) Ability

Self

100

200 / 180 / 160 / 160 / 160

After channeling for 3 seconds, Karthus deals 200 / 350 / 500 (+75% of ability power) magic damage to all enemy champions (regardless of distance).
