Karthus is a powerful AP mage jungler known for his global presence and sustained damage output. His unique passive allows him to continue casting abilities after death, making him exceptionally dangerous in team fights.

Core Strengths:

  • Global map presence with ultimate (Requiem)
  • High sustained damage output
  • Strong AP scaling
  • Excellent team fight potential
  • Post-death damage contribution

Ability Priority:

  1. Q (Lay Waste)
  2. E (Defile)
  3. W (Wall of Pain)
  4. R (Requiem)

Optimal Skill Order: Level 1-3: Q > E > Q (for safe farming) Alternative Level 3: W (if early fighting expected) Max Order: Q > E > W

Starting Items:

  • Dark Seal + Refillable Potion
  • Alternative: Doran's Ring + Health Potion

Core Build:

  1. Liandry's Anguish
  2. Sorcerer's Shoes
  3. Shadowflame
  4. Rabadon's Deathcap
  5. Void Staff
  6. Zhonya's Hourglass

Runes: Primary (Domination):

  • Dark Harvest
  • Cheap Shot
  • Eyeball Collection
  • Ultimate Hunter

Secondary (Precision):

  • Presence of Mind
  • Last Stand

Jungle Pathing:

  • Start Red Buff
  • Full clear focusing on single target Q damage
  • Aim to reach level 6 quickly for global pressure

Key Strategies:

  • Position Q to hit single targets for double damage
  • Use E for clearing small camp monsters
  • Place W strategically to slow enemies and reduce magic resistance
  • Save ultimate for securing kills or assisting other lanes
  • In teamfights, position safely and utilize passive when needed

Best Team Compositions:

  • Excels in AD-heavy teams as the primary AP threat
  • Works well with engage-heavy teammates
  • Strong with teams that can lock down enemies

This champion particularly shines when played as the sole AP damage source in AD-heavy team compositions, maximizing damage output when enemies build primarily armor.
