Cost Analysis

Gold Value

Gold Efficiency

  • Tiamat is gold efficient even without its passive and active.



  • Cleave has a radius of ~385; Crescent has a radius of 400.[2]
    • Cleave is centered on the target; Crescent is centered on the user.
  • Activating Crescent does not reset the auto-attack timer. Rather, the effect uses the champion's auto attack animation to display the effect.
    • Crescent casts faster as you gain more attack speed.
  • This item shares the Cleave and Crescent effects with Ravenous Hydra.
  • This item's passive and active cannot be used by ranged champions.
  • Cleave's damage is based on the attack damage champion statistic, not from actual damage dealt on the attack—it therefore doesn't benefit from critical strikes or on-hit effects
  • Cleave from Tiamat does not trigger on-hit effects or life steal.
    • Cleave's and Crescent's damage procs The Black Cleaver's passive effect, which is not an on-hit.
  • Cleave will not trigger if it has triggered on a different target in the last 0.05 seconds.[3]
  •  Parrrley procs Tiamat as well as Ravenous Hydra despite the fact that the ability has a range.
    • Using  Gangplank's  Parrrley with Tiamat will give you extra gold for every single minion killed with Tiamat's passive effect.


  • In Babylonian mythology, Tiamat was the first dragon and was slain to make the heavens, earth, and man.
  • In the V1.0.0.115 April Fools day patch Tiamat was renamed to Tamat, the name of a Rioter.
  • Tiamat is also the name of the five headed dragon goddess in the Dungeons And Dragons RPG.
  • This item is very similar to the DotA item Battlefury : both requires 2 attack damage items and 2 regeneration items to build (althrough Battlefury have mana regeneration rather than a second health regeneration) and both gives area of effect damage on autoattack for melee only.
