Cost Analysis

Gold Value

  • 100 armor = 2000 Gold
    • Total Gold Value = 2000 Gold

Gold Efficiency

  • Thornmail item.png Thornmail is 95.2% gold efficient.
  • For the item to be gold efficient, its passive must have a value of at least 100 Gold.


  • On being hit, Thornmail will reflect 30% of the physical damage dealt by the attacker, including most on-hit effects.
  • Damage is reflected when hit by an attack, regardless of whether the attack deals damage. If the attacker is blinded, or the wearer is protected by a shield or invulnerability, damage will still be reflected.
    • Abilities that apply on-hit effects, such as Blade Waltz.png Blade Waltz, will trigger Thormail.
  • If you have >233.3 effective armor, Thornmail will reflect more damage than you receive, assuming the attacker has 0 magic resist; if they have 30 magic resist, >333.3 armor is required.


  • Thornmail is a particularly effective defensive option when facing down opponents whose damage is dealt primarily through autoattacks, or against opponents that utilize on-hit healing to survive fights (such as life steal).
  • Unlike Molten Shield.png Molten Shield and Defensive Ball Curl.png Defensive Ball Curl, Thornmail's magic damage does not trigger spell effects.


  • It is the only purchasable item in the tutorial.
  • Currently, this item offers the largest amount of armor along with Frozen Heart item.png Frozen Heart.
