Thornmail is an advanced item in League of Legends.[1] Tanks benefit most from it, when the opposing team has high basic attack damage output. League of Legends calculates Thornmail's reflected damage before armor reduces the damage. This means you can reflect more damage than you ultimately take[2] if you have at least 234 effective armor (i.e. after reductions and penetration).[3] Thornmail deals magic damage, and so the target's magic resistance will reduce it.

Recipe

Strategy

  • Thornmail Thornmail is best used to counter champions that mainly rely on basic attacks such as Tryndamere Tryndamere and Ashe Ashe.
  • Thornmail Thornmail is not valued as highly as the other two high armor items, Frozen Heart Frozen Heart and Randuin's Omen Randuin's Omen, because it protects only the wearer instead of the entire team.
    • It is still a cheap item to counter many champions and should be considered not only by tanks.

Notes

  • Thornmail Thornmail reflects both physical and magic damage; the only determining factor in its trigger is whether the attack is defined as proccing on-hit effects. For example, Warwick's Warwick's Infinite Duress Infinite Duress deals only magic damage, but still procs Thornmail's Thornmail's unique passive.
    • The damage reflection works with basic attacks and skills which apply on-hit effects, but not with any damage resulting from on-hit effects (e.g. damage from Madred's Bloodrazor Madred's Bloodrazor).
  • Blind counts as a form of damage mitigation and is thus applied after Thornmail Thornmail, i.e. damage is still reflected even though none is actually done. It is important to note that life steal, however, is not applied while blinded.
  • Damage returned from Thornmail Thornmail will break passives which are removed by champion damage such as Move Quick Move Quick, Strut Strut, and Boots of Mobility Boots of Mobility. It will also drag tower aggro.

Trivia

  • It is one of the few items mentioned in The Proving Grounds tutorial.
  • Currently, this item offers the largest amount of armor, being slightly above Frozen Heart's Frozen Heart's 99 armor.
