Notes

• Damage is reflected when hit by a basic attack, regardless of whether the attack deals damage. If the attacker is Template:Cctip, or the wearer is protected by a shield or invulnerability, damage will still be reflected.
• By itself, Thornmail reflects at least 25 magic damage on being hit.

Strategy

• Thornmail is a particularly effective defensive option when facing down opponents whose damage is dealt primarily through basic attacks, or against opponents that utilize on-hit healing to survive fights (such as life steal).
• Unlike Molten Shield and Defensive Ball Curl, Thornmail's magic damage does not trigger spell effects.
• Damage dealt by Thornmail is considered single-target for the purpose of Omnivore.

Trivia

• Thornmail is the only purchasable item in the tutorial.
• Currently, Thornmail offers the largest amount of armor from a single item.

• New Effect: Reflected damage now deals (+25% bonus armor) bonus damage.
  • The armor ratio will be affected by flat armor reductions down to 0 armor - while percent armor reductions will be ignored for the purpose of calculating bonus damage.i.e. The Black Cleaver will not reduce the reflected damage by reducing your bonus armor but a level 5 Puncturing Taunt will reduce the reflected damage by 6.25(25% of 25).Negative armor values will be treated as 0.
