The damage dealt by this item is reactive damage.
Damage is reflected when hit by a basic 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.
By itself, Thornmail reflects at least 33 magic damage on being hit.
Healing effects triggering on a basic attack ( life steal, Udyr's Turtle Stance, Xin Zhao's Determination, etc.) will first be reduced by Grievous Wounds.
- This means that the Grievous Wounds, applied by Thornmail, will be effective with the basic attack that triggers the effect.
Warden's Mail, Thornmail, Frozen Heart, and Randuin's Omen are the only items that can reduce attack speed.
- The attack speed slow on Warden's Mail, Thornmail and Randuin's Omen do not stack with each other, however they do stack multiplicatively with Frozen Heart for a combined 27.75% attack speed slow.

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.

Thornmail is the only purchasable item in the basic tutorial.
Pentakill's first volume, Smite and Ignite, named its seventh track after this item.

Bug Fix: Now correctly applies the cripple debuff to minions and monsters attacking its owner.

New Recipe: Bramble Vest + Ruby Crystal + Warden's Mail + 400 = 2900
- Old Recipe: Cloth Armor + Chain Vest + 1250 = 2350
Armor reduced to 75 from 100.
New Effect: Grants 250 health.
Removed Passive: Reflects 15% of the physical damage taken (+ 25% bonus armor) from basic attacks and on-hit effects back to its source as magic damage.
New Passive – Thorns: Upon being hit by a basic attack, reflects magic damage equal to 25 (+ 10% bonus armor), inflicting Grievous Wounds on the attacker for 1 second.
New Passive – Cold Steel: When hit by basic attacks, reduced source's attack speed by 15% for 1 second.

Total cost increased to 2350 from 2100.
Reflected damage reduced to 15% from 30%.
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. Armor penetration will not affect the ratio.
