Notes

Item VFX

• Thorns deals reactive damage, and thus will not trigger spell effects.
• Thorns is not blocked by spell shield.
• Thorns' reflect is not a projectile.
• 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 16 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.

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.
