Notes

• Thorns deals reactive damage, and thus will not trigger spell effects.
• Thorns is not blocked by spell shield.
• Thorns' reflect is not a projectile.
• Thorns will trigger regardless of if the basic attack deals damage or not.
  • This includes if the user mitigates all damage with a shield or invulnerability.
  • It will not trigger if the attack is dodged, blocked, or missed while the attacker is blinded.
• Heals that trigger on-hit will take place after Thorns' Grievous Wounds has been applied.
• By itself, Thornmail's Thorns reflects at least 16 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  healing from attacks to survive fights (such as  life steal).
• Unlike Molten Shield and Defensive Ball Curl, Thornmail's magic damage does not trigger spell effects.
