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 22 magic damage​​ on being hit.

Strategy

• Thornmail is most effective against enemies that use basic attacks to deal damage and attack at a fast rate.
  • It is also useful against enemies that heal through their attacks.
