Damage Heal (Alt: Recovery Conversion) is a supportive buff skill exclusive to monsters.

For 30 seconds, a specific type of damage dealt to the monster will be converted to heal it instead.

• Your attacks will miss and the monster will be healed.

• Clearance will remove this effect, but Dispell does not.
• Once it shows the monster is healing, stop attacking and wait 30 seconds for effect to stop.
• Use a different type of attack to damage it if available.
