Atlanticore

The Atlanticore (AC) is a Legendary Hero, and is a Tank-class Hero with melee attacks. His Skill Spectacular Scales makes him invincible to all damage and reflects all incoming damage back at the source(troops only) for a short period of time. The Atlanticore is a heavy-duty tank comparable to the Paladin, with only slightly less HP. Although he has the slowest ATK speed of all the current Heroes, (one attack per 2 seconds,) his skill may be one of the most powerful, both defensively and offensively. When paired with the Revitalize or Berserk Talent, the Atlanticore truly shines at his best in all aspects of the game.
Atlanticore won't reflect any damage when he's under the effect of Guardian Angel
