  • This skill inflicts half damage against boss monsters.
  • While the damage can be blocked by Pneuma, the chance to break armor remains.
  • Kyrie Eleison and Guard block both the damage and the chance of breaking armor.
  • When the armor break occurs, the affected entity will display the "/omg" emote.
    • Depending the server, that doesn't automatically mean they had their armor broken; even when using Chemical Protection or wearing an Immortal armor, the /omg will display itself so long as the attack was considered a success.
  • The damage is increased via ATK cards, and status cards have no effect.
