High Five

NecrobinderAttackUncommon
Osty deals 11 damage
and applies 2 Vulnerable
to ALL enemies.
  • Hit: Osty throws the punch, so the 11 damage uses his attack bonuses such as Calcify rather than your Strength, and it hits every enemy.
  • Vulnerable: then you apply 2 of it to all enemies.
  • Requirement: the card is only playable while Osty is on the field and glows red when he is missing.
  • Interaction: the hit counts as an Osty attack, so Bone Flute gives Block and Sic 'Em's Summon triggers on its enemy.
  • Upgrade: 13 damage and 3 Vulnerable.

When to take High Five

Take it for multi-enemy fights: one of the few ways the Necrobinder applies Vulnerable to a whole group. Only pick it when Osty stays up reliably, through Bodyguard, Spur or Invoke.
