Unleash

NecrobinderAttackBasic
Osty deals 6 damage.
Deals additional damage equal to Osty's current HP.
  • A Necrobinder starter: Osty attacks for 6 damage, 9 upgraded, plus his current HP.
  • Osty arrives with 1 HP and every Summon adds that much to him, so the card grows with the deck's summoning.
  • Example: with Osty at 5 HP it is an 11 damage card.
  • Because Osty deals the damage, his own buffs apply rather than yours.
  • If Osty is missing the card glows red and does nothing when played.

When to take Unleash

Keep it early, since its value tracks Osty's HP and it grows the moment Reanimate lands. Upgrade it if Osty stays big, and remove it if the deck stops summoning.
