Serpent Form

SilentPowerRare
Whenever you play a card, deal 4 damage to a random enemy.

After each card you play finishes resolving, a random enemy takes 4 damage, 6 upgraded.

  • Direct: not an Attack, so Strength, Vigor and the enemy's Vulnerable do not change it, though Block absorbs it as usual.
  • Timing: the power remembers the stack count at the moment each card was played, so a card already mid-play when the power lands does not trigger.
  • New copy: playing a second copy deals damage at the old amount for that one play, then two copies mean 8 per card.
