  • This Secret does not activate if the attacked minion already has Divine Shield.
  • Interaction with Noble Sacrifice: If the attacked minion does not have Divine Shield, it will summon a Defender then give the targeted minion Divine Shield. If a minion with Divine Shield is attacked and triggers Noble Sacrifice, the Defender gains Divine Shield.[1]
