Strategy

How to beat The Blackstone Sovereign

  • Fight in the open, away from walls and props, so you always have room to leave the warning shape.
  • Kite in wide circles: your skills keep firing while you move, the boss does not.
  • Clear the regular horde around the boss first; the fight is the boss, not the crowd.
  • Watch the phase marks on the boss health bar — each one is a moment to stay patient rather than greedy.

Skills that make this fight easier: Lightning, Phoenix, Frost Nova.
