  • Includes boss encounters such as the Decaying King in the Nether ruins of a lost kingdom, the Old Champion???s Remains in a grave structure, and the Returning Knight, whose projectiles bounce off him.
  • Takes inspiration from RPG-style armaments, with some weapons noted as similar in spirit to equipment from games like Lineage 2.
