Features

  • New Enemies:
  • Gast: Appears in the Crypts.
  • Banshee: A Meadows Mini Boss that can be summoned in the Crypts.

Hint-Spoilers (Click to expand)

Hints and Spoilers

  • Meadows Crypts:
  • Crypts have walls that are destroyable with a pickaxe or blunt weapon.
  • Crypts could also have a room that seems impossible to get across. There is a way, and there are stones to help you back up to the entrance if you fall.
  • The Banshee mini boss can be summoned in the crypts using the surtling core found in the same room.
  • Black Forest Caves: Both caves have the same shaped entrance. Cave 2 will need to have the ground leading into it mined away to access the gateway.
