The Legend of Zelda: Link's Awakening (2019 video game)/Dampé

Finding Dampé
Once the moblin cave is cleared, go east from the cave to find Dampé. Dampé introduces himself as a digger, and invites Link to his shack. Take him up on that offer and continue east to reach Dampé's shack.

Once the Bottle Grotto is complete, Dampé begins allowing Link to use the dungeon creator. Whenever Link clears a dungeon or gains a chamber stone, return to gain more building options.

Whenever Link completes a dungeon, the rupees from that dungeon are kept as a reward.

Using the Dungeon Creator
There are four options at Dampé's, but only three before the first dungeon is made.

Complete Dungeon Arranging 101, which starts out partially completed. This serves as a tutorial to the interface.

Complete the dungeon to earn a new chamber stone containing a room with bats and four blade traps. This new dungeon room has a south opening and an eastern opening.

Complete Placing the Basics to gain a new chamber stone.
