Skull Cavern deep dives

Prepare for the infinite Skull Cavern: luck, bombs, staircases, and how to dive deep for iridium and Prismatic Shards.

  • Prepare for the infinite Skull Cavern: luck, bombs, staircases, and how to dive deep for iridium and Prismatic Shards.

Prepare before you go

Bring healing food, Mega Bombs (clear a 3x3), and 30-50 Staircases (99 Stone each). Eat Spicy Eel for luck and speed, and reach the cavern by 7-8am.

Luck is everything

Watch the TV fortune. Only deep-dive when the spirits are very happy or you have eaten luck food — lucky days spawn far more ladders and shafts.

Descend fast

Bombs clear rocks quickly and Staircases skip bad floors. Avoid fighting every monster — speed is the goal, not combat XP.

Loot & dangers

Iridium nodes are common past floor 40; the deeper you go the denser the loot. Treasure rooms may drop an Auto-Petter; Pepper Rex can drop Dinosaur Eggs. Passing out at 2am costs 1,000g.

  • Repair the Bus (Vault) to reach the Desert
  • Bring 30-50 Staircases + Mega Bombs
  • Eat Spicy Eel (luck + speed)
  • Check the TV fortune; dive on lucky days
