Bug Fables Wiki

Cave of Trials is a setup for the team to earn berries, medals and items through fighting numerous waves of regular enemies. Enemies that Team Snakemouth hasn't seen yet will be displayed as silhouettes and rewards less Exploration Points than they are supposed to. Team Snakemouth can choose whether to heal up every 10 rounds (2 heals in total) or directly quit the trial, but they cannot change their layout once the trial begins. No healing option is available after round 50. Like in B.O.S.S., losing in the trial or running away on any round will not cause a Game Over, but instead just ends the trial, and berries and other rewards are given to Team Snakemouth according to how well they've performed.

It is found in Bugaria Outskirts, on the way to the Lost Sands. Placing the Mysterious Piece inside the cave and then showing the holographic Roach the Explorer Permit will open the system, and Team Snakemouth can use it afterwards as they wish. A Venus' Bud and a saving crystal can also be found in the room.

  • Leaving a trial will keep all your items, but will not heal you, unlike B.O.S.S.
  • This area is similar to the Pit of 100 Trials in Paper Mario series, except that there are no enemy drops, and a defeat will not cause a Game Over.
