Crystal Obstacles are stages in Build A Boat For Treasure. It will replace all the rocks with black colored rocks with crystals jutting out of them. It has a roof, unlike most other obstacles.
If staying long enough or a player is out of a seat, lasers from multiple crystals will lock onto the player and kill them. The lasers on the walls no longer activate.
- This stage takes the longest time to load compared to the other stages because is is so long with many crystals that need to be formed. Although unlikely, this can lead to some boats falling off the sides of the stage on a new server.
