* Blue/Water upgrade Quest / Shoot blue vase in bedroom area with wonder weapon. Vase will break revealing wisp. Shoot wisp and wisp will move location. Head to spawn area where wisp will move from boat to boat. Shoot all locations to retrieve blue Crystal.
- Wisps are located at bridge area near spawn, look out into water from bridge and shoot wisp (there is also boat location out into the water opposite the fizz machine in ice cave area)
