Slayers 2 Underwater Rocks: Where to Find Sea Crystals
The Underwater Rocks task in Slayers 2 (formerly Project Slayers 2) Water training means collecting five Sea Crystals. Follow the underwater objective and look for glowing blue pickups, including ledges close to the surface. The interaction says Sea Crystal / Pick Up even though the quest says Underwater Rocks. Collect until the counter reaches 5/5.

When the underwater objective becomes available
Water Breathing Training starts with Parkour Dungeon, Push ups, Boulder Push and Aim Training. Underwater Rocks is the next step; the Water Trainee remains locked until you finish collecting.
Read the tracker before diving. If the rocks row still has a prerequisite lock, return to the unfinished training task. Having reached the correct body of water does not advance an earlier exercise.
How to find the blue Sea Crystal pickups
- Follow the active Underwater Rocks marker after completing Aim Training.
- Inspect the underwater edges and ledges first, including the shallower spots near the surface.
- Approach a glowing blue object and read its Sea Crystal / Pick Up interaction.
- Use the pickup prompt and check that the Underwater Rocks counter increases.
- Continue along the ledges until the counter reaches 5/5, then follow the newly available Water Trainee objective.
Stuck at 4/5 or searching for ordinary rocks?
| What you see | What to do |
|---|---|
| You are looking for an item named Underwater Rock | Inspect glowing Sea Crystals; the task label and pickup name differ. |
| You have searched only the deepest floor | Sweep the shallower ledges and edges near the surface. |
| The counter remains at 4/5 | Search another ledge for a remaining blue pickup and verify the counter after collecting. |
| You are trying to carry rocks back to the trainer | Use the Sea Crystal pickup interaction. This objective counts collected items; follow the tracker after the fifth. |
After collecting all five
The next Water task is the trainee fight. Follow that objective rather than returning to Aim Training or repeating the underwater search.
After the complete training chain finishes, open M then Skill Tree and inspect the Water branch. The Sea Crystal task moves you toward the breathing unlock; individual moves still need their own nodes. Flowing Motion, if that is the ability you are searching for, belongs to the Tomioka clan route.
