The Mariana’s Veil update in Fisch has introduced thrilling new depths to explore, but accessing them requires a key tool: the drill. This powerful device lets players break through tough rock formations to gather critical resources like submarine components and rare crystals. Whether you’re building your first submarine or upgrading for deeper dives, knowing how to acquire and wield the drill is essential for progression.
Navigating to Roslit Bay: Your Starting Point
Roslit Bay serves as the gateway to this update’s content. Located east of central areas like Moosewood Village, it’s easily reachable by boat. Launch from any dock, set your course eastward, and look for the bay’s distinctive shores marked by construction sites and rocky outcrops.
- Launch your boat from a nearby village dock.
- Steer east across the map until you spot Roslit Bay’s lighthouse and submarine frame.
- Dock carefully to avoid obstacles, then head northwest along the shoreline.
Once arrived, the area buzzes with activity—unfinished submarines dot the landscape, hinting at the quests ahead. This location isn’t just a pit stop; it’s where your deep-sea adventures truly begin.
Meeting Dr. Glimmerfin: Acquiring the Drill
At the heart of Roslit Bay’s construction zone stands Dr. Glimmerfin, the NPC who hands out the drill. Positioned near the incomplete submarine toward the northwest side, he’s easy to spot amid the scaffolding. Approach and initiate dialogue to kick off the submarine-building questline.
The conversation with Dr. Glimmerfin is straightforward but informative. He explains the need for specific parts scattered in nearby obsidian rocks. Upon completing the initial chat, the drill automatically appears in your inventory—no crafting or payment required. Check your backpack at the screen’s bottom to confirm it’s there.
| Step | Action | Outcome |
|---|---|---|
| 1 | Locate Dr. Glimmerfin near submarine | Start quest dialogue |
| 2 | Complete conversation | Drill added to inventory |
| 3 | Open backpack | Equip drill for use |
This free tool is a game-changer, enabling resource extraction that’s impossible with standard fishing gear.
Equipping and Basic Operation of the Drill
Using the drill is intuitive. Open your inventory via the bottom screen icon, select the drill, and it equips to your hands. Approach any minable rock—obsidian formations glow subtly to indicate they’re drillable. Left-click (or tap on mobile) to strike; each hit chips away at the rock’s durability.
Rocks typically require about 10 strikes to fully break, yielding potential loot. Not every attempt guarantees items, so persistence pays off. Formations respawn over time, allowing repeated farming without depleting the area.
- Equip: Inventory > Select drill.
- Mine: Click rock repeatedly (8-12 hits average).
- Collect: Loot drops automatically upon destruction.
Practice on initial obsidian clusters near Dr. Glimmerfin to get the rhythm down before tackling larger hauls.
Gathering Submarine Parts: The Core Quest
The drill’s primary purpose early on is collecting watercraft parts for your submarine. Obsidian rocks along Roslit Bay’s shores have a roughly 5% drop rate for components like windows, hull pieces, and engines. Target clusters marked by quest indicators for best efficiency.
Multiple parts are needed—typically 5-7 unique ones. Drill systematically: break outer rocks first, then inner ones as they expose. Parts stack in your inventory until ready for assembly. Once all are gathered, interact with the submarine frame to attach them automatically.
Pro Tip: Farm in groups. Rocks respawn quickly, so cycle through spots rather than exhausting one area.
Advanced Drilling: Crystals and Deep-Sea Upgrades
Beyond the submarine, the drill unlocks further progression. In Volcanic Vents—the first Mariana’s Veil layer—target lava rocks for Lava Crystals. These upgrade your craft for heat resistance.
Deeper still, Challenger’s Deep features ice formations yielding Ice Crystals for cold endurance. Each layer demands precise drilling amid environmental hazards, making the tool indispensable for full exploration.
| Location | Target Rock | Reward | Purpose |
|---|---|---|---|
| Roslit Bay | Obsidian | Watercraft Parts | Build submarine |
| Volcanic Vents | Lava Rocks | Lava Crystal | Heat upgrade |
| Challenger’s Deep | Ice Formations | Ice Crystal | Cold upgrade |
These resources enable traversal of extreme biomes, revealing exclusive fish and treasures.
Optimization Strategies for Efficient Mining
To maximize yields, focus on high-density rock areas. In Roslit Bay, northwest shores offer prime obsidian veins. Use your boat to ferry parts quickly back to the submarine site, minimizing travel time.
Group play speeds things up—friends can drill while you assemble. Monitor respawn timers (about 1-2 minutes per rock) and rotate spots. Avoid server crashes mid-farm by saving progress frequently.
- Prioritize quest-marked rocks for higher drop chances.
- Farm in 10-15 minute bursts to beat respawns.
- Combine with fishing breaks to maintain energy.
Advanced players experiment with drill angles for faster breaks, though base mechanics remain consistent.
Common Pitfalls and Troubleshooting
New users often struggle with equipping the drill—double-check inventory selection. Rocks not breaking? Ensure you’re targeting the glowing core, not outer debris. Low drop rates frustrate; remember the 5% odds and keep grinding.
Server instability can interrupt quests—rejoin and speak to Dr. Glimmerfin again if parts vanish. Mobile players: use precise taps to avoid misclicks.
Drill’s Role in the Bigger Fisch Ecosystem
The drill bridges surface fishing with abyssal hunts. Post-submarine, it facilitates rare material farming for rods, outfits, and baits exclusive to Mariana’s Veil. Mastering it opens high-value fishing spots teeming with unique species.
Future updates may expand its uses, but currently, it’s pivotal for endgame content. Track patch notes for enhancements.
