To get an Obsidian Pearl in Fisch, catch Lava Clams in the lava at Scoria Reach. Each Lava Clam you catch gives you one random pearl, and the Obsidian Pearl is one of four possible results, with about a 1.5% chance per catch. Fisch is a fishing game on Roblox, and Scoria Reach is a hot volcanic island, so you'll want to prepare before you start casting.
| Pearl | Rarity | Chance per Lava Clam |
|---|---|---|
| Ashy Pearl | Common | 75.19% |
| Sulfur Pearl | Unusual | 22.56% |
| Obsidian Pearl | Mythical | 1.50% |
| Igneous Pearl | Exotic | 0.75% |
Getting to Scoria Reach From Moosewood
Scoria Reach is a separate island, so you'll need a boat to get there. The trip starts in Moosewood and runs east.
- Start in Moosewood and talk to the Shipwright NPC to spawn your boat.
- Head straight east.
- Enter Scoria Reach Island.
Gearing Up for Heat and Lava Fishing in Scoria Reach
Once you arrive, a small bar appears on the right side of your character. That bar tracks your body temperature, which rises while you're on the island. When it fills, you start taking damage, so heat is the first thing to plan for.
Scoria Armor helps you manage that heat. It costs 75,000 C$, and you need to complete 20% of the Scoria Reach Bestiary before you can buy it.
Your rod matters too. Fishing in lava needs a rod that's set up for it, and the Invincible enchantment is one way to get there.
Where to Catch Lava Clams in Scoria Reach
Lava Clams are a Rare fish, and you can catch them anywhere in the lava across Scoria Reach. You don't need to wait for a specific time to start fishing.
If you want a focused spot, open your Fish Radar and look for the Lava Clam pool opposite Ashbrook Town, at coordinates -5102, 162, -1177. Lava Clams move slowly and steadily across the bar, so they're easy to land once they bite, even though they're rare.
Obsidian Pearl Drop Odds, Bait, and Fishing Season
Every Lava Clam you catch gives you one random pearl from the table above. Because the Obsidian Pearl is a low-odds result, no set number of catches guarantees one, so expect a longer session. Keep the other pearls too, since you'll need them for the Igneous Altar.
Coal bait and Spring season help with bites. Lava Clams prefer Coal bait, and fishing during Spring raises your chances of catching one. Both affect how often a Lava Clam bites, not the pearl roll after you've caught one.
Using Obsidian Pearls With Crab Miners in Scoria Mines
Obsidian Pearls are used with the Crab Miners in the Scoria Reach Mines. You reach the mines through the elevator at -4972, 145, -1577, and you'll find Crab Miners roaming the area once you're inside.
- Give your pearls to a Crab Miner.
- Wait five minutes while the Crab Miner mines ore around the cave.
- Talk to the Crab Miner to collect your random rewards.
The rewards can include the fragment that matches the pearls you gave. An Obsidian Pearl improves your chance of an Obsidian Fragment, but it doesn't guarantee one. That fragment is one of the three the Igneous Altar needs, so this step is where your Obsidian Pearl feeds into the altar's progress.
