I remember watching the Telescope die on its fifth charge as the anomaly flickered out—cold anger, followed by a quiet regret. You stand there with five wasted opportunities and a lab that seems a step ahead. I learned how to stop that from happening; here’s the fast route.
The lab’s fluorescent light buzzes down the hall — How to Make Reinforced Battery in Fisch
I’ve spent nights trading casts for parts so I could spare you the same headache. You need two things before you can craft a Reinforced Battery: all five Telescope lenses and the recipe from Dr. Crookspine. The lab sits to the right of Roslit Bay; use the Fisch GPS and punch in -1915, 225, -530 to get there faster.
Collect every lens, talk to Crookspine to obtain the recipe, then return to Astronomer Vega by the Telescope to craft. Click View Upgrades in the bottom-left of the screen and you’ll see the Reinforced Battery recipe ready once you have the parts.
| Material | Quantity |
|---|---|
| Scrap Metal | 1 |
| Battery Casing | 1 |
| Any Mythical Astral Observatory Fish | 1 |
| Enchant Relics | 3 |
How many uses does a Reinforced Battery have?
The Reinforced Battery gives you 20 charges compared to the standard battery’s 5. The Reinforced Battery is a Swiss watch of charges: steady, predictable, and built to last through far more anomaly triggers. When it drops to zero, you can recharge it with Enchant Relics at Astronomer Vega.
The shoreline is littered with rusted lines and tins — How to get Scrap Metal in Fisch
If you want Scrap Metal, fish any daytime body of water: Moosewood, the Mineshaft, or The Depths are reliable spots. Use the Garbage Rod with Garbage bait to force Trash-rarity catches and farm Scrap Metal consistently.
If you need mutated variants for crafting or quests, apply Cursed Touch or fish during Celestial events with rods like the Celestial or Starfall to pull in Cursed Touch Scrap Metal and Celestial Scrap Metal.
The Mineshaft mouth is always humid — Where to find Battery Casing in Fisch
Battery Casing is a Rare Find that drops only in the Mineshaft with a flat 1% chance. Rare Finds ignore rod luck and preferred bait, so focus on maximizing casts per minute instead of gambling on luck.
Use high lure-speed baits such as Beach Ball, Rapid Catcher, or Seaweed and pair them with a Scavenger-enchanted rod to cram as many casts as possible into each minute.
The caverns breathe a different light at night — How to catch Mythical Astral Observatory Fish
Mythical Astral Observatory fish appear in six hidden Astral caverns. For example, the Boreal Pines Astral Cavern hides the Aurora Gar under the frozen lake at 21875, 110, 4255 during a clear winter night. Other targets include Boreal Man o’ War, Comb Jelly, Cuttlefish, Golden Trout, and Fairy Penguin in their specific caverns.
Use high-luck stage-10 rods like Astraeus Serenade, Black Fairy, or Fabulous, and enchant them with Immortal, Mystical, or Divine to improve your odds. Once you have any Mythical Astral Observatory Fish, it counts toward the Reinforced Battery recipe.
How do you recharge a Reinforced Battery in Fisch?
You recharge a depleted Reinforced Battery by handing Enchant Relics to Astronomer Vega. Keep a small stock of three or more so you can top off the battery between anomaly runs and avoid wasted trips to Roslit Bay.
I’ve walked the Mineshaft, baited the same spot for hours, and traded lenses at midnight in Roblox servers—so you don’t have to learn the hard way. The lab is a lighthouse: it guides you, but you still have to climb the stairs. Will you stick with five charges and the old gamble, or build a battery that actually lasts? ?
