Built for The Catch grind and spot cooldowns — not a fake map of every pond in Teyvat. Track the three refinement fish, mark ponds for ~72h respawns, and look up bait / day-night for the fish that matter.
The Catch refinement. Check Bishui / Dihua / estuary spots.
The Catch refinement. Same Liyue routes as Rusty Koi.
Bottleneck fish. One main spot east of the Tatarasuna / shipwreck area. Night only (18:00–06:00). Co-op helps.
Mark a spot after you clear it. Timer is ~72 real hours — changing the in-game clock does not refresh stock. Day/night still matters for which fish appear.
Time: Night 18:00–06:00
Time: Night for Snowstrider / Venomspine
Time: Day 06:00–18:00
Time: Day 06:00–18:00
