Complete Castbound Rod Mastery in Fisch by clearing every mastery quest, meeting the final rod and item requirements, and unlocking Copperbound rewards with permanent Castbound upgrades.
To complete Castbound Rod Mastery in Fisch, you need to own and use the Castbound Rod, finish the Anger, Like a Boss, and The Journey’s End mastery quests, then claim the Copperbound skin and permanent Castbound upgrades.
Castbound Rod Mastery is late-game work, not a quick beginner checklist. You are expected to already have Castbound, use it for the mastery tasks, and then clear a final ownership check involving several high-end rods or items.
The full mastery line has three quests: Anger, Like a Boss, and The Journey’s End. Finishing the line unlocks the Copperbound skin and permanent upgrades that make Castbound much stronger for long-term farming.

Requirement for Castbound Rod Mastery
To finish Castbound Rod Mastery, you must own Castbound, complete all three mastery quests, and claim the final mastery rewards. The rewards include the exclusive Copperbound skin plus permanent buffs such as more durability, more chances, a higher slash rate, and a stronger perfect-cast Fury bonus.
This is an end-game mastery path because the final quest asks you to own several expensive or progression-heavy rods and items. If you only just reached Castbound access, expect the mastery line to take time, event luck, and a lot of late-game collection work.
Before starting Castbound mastery
You need the Castbound Rod before any of this matters. Castbound is commonly tracked as a Stage 10 Fishing Rod tied to the Guide NPC at the Underground Music Venue, reached through the Depths, Crystal Cove, and the hidden venue area.
Current player reports commonly place Castbound behind a Level 1000 requirement and a task involving 10 shiny Flying Fish at night. Some players also report a disputed 15-rod ownership gate involving high-tier rods such as Rod of the Depths, Rod of the Forgotten Fang, Heaven’s Rod, Tempest Rod, Zeus Rod, Ethereal Prism Rod, Free Spirit Rod, Great Rod of Oscar, and Ruinous Oath, but that extra gate is not confirmed in every current account.
Castbound itself is already a high-end rod, with reported stats including infinite lure speed, 390% luck, 0.14 control, 32% resilience, infinite max kg, and 180m line distance. Its passive is also tied to mutation farming, which is why the mastery line leans so hard on Fury and perfect catches.
Quest list for Castbound mastery
| Quest | Objective | Where or how | Reward |
|---|---|---|---|
| Anger | Catch 50 Fury fish | Equip Castbound and fish across the map | Prisma Lantern |
| Like a Boss | Perfect-catch 3 Rotbloom | Rotbloom Hunt event near Toxic Grove | Gemidium Bobber |
| The Journey’s End | Own five high-end rods or items | Igneous Rupturer, Tidemourner, Verdant Oath, Wind Elemental, and Zeus’s Thundermaul | Copperbound skin and permanent upgrades |
Use this table as the clean map for the mastery line before you start grinding. The first two quests are active fishing tasks, while The Journey’s End is mostly an ownership check for specific late-game rods or items.
Anger quest: 50 Fury fish
Anger is the simplest Castbound mastery quest on paper: equip Castbound and keep fishing until you catch 50 Fury fish. The important part is that the catches need to come through Castbound’s passive behavior, so swapping to a different rod will slow or stop the relevant progress.
The exact Fury rate is still a little messy. Early mastery numbers list the ghost passive as a 25% chance to obtain the Fury mutation, while broader Castbound passive notes describe a 50% chance to gain another fish with one of several mutations, including Cosmos, Nebula, Energy, or Fury. Treat the exact rate as unsettled and solve the quest with volume: keep Castbound equipped and keep catching.

Like a Boss quest: 3 perfect Rotbloom catches
Like a Boss is stricter than Anger because it is not just asking for Rotbloom catches. You need 3 perfect catches of Rotbloom while using Castbound.
Rotbloom is an Exotic tier fish tied to the Rotbloom Hunt event, which can spawn near the Toxic Grove area. Some early captions and player chatter shorten or misspell the name as Rod Blooms, but the target fish for this mastery quest is Rotbloom.
For the cleaner setup, use Castbound with Luminous Larva and Thorn Cluster. The reward for clearing this quest is the Gemidium Bobber, but the real bottleneck is consistency: a non-perfect Rotbloom catch does not satisfy the stated mastery objective.
Do not swap rods during mastery; keep Castbound equipped for Fury rolls and Rotbloom perfect catches, because progress is tied to using that rod.
The Journey’s End quest: required rods and items
The Journey’s End is the largest Castbound mastery quest because it is not another normal fish grind. It checks whether you own five specific high-end rods or items: Igneous Rupturer, Tidemourner, Verdant Oath, Wind Elemental, and Zeus’s Thundermaul.
Some early listings use slightly different spellings, including Igneous Rupturer, Tide More, Verdant Oath, and Zeus’s Thundermaul Maul. The names below use the commonly reported item names, but if your server text or player notes use one of those variants, it is likely pointing to the same final-quest requirement.
- Igneous Rupturer: Reach Level 500, complete the Scoria Reach bestiary, then talk with Scoria Guard.
- Tidemourner: Craft it with 3 Tide Essence, 5 iron chunk, 1 Tidemourner head, and 1 worn moonstone.
- Verdant Oath: Complete the Toxic Grove, Living Garden, and Nectar Den bestiary, reach Level 1000, and spend 12,500,000 in-game currency.
- Wind Elemental: Reach Level 800 and complete the Wind Mastery’s quest.
- Zeus’s Thundermaul: Complete the Zeus’s Thundermaul of Chaos bestiary, unlock the gate, and spend 18,750,000 in-game currency.
Do not treat this quest like a secret catch requirement. If your progress is not moving, check your ownership of the five listed rods or items first, then check whether any spelling variant in your current build is referring to the same requirement.
Copperbound rewards and permanent upgrades
| Reward or upgrade | Effect |
|---|---|
| Copperbound skin | Exclusive mastery skin for Castbound. |
| +200 durability | Adds more durability to the mastered rod. |
| 3 more chances | Gives extra miss tolerance while fishing. |
| +50% slash rate | Boosts the rod’s slash rate after mastery. |
| Perfect-cast Fury enhancement | Perfect casts give +25% Fury base chance and +5 starting progress. |
| Toxic, lava, and brine pool usefulness | Players currently track the mastered rod as more useful in toxic, lava, and brine pool areas. |
Completing the full Castbound mastery line gives you the Copperbound skin and makes Castbound better as a long-term farming rod. The permanent upgrades are especially useful if you already use Castbound often for mutation farming, money-making, or late-game biome fishing.
The biggest practical change is that perfect casts become more rewarding. If you can already land them reliably, mastered Castbound becomes much better at pushing Fury-related value instead of only relying on the regular passive roll.
Mistakes that block Castbound mastery
The most common mistake is working on the quests without Castbound equipped. Anger and Like a Boss both depend on using the rod, so a better general-purpose rod can actually waste your time if it is not Castbound.
The second mistake is misunderstanding Like a Boss. You need perfect catches on Rotbloom, not just three normal Rotbloom catches, and the fish is tied to the Rotbloom Hunt event near Toxic Grove.
The final trap is assuming The Journey’s End asks you to catch one special fish. It is an ownership check for five specific rods or items, and older short-form clips may miss the updated wording, item spellings, or final reward details.
Next Castbound goals
After mastery, the natural follow-ups are the parts that feed into this grind: how to get Castbound, how to catch Rotbloom during the Rotbloom Hunt, and how to obtain Igneous Rupturer, Tidemourner, Verdant Oath, Wind Elemental, and Zeus’s Thundermaul.
If you already have the mastery finished, your next practical goal is tuning the rod around your farming style. A mastered Castbound setup is mainly about consistent perfect casts, Fury value, and money-making routes that take advantage of its mutation-focused passive.
Frequently Asked Questions
Do you need Castbound equipped for mastery progress?
Yes. You need to own Castbound first, and you should keep it equipped while working on the mastery quests. Anger depends on Fury catches with Castbound, and Like a Boss specifically requires perfect-catching Rotbloom with Castbound.
How do you get Fury fish for the Anger quest?
Equip Castbound and fish across the map until you get 50 Fury fish. Early mastery numbers put the Fury roll at 25%, while broader Castbound passive notes describe a 50% mutation-passive roll with Fury as one possible result, so the safest approach is to keep catching with Castbound until the quest completes.
Where does Rotbloom spawn for Like a Boss?
Rotbloom is tied to the Rotbloom Hunt event, which can spawn near Toxic Grove. For Like a Boss, you need 3 perfect catches of Rotbloom while using Castbound.
What rods or items are needed for The Journey’s End?
The Journey’s End requires ownership of Igneous Rupturer, Tidemourner, Verdant Oath, Wind Elemental, and Zeus’s Thundermaul. Some players may see slightly different spellings for these names, but those five are the commonly reported final-quest targets.
What do you get for completing Castbound Rod Mastery?
Completing Castbound Rod Mastery gives the Copperbound skin and permanent Castbound upgrades: +200 durability, 3 more chances, +50% slash rate, and a perfect-cast enhancement that adds +25% Fury base chance and +5 starting progress. The questline also gives earlier rewards such as the Prisma Lantern and Gemidium Bobber.
