How to Get Undead Fishman in Legacy Piece

Equip Fishman and talk to the Fishman Elder on Fishman Island. Complete the Undead Fishman quest, gather the evolution materials, and return to the Elder for the race unlock.

Undead Fishman is a quest-linked race, so treating it as an ordinary reroll target misses the main route. Start by checking the race actually equipped on your character. Then choose the matching evolution objective at the Elder before farming its items. Quest progress and the final material collection are separate checkpoints.

The current race card supplies both the opening objective and the turn-in list. Use it alongside the material cards when deciding what to farm next. If you already have Fishman, preserve it while you work through this route. Changing races for a general tier recommendation before the unlock can remove the named prerequisite you still need.

Fishman to Ancient Fishman and Undead Fishman

Fishman, Ancient Fishman, and Undead Fishman belong to quest-linked progression. The Undead Fishman card names base Fishman as its prerequisite; it does not list Ancient Fishman as a required earlier stage.

That distinction matters when planning a farm. Do not assume the three names form one mandatory sequence just because they appear together in a race roster. Read the evolution you want and select its own quest. The Ancient Fishman and Undead Fishman materials have similar names, but an Ancient Scale is not an Undead Scale.

If you searched for the Ancient Fishman race in Legacy Piece while trying to unlock Undead Fishman, check which destination you intended. The names identify different race entries. A guide about one evolution should not become the material checklist for the other. Use the Elder's active objective and your inventory labels to keep them apart.

Undead Fishman Requirements

The opening quest asks for five Fishman Captain defeats and three Undead Fishman Scales. The final evolution uses 20 Undead Fishman Scales, five Undead Fishman Cores, 100 Dreadtide Fangs, and 50 Dreadtide Hearts.

Talk to the Elder with Fishman equipped before building your farming plan. The Scale reference ties drops to accepting the Undead quest, and the Core reference places its drops after quest completion. This makes the order important: first open the route, then complete the initial objective, then finish the later collection.

Scales and Cores are linked to Fishman Captain, while the Dreadtide material cards identify Dreadtide Revenant as their source. Focus on the missing item rather than repeating whichever boss you fought most recently. Check the relevant material card and active stage when a farm is not producing the item you need.

What Undead Fishman Does for a Build

The race card lists lifesteal, damage bonus, HP regeneration, and damage reduction. Its Undying Depths passive adds Soul shards and a conditional survival effect.

The listed base effects are 12% lifesteal, 15% damage bonus, 6 HP regeneration per second, and 15% damage reduction. Undying Depths has three Soul shards, each adding 8% lifesteal. With all three present, a lethal blow shatters them and restores 25% of maximum HP; a shattered shard returns every 45 seconds.

Those effects make sustain and repeated fight completion useful reasons to consider the race. Test how often you can finish a rotation and recover between dangerous attacks. A survival effect is conditional, so do not plan every encounter as if it were always available. Watch the shard state and keep a defensive option for a bad opening.

Do Not Reroll a Quest-Linked Fishman Race Too Early

Keep the Fishman prerequisite while working on the evolution. A reroll changes the race you are relying on for this unlock.

Before spending a Race Reroll, check whether the next objective still names your equipped race. A general damage recommendation is less useful if changing to it interrupts the quest you are trying to finish. Complete the planned unlock first, then decide whether another race suits your long-term build.

Do not rely on a code reward as a guaranteed way to recover the same race afterward. Reroll resources help you make another attempt; they do not replace an evolution quest or promise a particular result. Keep the codes guide separate from your route checklist so a resource claim does not become an assumption about unlock completion.

Common Undead Fishman Unlock Problems

Check the equipped race, chosen evolution quest, five-Captain counter, and exact material names before repeating the farm.

If the Elder does not offer the expected route, inspect the equipped race and current quest stage. If the counter is unfinished, focus on eligible Fishman Captain defeats and the quest's Undead Scales. If the Core is missing, finish the opening quest and then use its material reference rather than assuming every earlier kill could supply it.

If the final exchange is unavailable, compare all four material totals with your inventory. Look carefully for Ancient versus Undead names, and for Fang versus Heart. One full stack does not compensate for another missing ingredient. Return to the Elder after the collection is ready rather than treating a completed opening quest as the final reward.

Frequently Asked Questions

How do I get Undead Fishman in Legacy Piece?

Equip Fishman, talk to Fishman Elder on Fishman Island, complete the Undead quest, gather its evolution materials, and return to the Elder for the unlock.

Can I get Undead Fishman with ordinary race rerolls?

Treat it as a quest-linked evolution rather than a normal reroll target. The route names Fishman as its starting race and has a quest and material exchange.

Do I need Ancient Fishman before Undead Fishman?

The current Undead Fishman card requires base Fishman. It does not list Ancient Fishman as a prerequisite, so follow the Undead objective rather than assuming a mandatory three-race sequence.

What materials does the evolution need?

The final collection is 20 Undead Fishman Scales, five Undead Fishman Cores, 100 Dreadtide Fangs, and 50 Dreadtide Hearts. Complete the opening quest before the final exchange.

What does the Undead Fishman race do?

It supplies lifesteal, damage bonus, HP regeneration, and damage reduction. Undying Depths adds Soul shards with a conditional lethal-hit survival effect.

Should I reroll Fishman while doing the quest?

Keep the required race while completing the route. Check the active objective before changing races so you do not remove the prerequisite for your planned unlock.
