Key takeaways
- Offering order. Wrong order consumes the item. This is the number one wasted hour.
- Carrying offerings in storage. The altar only reads carried inventory.
- Starting the ritual at dawn. If the server clock rolls into daylight mid-hold, the ritual fails and the key is still consumed. Start with at least two in-game hours of night to spare.
- Farming the Relic Shard. It is tradeable. Farming it is the least efficient step in the whole chain.
- Assuming it replaces a rod. It occupies a tool slot and does nothing for your cast. Budget your inventory accordingly.
The Sword of Darkness in Fisch is a quest reward from the Cursed Tide chain at Forsaken Shores — you cannot buy it, trade for it, or fish it up directly. You need Fishing Level 75, one Cursed Key pulled from a Sunken Chest in The Depths, and three offerings (a Dark Scale, a Cursed Eel, and a Relic Shard) placed on the altar inside the flooded cave north of the shipwreck. A prepared solo player finishes the chain in roughly 45–70 minutes; a group splitting the offering runs cuts that to about 25 minutes.
Note on numbers: the Cursed Tide chain has been rebalanced more than once, so treat the values below as the current-patch baseline and confirm anything that costs you real time in the in-game codex before you commit.
What the Sword of Darkness actually is
It is a melee utility item, not a rod. It does not cast, it does not add a fishing line, and it will not replace your main rod. What it does is open Cursed Chests without a key charge, cut Kelp Walls that block two routes inside The Depths, and — per the game’s official patch notes — grant a small nighttime luck modifier while it is equipped in your tool slot. If you are chasing it purely for catch rates, you will be disappointed; if you are chasing it to stop buying keys and to open the Kelp Wall shortcuts, it pays for itself quickly.
Unlock conditions at a glance
| Requirement | Value | Source | Can it be skipped? |
|---|---|---|---|
| Fishing Level | 75 | Levelling through normal catches | No — hard gate on the altar interaction |
| Cursed Key | 1 | Sunken Chests in The Depths (roughly 1 in 12 chests) | No — consumed by the altar |
| Dark Scale | 1 | Night fishing at Forsaken Shores | No |
| Cursed Eel | 1 | Mushgrove Swamp, fog weather preferred | No |
| Relic Shard | 1 | Any Sunken Chest, or barter with another player | Yes — tradeable |
| In-game time | Night | Server clock | No — the altar is inert in daylight |
Where the altar is
Forsaken Shores, north side. From the main dock, follow the shoreline north past the second shipwreck until the cliff face narrows into a flooded cave mouth at water level. Swim in, surface at the first air pocket, and the altar sits on the raised rock shelf on your right. The entrance is easy to miss because the waterline covers it at high tide — if you cannot see the cave mouth, wait for the tide to drop rather than swimming the whole cliff looking for another way in.
The fastest acquisition route, step by step
- Confirm your level first. If you are under 75, nothing else in this guide matters. The altar will not respond and you will have wasted a key. Grind to 75 before you spend anything.
- Farm The Depths for a Cursed Key — do this before the offerings. The key is the only truly random drop in the chain, so it is the long pole. Everything else can be bought or traded. Run Sunken Chests until one drops; bring a full bait stack so you are not sailing back to restock.
- Buy or barter the Relic Shard instead of farming it. This is the single biggest time save in the chain. A shard is tradeable, and paying market rate for it costs far less than the hour of chest-hunting it would take to find one yourself.
- Catch the Cursed Eel at Mushgrove Swamp during fog. Fog is the difference between a common night and a long one. Check the forecast before you sail; if there is no fog coming, do the Dark Scale first and come back.
- Catch the Dark Scale at Forsaken Shores at night. You will already be at Forsaken Shores for the altar, so pair these two steps and save a trip. Fish the deep side of the dock, not the shallows.
- Sail to the altar at nightfall with all three offerings plus the key in your inventory. Do not carry them in a chest or a storage slot — the altar reads your carried inventory only.
- Place the offerings in the order the altar prompts. Scale, then Eel, then Shard. The order matters; placing the Shard first consumes it and forces you to re-farm it, which is the most common way players lose an hour.
- Insert the key and hold the interaction. The ritual takes about ten seconds of uninterrupted hold. Any movement cancels it and consumes nothing — you can retry as many times as you like, so there is no reason to panic.
Required items, cost, and cheaper alternatives
| Item | Typical cost if bought | Cheaper alternative | Time if you farm it yourself |
|---|---|---|---|
| Cursed Key | Mid-tier market price; varies by server | None — farm only | 20–40 min |
| Dark Scale | Low market price | Farm at night, no bait needed | 10–20 min |
| Cursed Eel | Low–mid market price | Wait for fog rather than buying | 15–35 min (weather-dependent) |
| Relic Shard | Mid market price | Barter with a player running The Depths | 25–50 min |
Route comparison: what each approach really costs you
| Approach | Realistic total time | Coin outlay | Best for |
|---|---|---|---|
| Full solo farm, no purchases | 70–145 min | Near zero | Players saving coins |
| Solo, buy the Shard only | 45–70 min | Modest | Most players — best time-to-coin ratio |
| Buy everything tradeable | 25–35 min | Highest | Players with coins and little playtime |
| Group of 2–3 splitting runs | 20–30 min | Low | Friends online at the same time |
The two multipliers that matter most are fog for the Cursed Eel and darkness for the Dark Scale. Everything else in the chain is deterministic. If you plan the run around a fog window, you can comfortably land under 45 minutes solo.
Common mistakes and what the chain actually costs you
- Offering order. Wrong order consumes the item. This is the number one wasted hour.
- Carrying offerings in storage. The altar only reads carried inventory.
- Starting the ritual at dawn. If the server clock rolls into daylight mid-hold, the ritual fails and the key is still consumed. Start with at least two in-game hours of night to spare.
- Farming the Relic Shard. It is tradeable. Farming it is the least efficient step in the whole chain.
- Assuming it replaces a rod. It occupies a tool slot and does nothing for your cast. Budget your inventory accordingly.
On ownership realities: the offerings and the key are consumables and are gone whether the ritual succeeds or fails, so there is no “practice run.” The sword itself has no durability bar and does not need repairs, but it is account-bound once claimed — it cannot be resold, which means there is no reason to rush the chain for market value. Claim it when you are ready to use it.
Frequently Asked Questions
Can you get the Sword of Darkness without the Cursed Key?
No. The key is the hard gate on the altar interaction, and it is consumed when you insert it. There is no alternative route, no shop purchase, and no trade path to the sword itself — only the key and the offerings are tradeable.
Is the Sword of Darkness tradeable or resellable?
No. Once claimed, it is bound to your account. That is worth knowing before you buy a Relic Shard at a high price, because there is no resale value to recover the cost.
What happens if the ritual fails?
You lose the Cursed Key and any offerings already placed, but you keep the sword’s eligibility — the altar simply resets and you can start the chain again. Movement cancels the hold without consuming anything, so the only real risk is starting too close to dawn.
Do I need Fishing Level 75 exactly, or does it scale?
The altar checks for a fixed level, currently 75, and does not scale with gear or rods. Level is earned through ordinary catches, so there is no shortcut around it.
How long does the whole chain take for a first-timer?
Realistically two to three hours if you farm everything yourself and hit bad weather. With a bought Relic Shard and a fog window for the Cursed Eel, most players land between 45 and 70 minutes.
Is the Sword of Darkness worth getting in 2026?
Yes, if you run The Depths regularly — the free Cursed Chest openings and Kelp Wall shortcuts add up fast. If you mostly fish open water, it is a collection item and you should not spend coins on the offerings to rush it.
