Arc Raiders Familiar Duck Farming Guide — Bird City 105,000 RC Per Stack
Quick Answer
Familiar Duck sells for 7,000 RC per item and stacks to 15, making a full stack worth 105,000 RC — one of the most valuable inventory slots in the game. Only spawns during the Bird City map condition on Buried City, found in bird nests inside chimneys. South buildings with tall roofs and the small village near the center on the west side have the highest chimney density.
Step-by-Step Guide
What Is the Familiar Duck?
The Familiar Duck is an Epic-rarity trinket in Arc Raiders worth 7,000 RC per item. It has a stack size of 15, meaning a full stack sells for 105,000 RC — making it one of the most valuable single inventory slots in the game. It weighs 0.3kg per item so a full stack is 4.5kg. It can also be thrown to create a noise distraction for ARC machines, but given the sell value, throwing them is rarely worth it. Like all trinkets it cannot be used in crafting.
When and Where It Spawns
Familiar Duck only spawns during the Bird City map condition on Buried City. It does not appear during normal raids and cannot be found in standard containers or ground loot. When Bird City is active it adds three simultaneous modifiers: increased bird populations, more trinket spawns across the map, and additional ziplines connecting rooftops — use the ziplines to move between buildings quickly. Check the map condition screen before queuing and only run Buried City when Bird City is active.
How to Find Them — The Chimney Method
During Bird City, Familiar Ducks spawn inside bird nests which appear in chimneys across the rooftops. Community reports indicate south buildings with tall roofs and the west-side village have high chimney density. Exact spawn rates are not officially published. Climb to roof level and approach each chimney looking for an interaction prompt. Some angles are awkward so circle the opening if the prompt does not appear immediately. Not every chimney will have a nest — this is normal, keep moving to the next one.
Best Farming Strategy
Run multiple short raids during Bird City rather than one long raid. Each run focus exclusively on rooftop chimneys — ignore other loot unless it's also high value. Use the extra ziplines Bird City adds to cover rooftops faster. Extract as soon as your Familiar Duck slots are filled or you've covered all reachable chimney spawns. Bird City runs on a rotating schedule so plan your sessions around active windows.
Stacking and Selling
Pro tip: If you farm multiple Bird City runs, hold onto partial Familiar Duck stacks in your stash until you hit 15. Then sell the full stack via the vendor interface in Speranza for 105,000 RC in one go. (Trinkets can be sold to any trader in Speranza — no specific NPC required.) Bring a hatch key for faster extraction rather than the elevator when carrying a full inventory of valuable ducks. Do not throw them mid-raid as a distraction unless absolutely necessary — the RC value is too high to waste.
The Duplication Exploit — What You Need to Know
Embark confirmed a duplication exploit fix in Patch 1.25.0. While community reports link this to Familiar Duck, no official statement specifies the affected item. The three-strike ban system remains in effect.

Pro Tips
- ▸Check the map condition screen before every queue — only run Buried City when Bird City is active.
- ▸A full stack of 15 Familiar Ducks weighs 4.5kg and sells for 105,000 RC — exceptional value per kg.
- ▸South buildings with tall roofs and the small west-side village have the highest chimney density — prioritise these.
- ▸Bird City adds extra ziplines between rooftops — use them to cover chimneys faster rather than climbing from ground level.
- ▸Run light loadouts during Bird City farms — you want maximum carry capacity for ducks.
- ▸Bring a hatch key for faster extraction when carrying a full inventory of high-value ducks.
- ▸Snap Hook (14,000 RC) and Matriarch Reactor (13,000 RC) are higher single-item values but far harder to obtain consistently.
