Polymer Bundle Farming in Warframe (2026): Assur and Ophelia on Uranus
Uranus is the Polymer Bundle planet: Assur first, Ophelia second
Last Updated on September 30, 2026
The short answer
Go to Assur (Uranus), a Dark Sector Survival on a planet where nearly every resource drop is a Polymer Bundle. Run it with Nekros using Desecrate, or Hydroid with Pilfering Swarm, and a Resource Booster. Ophelia (Uranus) is the normal Survival alternative.

Every place it drops
Polymer Bundle drops on: Mercury, Venus, Uranus.
The fast route
- Load Assur (Uranus) and pick Survival. It is a Dark Sector.
- Slot a Resource Booster and a Resource Drop Chance Booster.
- Bring Nekros and hold Desecrate, or Hydroid holding enemies in Tentacle Swarm with Pilfering Swarm.
- Stay in one spot with a full squad so more enemies spawn.
- Extract when your count is met. Switch to Ophelia for a lower-level run.
Best farming frames
| Frame | Role | Why |
|---|---|---|
| Nekros | Loot roller | Desecrate rerolls corpse drop tables on a Survival. |
| Hydroid | Loot roller | Tentacle Swarm with Pilfering Swarm gives held enemies a chance at extra drops. |
| Khora | Loot roller | Strangledome with Pilfering Strangledome adds extra loot from held enemies. |
Tips that save runs
- Uranus is the best planet for Polymer Bundle, and Plastids drop there too.
- Break containers as you go. Ophelia has plenty of containers and crates.
- A companion with Loyal Retriever or Resourceful Retriever occasionally doubles a pickup.
Mistakes that waste runs
- Farming on Mercury or Venus once you can reach Uranus.
- Running Assur solo when a full squad spawns more enemies.
