Rot Garden: cost, levels and upgrades

Short answer

The Rot Garden grows biomass for binding and hunting, and timber for building, in one plot.

What it does

A Rot Garden makes biomass and timber every hour. Biomass feeds the Binding Pit and hunting parties; timber goes into every building and gate.

Its paths lean one way or the other: fungal beds for more biomass or a timber grove for more timber at level 3, and a seed vault or blight farm at level 5.

Specialization paths

At levels 3 and 5 an upgrade asks you to pick one of two paths. The choice is permanent.

LevelSpecialization pathsEffect
3Fungal Beds30 % more biomass.
3Timber Grove50 % more timber.
5Seed VaultStores 150 more of every material and 10 more serum.
5Blight Farm40 % more biomass, but the rot draws hordes: extra noise.

Tips

  • If your horde is growing slowly, you're usually short on biomass before serum. A second Rot Garden fixes it.
  • Pick Timber Grove if you're expanding and upgrading gates; pick Fungal Beds if you bind and hunt a lot.
  • Blight Farm makes the most biomass but is loud. Pair it with a quiet village elsewhere.

Questions

How much does the Rot Garden cost in Voxhorde?

Building it costs 20 scrap, 25 timber and takes 2 min. The first upgrade, to level 2, costs 35 scrap, 45 timber and takes 4 min.

What is the Rot Garden's max level?

Level 10. Levels past 2 need island expansions: level 3 needs 2 and level 5 needs 3. Levels 6 to 10 also need a league reached at least once: Iron for 6, Steel for 7, Chrome for 8 and Warlord for 9 and 10.

Numbers come straight from the game's rules and update with every release.
