Structures
MiniMods adds around twenty buildable structures. They fall into four groups: things that produce resources, things that serve your followers, the Strange Energy grid, and the two structures you use to set up your next run.
Run preparation
These two structures are where a run is decided before you ever enter a door.
Infernal Infuser

Replaces the Relic Infuser, which was removed in v1.3.0.
- Removed: select one relic to bring into your next run.
- New: select any amount of Trials and Augments to increase the difficulty of your next run.
Full effect list on the Trial of the Gods page.
Wishing Well II
![]()
The long-awaited wishing well is back and improved. With the help of Strange Materials it is fully powered, and lets you prepare for the most daunting challenges ahead.
- Removed: pay 20 gold and select one out of two cards.
- New: at no cost, select any amount of tarot cards from the vanilla and custom pool, plus a relic, to bring into your next run.
- Tarot effects no longer apply while you are in the base.
Production
| Structure | What it does |
|---|---|
| AIO Quarry | Select from 10 different types of materials to collect and a follower mines it for you. Left click to collect, right click to set the material |
| AIO Incubator | Choose from several plants to farm and a follower farms the one you select |
| Bone Mines | Followers mine bones here. Lasts indefinitely |
| Silk Mines | Followers mine silk here. Lasts indefinitely |
| Crystal Mines | Followers mine crystals here. Lasts indefinitely |
| Tree of Giving | Followers work here to generate small and medium gifts |
| Fishing Hut II | The custom replacement for the vanilla Fishing Hut, used by the Fisher role. Each hut stores up to 75 fish |
| Food Storage I & II | Store additional food to prevent it rotting |

Since v1.1.3, items from the mines and the AIO Quarry can be collected much faster, and followers stand to the side of a mine rather than on top of it so you can still interact with the deposit.
Follower services
| Structure | What it does |
|---|---|
| Waiter Desk | Build one and your followers start serving food to other followers, and collect food from the Follower Kitchen. Build one per waiter you want, anywhere you like |
| Sous Chef Desk | Select 1 of 10 dishes for the Sous Chef to cook. No more manually queueing meals |
| Follower Management Device | Spy on your followers and assign work commands remotely |
| Endless Pit of Gluttony | Dead followers can be buried here an unlimited number of times. Only the Reaper can bury them this way - the player currently cannot |
| Alchemy Cauldron | Select a necklace to create, then play a minigame. Succeed with no failures and the necklace is yours |
| Study Table | Where the Scholar works. See the Study role |
| Telescope | Where the Astrologer works. See the Astrologer role |
| Lucky Narinder Statue | For devoting to Narinder. Narinder himself can devote to it to instantly level up |

The Waiter Desk and the Sous Chef Desk act as role proxies: the corresponding role only exists if the desk is built, and followers then take the role up naturally.
Strange Energy grid

| Structure | What it does |
|---|---|
| Strange Generator | Converts Strange Material plus gold into Strange Energy |
| Energy Controller | Transfers energy from generators to the structures that use energy. Currently it draws from the Endless Pit and the Strange Generator |
| Stasis Chamber | Uses 50 Strange Energy to freeze time. While you are in base with time frozen it drains 10 Strange Energy per real minute |
See Items for where Strange Material and Strange Energy come from.
Later additions
The reference list above reflects the structures documented in the mod's own feature list. The changelog records further structures added in later compatibility releases - the Boutique in v1.2.2, for example - which are not yet covered by that list.
