Ars Gouda location and Bestiary unlock guide
The short answer: travel south in Dairy Plant and collect Ars Gouda
Item | Details |
|---|---|
Relic | Ars Gouda |
Stage | Dairy Plant |
Direction | South of the starting point |
Marker | Green guide arrow while uncollected |
Unlock | Bestiary in the main menu |
Ars Gouda is south of the starting point in Dairy Plant. Follow the green guide arrow while the relic is uncollected, then touch it to unlock the Bestiary in the main menu.
How to get Ars Gouda
- Reach level 40 in Inlaid Library to unlock Dairy Plant.
- Enter Dairy Plant.
- Build enough early damage near the starting point.
- Follow the green guide arrow south.
- Touch Ars Gouda to collect it.
- After the run, check the main menu for the Bestiary.
Dairy Plant also contains the Milky Way Map. Both relics are south of the starting area, so do not assume the first pickup completes both objectives. Check the pause map or the remaining guide arrow before ending the run.
What Ars Gouda unlocks
The Bestiary records information about enemies you have defeated. It is useful when an unlock condition asks you to defeat a certain enemy a set number of times.
Collecting Ars Gouda does not automatically reveal every enemy. Blank entries still require you to encounter the relevant enemy in play.
