If your Collections tab refuses to hit the final Conjurations total even though most world regions show 100%, check your Vivariums next. These 12 hidden chests live inside your own animal habitats, not out in the Highlands, so many completionists forget them until the very end.

Quick Answer

There are 12 Vivarium Collection Chests total — 3 in each Vivarium biome. They do not appear on the World Map chest counter, so they are one of the biggest reasons players get stuck at 128/140 or 139/140 Conjurations. Use the 4-tab biome map below, then sweep each Vivarium from the portal outward so you do not miss a chest tucked behind a cave, ruin or cliff.

Location descriptions in this planning aid are approximate landmarks, not verified pixel-accurate map pins. Confirm each chest with Revelio and the in-game layout.

Why these chests matter

Vivarium chests reward random Conjurations, but unlike hamlet chests and many open-world trackers, they sit outside the World Map counter. That means you can look "done" almost everywhere and still be missing several furniture or décor unlocks.

  • They are permanent once collected.
  • They are split evenly: 3 per biome.
  • You can grab them in any order.
  • If you are at 139/140 Conjurations, these 12 should be one of your first checks.
Easy rule: every time you unlock a new Vivarium, do a full left-to-right sweep immediately instead of saving them all for the endgame.

Biome-by-biome routes

Forest Vivarium

Use the big glowing tree as your anchor. One chest sits near the left cave, one near the upper ruins, and one is easiest to reach by following the waterfall path.

Coastal Vivarium

The Coastal biome spreads vertically, so work from the beach upward. Check every side path around cliff tunnels and sea-facing ledges.

Swamp Vivarium

The Swamp hides chests in dark, low-contrast corners. Use Revelio often and don’t stop after clearing the obvious bridge path.

Mountain / Grassland Vivarium

This biome has the cleanest sightlines, but one chest often gets missed because it sits behind a rear boulder route rather than on the visible main trail.

Best route & checklist

  1. Enter each Vivarium and move clockwise.
  2. Use Revelio at every major landmark: cave mouth, arch, cliff edge and waterfall.
  3. Collect all 3 before leaving that biome.
  4. If your Conjurations total is still short, check Butterfly Chests and Hamlet Collection Chests next.

FAQ

Do Vivarium chests count on the World Map?

No. That is why they are so easy to miss during 100% cleanup.

Can I get duplicate Conjurations?

No duplicate reward should be wasted — if a chest is unopened, it still has a real Collection reward waiting.

Which Vivarium gets missed the most?

The Swamp and Coastal Vivariums usually cause the most misses because their chests hide behind cave turns and cliff paths.

What should I check after all 12 are open?

Butterfly Chests, side-quest rewards and any remaining highlands or hamlet Collection Chests.
