The Wild at Heart

In order to purchase upgrades at The Grove, you first need to collect the Water Wheel. The Water Wheel is located in the north-east corner of the Central Deep Woods, and you should be able to reach it relatively early on in your playthrough.

Once you've collected the Water Wheel and returned it to The Grove, you can construct the Fabricator, and from there start purchasing upgrades. Upgrades require the in-game currency and heartroot resin.

In-game currency isn't a problem - just sell either bloom stones or mesmerite to Crow's Nest. You'll find far more of these on your journey than you'll ever need.

Heartroot resin, however, is more difficult. There are a limited number in the game, and to unlock everything, you need to complete every side quest and unlock every chest in the game, as well as a couple of other things.

Here is how to get every piece of heartroot resin:

- Unlock all chests
- Complete the Grove Trove side quest (Scrap Heap)
- Complete the Bounties side quest (Toothpicks)
- Complete the Lost Cats side quest (Litterbox)
- Buy 2 from Cath in Crystalfall Coast
- Trade 3 bloom stones with Rubbish (located in north Central Deep Woods)

If you need help locating chests or quest items, buy the Compass from Cath and give it to Paper Planes in The Grove. Sleep and return to Paper Planes, and he will give you a fixed compass which shows the location of every hidden item on the map.
