Complete Graveyard Keeper 2 Research Tree unlocks and how to get them

Graveyard Keeper 2 is now out, and with it arrives an expanded Research Tree. Divided into different categories, you’ll have to unlock the nodes to improve your graveyard. Completing the nodes require specific resources, but they grant you with additional supplies.

Disclaimer: I have included Building and Smithing on this guide. The rest will have their separate guides. Additionally, the rest of the categories have to be unlocked.
