Hints and Spoilers
- Meadows Crypts:
Crypts could have walls that are destroyable with a pickaxe.
Crypts could have a room that seems impossible to get across. There is a way, and there are stones to help you back up to the entrance.
- Black Forest Caves: Both caves have the same shaped entrance. Cave 2 will need to have the ground leading into it mined away to access the gateway.
