Oak
What it does: Just kinda sits there and stares at you. Kinda eerie, really. It’s also a common door-opening item.
How to make it:
They grow all by themselves and somehow don’t lose their leaves in the winter.
What it makes:
Take an Ax to the Oak to grab a piece of Wood.
It also merges with a Heavy Rock and the Ancient Mortar to make a Stone Seed.
