Hawk
What it does: If you enter any square below a Hawk, and nothing is between you and it, it will swoop down and carry you to another room.
How to make it:
You can’t. It just is.
What it makes:
Hawks aren’t all hassle. You can merge three of them with a Flame Spirit to get a super-useful Potion of Movement.
Or you can throw one in with a Forest Shrine and make a Willowisp.
