Nothing really big for this story.
I just didn't like how 5e's Owlbear was just a grey bear with an owl's face.
So I thought I would try to draw up a better on. scaly protection on the claws, new big owl tail, and then keep the rest the same.
This was pretty fun to make for me because I got to look up owl feather patterns for the new colors, far better stuff than just a gray body with a white face.
