I was taking Apolo to Darkshire a couple of days ago and we took the Gryphons to Sentinel Hill.
Apolomyth was following me, and after we landed, he stayed on the gryphon. He followed me down the road while still on the bird!
I asked if this was a warlock talent? He said, "What talent? What bird?"
He couldn't see the bird!
So, I took a picture.
Here we are almost to Darkshire and Apolomyth is still on the bird. He rode it the entire way. It was very cool. Wish I knew which glitch caused that to happen. I'd try it sometime.
