Yea that is weird... lets see how it plays out and maybe we will houserule it next time...
Also with Corwin's Aid, Hunter (or anyone else) can gain Advantage on your roll and your DC is reduced to 10. Only one person a round can climb this way...
Waiting for one one reply also...
That's why I think it's backwards. Of the mount is forced to move its a check not to fall off, if the mount is knocked over, your guaranteed to land on your feet unless you've used your reaction. I would have done it the other way is all.Well this is fantasy and all so i guess it works. All i know is that irl it's rare for a horse to fall over w.o the rider going down as well. best you could do is hope to land right and roll to your feet, but you'd have to see the fall coming.
