Horses, Running Fast, and Plowing Through a Crowd

[Spermy The Cat]

I'm building and fiddling with a Fell Rider Cavalier, and I got to say, they're pretty fun.
But I'm confused how to use the Overrun on them, namely who gets it.
I think it's the rider, and a friend helping me says it's the mount.
So give me a hand here, who takes the feats to crash into people?

By logic, the one moving is the horse, not the rider, that is only a passenger, so it is the horse that overruns the people.

On the other hand, the text of the Trample feat and of the Rampage ability can read either way.

For sure it is the rider that receives the trample feat.

It is the usual problem with all the stuff about riding, most of the time it is written as the rider and the mount was the same entity.

Trample

Ride 1 rank, Mounted Combat.

Benefit: When you attempt to overrun an opponent while mounted, your target may not choose to avoid you. Your mount may make one hoof attack against any target you knock down, gaining the standard +4 bonus on attack rolls against prone targets.

Yeah, the Trample feat is pretty clear: while mounted, your mount

But then...if your mount has a better CMB than you and has it's own agency, could you just hang on while your mount makes it's own Overrun attempt?

Well crap.

Mount gets it, meaning that Rampage is bugged for bonuses.
Guess I owe my friend a Coke.
Show's over folks.
Honestly, this should be a FAQ.
