I've been tangling with a mounted Summoner build for a while, and I'm having trouble parsing feats that the Summoner herself can take and how they affect an Eidolon being used as a mount.
My main question is, can the Summoner use the Ride check provided by the Mounted Combat feat to avoid an attack on their Eidolon? Mounted Combat reads:
Once per round when your mount is hit in combat, you may attempt a Ride check (as an immediate action) to negate the hit. The hit is negated if your Ride check result is greater than the opponent’s attack roll.
The Mount evolution is simply described with
An eidolon is properly skilled and formed to serve as a combat-trained mount. [size restriction text omitted]
So my understanding of this situation is that, as per having the Mount evolution, the eidolon counts as a mount, and thus qualifies the Summoner to be able to protect them using the Ride check offered by Mounted Combat. Is this correct?
