Order of the Beast (The Advanced Class Guide one) Question

[177cheese]

The order in question:

Now, the order's ability Wild Shape Mount basically says "You can transform your mount with beastshape".

My question is this,

If you give up your mount via an archetype but gain an animal companion through another means (feat, multiclass, etc), would that animal companion be a viable target of the ability as your mount? Or does the ability mean specifically your mount from the mount class feature?

I don't think it'd be unreasonable to gain a horse companion from the Animal Ally feat, take the Daring Champion archetype and the Order of the Beast to be a duelist on the back of a dragon, but I want to make sure its valid as written.

This isn't for PFS, just for clarification. Thank you.

I'd say no. Cavalier mounts are like super bonded to their Cavaliers. More so than Druids to their pets or well, Wizards to their familiars. If your mount as a cavalier dies you need s full week to replace it, and a full level before it regains several abilities. Animal companions just need 24 hours and they are back to full strength. That would be my game, your dm may say the 2 feat investment is enough for it to count.

Oh phone so can't correctly link the Druid vs. Cavalier dead animal companion penalties.
