1. Can my mount critical hit? I've been playing a little and rolled a natural 20 during my horses attack. We weren't sure if my horse could crit (It didn't matter because I did the confirmation roll and couldn't crit anyway) but I wanted to be sure if, because the horse is my mount and is attacking with me, it could critical hit on a natural 20 or not (I'm assuming that if it can it's a 2x hit). I searched for this issue and haven't found anything on it.
2. Can my horses hooves both attack? The way both the druid page and bestiary write the attack (2 hooves) is the same way the attack for a giant crab (2 claws) is written. I fought a giant crab in one of the dungeons I was in and it was able to attack with both claws so am I able to do this also?
3. Can I attack with all of the attacks? My character hits (currently 1 hit as the bab is only 2) then my horse bites then hoof attack (or 2 if the question above turns out to be yes). I'm pretty sure I can attack with all attacks during my turn but just wanted to clarify.
4.Does my horse roll it's own initiative or go with mine? This hasn't caused any issues (the horse just went on my turn) but I wanted to make sure.
5. Is the 2-hooves attack attack a primary or secondary natural? The context is that my horse is combat trained (I did it pre-first dungeon). The two arguments are as follows:
1. 2-hooves becomes a primary attack. Combat training (also called war training) takes away the docile nature. The bestiary says,
"Docile (Ex) Unless specifically trained for combat (see the Handle Animal skill, a horse's hooves are treated as secondary attacks."
So therefore because I trained my horse for combat the 2-hooves attacks also becomes a primary attack (along with bite)
2. 2-hooves remains a secondary. Because the horse that a cavalier gets for a mount is clearly different from the one listed in the bestiary page we have to use everything from the druid page. The Druid page stated that 2-hooves is a secondary attack but doesn't give the docile nature to the horse. So, because it never had the docile nature even though it's combat trained it keeps the 2-hooves as a secondary attack (keeps it as written on the Druid page).
I've found a lot on this issue but nothing is conclusive so any help on this issue and the others would be appreciated.
