I know it might sound silly, but can a level 5 mount take Vicious Stomp if it took the prereques?
Can a Horse Mount take Imp. Unarmed?
Was thinking of Trampling for an attack and then having my mount V Stomp the target after.
Ah. So then level 8 minimum by the time it can get it.
Thanks friend.
I would point out, mounts usually benefit from Improved Unarmed Strike just by virtue of having natural attacks, so you wouldn't be getting anything out of that feat. If I were running this, I would waive the IUS requirement for a creature with a natural attack. That isn't RAW obviously, but unless this is PFS, I would talk to the GM about house-ruling it. Not much of a stretch really, but that's just my two copper.
Mounts totally benefit from IUS--it lets them take full, iterative attacks and tack on their natural weapons as secondaries. It's awesome for animals to have.
