SFS Standard Mount Feat 5

Prerequisites Large size or larger

You are proud to serve as a mount for your trusted allies. This might be a natural development, or it might be the result of intense training to ensure you can operate as a mount for your allies.
When another PC rides you as a mount, your expert coordination allows them to gain three actions at the start of their turn rather than the two they normally would for riding another PC (page 11). You still gain only two actions at the start of your turn instead of three, however, as you spend the third action keeping your ally balanced on your back and ensuring they're firmly mounted.

Option(s): quadrupedal posture only
