Climb

You jog to the top of the hill, hoping to spot the approaching sound first. Unfortunately, what produced the sound arrived at the exact same time, and spotted you! It is a large centaur, at least seven feet high and even longer. It’s lower half is that of a clysdale, covered in saddle bags, while it’s upper half is that of a large muscular woman. Wearing only straps of leather as a makeshift harness barely covering her cleavage and preventing them from flying with each gallop, she carries a long spear and a net, both weapons that would be of great use on the plains. While startled by you, she hasn’t attacked yet. You could try to talk, or just try for initiative and attack the large creature.
