These are normally in a pack of two or more but can be found alone as well, TO TAME: Use a BOLA (point at the back legs just above ankles) to catch, once caught then punch it until it drops unconscious

Open inventory - put raw meat in, 6 or more

Wait for the tame to complete and there you go you have a saber

Note: THESE ARE NOT RIDEABLE WITHOUT A SADDLE!
