I'll make some buckets, what should I do after I get the skill?
Remove a sign from the south corner, as I said before, and then call down the thunder to the one nearest to the south corner. Get 21 IP, then go a little close to the Auroch. When he moves to attempt an attack, do a sidestep when he fails. Complete three sidesteps and then use sting like a bee. One you have done that, you may quell it.
Now, after you have gotten 20 Taming points, lose aggressiveness with the Auroches, then come back and call down the thunder on a different member of the herd. After you complete a call down the thunder, you can now call down on the main one you are trying to tame. So, you repeat the process until you reach 100 Taming points.
