The Allu'thoa Front

Steps
1. Leash any deino that has "earthshaker" in its name with the item in your bags or from the Quest Helper. This makes it non aggressive, and you can do this while it is attacking to stop the fight.

2. Go to the Pygmy Bridge (/loc needed)  and simply stand there while the deino catches up to you, and then attacks the Allu'thoa
