Off With Its Head

Objective
Guard the head of a Hydra on the path to Gran Soren.

Details
Harpies are on the path. You can also kick the ox with B if you are on the Xbox 360 or O (Circle) if you are on the PS3 to make him move faster at the cost of a bit of its health. If your attacks hit the Oxen then it will not injure it; however, if you were to throw something at it then it will lose its health. The oxen has a health bar, and when all of his health is gone you will not fail the quest because it is a main quest. He will stop until healed or all enemies around him are killed, and will move considerably slower. You can use Anodyne to heal the Oxen.

Walkthrough
Start at the waycastle, follow the cart, kill Harpies on the way, and some goblins, and you are at Gran Soren. Half way through you will need to open a gate. Also, beware of falling rocks atop of the hills. They can be triggered to fall early if you are a strider, by shooting the rock with a bow and arrow.

Another strategy is to run ahead of the caravan, and clear out any opposing threats. Then return to the caravan, can continue along the path without having to worry about the people or cart take any damage.
