Shearpoint is guarded by a dragon who can be killed like any other dragon by either lowering the difficulty and tanking the damage or seeking cover and gradually shooting him out of the sky with a bow and arrow.
It is also guarded by Krosis who has huge amounts of health and can cause a lot of damage on hard difficulties. You can either lower the difficulty or you can attack him until your health is low and then hide behind a tree or some stones or a small heap of dirt and recover your health by using potions, magic or the natural health regeneration. The latter is very slow though so it might make you very bored.
