Its actually pretty easy to dodge a drake's attack (right click and hold then press the space bar, works even better if you are moving sideways rather than forward or back) and once it has missed it takes several second before it is ready to make another pass so the drakes are not an issue. There are a couple of other things you can do about the wolf.

Set a portal up near the base of the mountain so you can return quickly from your main base or portal hub. If you can find a nearby troll even better. Sleep if it is night time, craft a flint spear, eat all the highest stamina foods you have available, get your rested bonus, the only thing you should have in inventory is the spear and a frost mead.

Portal over, drink the mead, when you get near your body and the wolf go into sneak mode until you are in range to throw your spear (middle mouse). Then throw the spear to get the wolf's attention, (this also empties your inventory) activate the Eikhytr power and sprint away from your corpse. If you found a troll lead the wolf to the troll and while the wolf and troll try to kill each other you can circle back around to your corpse. When the wolf is on your heels and is about to strike use the rolling dodge maneuver. If you didn't find a troll keep sprinting until you run out of stamina and let the wolf kill you again.

Grab a frost mead, eat, rest and portal back. Go 90 degrees from the direction you led the wolf away and walk 100 or so meters that direction before climbing up the mountain again so that once you are near you corpse you are approaching it from a 90 degree different angle. When you get near it enter sneak mode again and check for the wolf. If hasn't returned go and grab your corpse and gear. If it has returned keep circling around so that you approach your corpse from directly opposite it. The wolf should be far enough away that you can sneak right up to within grabbing distance of your corpse without alerting it.

If grabbing your corpse alerts it equip your belt first if you are overloaded, then equip your shield and block the first attack. Equip your weapon and block the 2nd attack then swing once, block the next attack and swing once, repeat until you've killed the wolf and can take the time to equip the rest of your gear.
