Probably ^^
Or I would still try and find some secret route...
or who knows, perhaps we can actually climb

Accually I have my fingers crossed on climbing. My logic?? Well it's confirmed we can duel weild any combo of one hand weapons/spells/ sheilds right? That means left hand/right hand control. So if you have empty hands, and cliff, just right hand to hand hold, swing body via mouse, time it right then left hand to hand hold repeat process until top of cliff or you miss a handhold and fall big time.
Seems only logical to include given that if they are incorporating seperate hand control.
Then again, I just got into my skumma.
