I never had much issues gathering enough frost glands, but then I only use it for Eyescream. ;)

Edit: Just a thought that occurred to me... The OP might not be using the right weapon when dealing with wolves. Axes no longer cut it after the swamp. They're way too slow.

I personally found wolves pretty manageable when using the Atgeir. I actually think that the Atgeir is by far the best weapon ingame.

My latest character Gudrun is roaming the plains and climbing the mountains in... Root gear, and so far I've survived. Thanks to the Atgeir, which can keep mobs at range.
