The wolf chest piece gives you frost resistance making the wolf cape redundant.
Plus it looks goofy. Make it later to complete the set.
Frostner is fun but frost arrows do the same thing from a distance.
Where did you get the idea Plains critters are immune to frost? I think
Yagluth is but goblins/beserkers/shamans are not. You can one shot shamans
with frost arrows and slow down beserkers and kill them with 4 or 5 arrows.

electricdawn is right: make/upgrade the armor and shield. your iron club and
bow will do the job against wolves and drakes; golems can be a problem, if you
kill them they respawn so lead them into a trap they can't get out of or maybe
parry them off the mountain so they can't climb back up: no more golems

a lot of people like the silver sword and D Fang is the best bow to use for Moder
but not really necessary until then

you need some silver for a cauldron upgrade; don't forget that

you'll find LOTS of silver while looking for those elusive Frost caves
