str or dex on barb?

str
dex gear is cheaper tho, so if you're getting more dex than you would str for the same cost might as well get the dex

i have a 20 str charm and a 16 str charm

should i do dex then?

only the main charm stats will be active

charms in the acc slot wont give any stats

wat dose the acc slot do?

acc slot will make a charm work at 75% and all the stats it gives Excluding Ee will not be active

only real use for acc charm is to cast with

and since your a barb, it got no real use
