resist to poison only useful if you don't have mead. cuz it's 50% that not stacks with mead's 75%.
i doubt it's worth using to actually fight monsters cuz you'll have way lower armor value even if you'll upgrade all pieces to lvl4.

on the other had it doesn't require any metal. so you can save some iron and use it to craft\upgrade more important stuff
