Swiftthistle
Swiftthistle is an uncommon herb, it can be found anywhere that Briarthorn and Mageroyal would grow. So to farm this herb it will be slightly harder than the average herb as it does not have its own independent nodes. Therefore to farm Swiftthistle, you’ll be running the same route as either Mageroyal or Brairthorn.
