Hello everyone! Drewdafowl here! I found you the BEST way to grind these on fjordur. First go to the beach of the orange leafed island (bring a insane melee argy) and use a cross bow of those sea scorpions from far when you hit it run (or swim whatever) then jump on the argy when they get close the argy has a larger attak range and insane knock back so just keep whacking them when it dies get of argy whack with metal pick mastercraft is best and boom! infinite chitin and silica pearls! Hope this works for you to! Your welcome.
