These guys are really great for getting chitin and killing broodmother. They have a passive damage boost against bugs and when they kill a bug they get another insane dmg boost making it great for killing broodmother.
It's great at collecting berries, fiber and chitin from insects/bugs. He also doesn't collect charcoal from the burnt trees near the volcano in ragnarok anymore. Great for fighting broodmother and doing artifact runs on the island and caves that are filled with insects. Definitely worth taming
