Probably the most underrated Dino in the game! They can actually harvest a massive amount of metal, crystal, stone, flint, and obsidian. In Ragnorok there is a ravine by the volcano in the highlands underwater, One run in this ravine will give u 10,000 metal ingots and well over 10,000 obsidian from the same dark gray rock.

A Dunkle Fish is really good for harvesting oil from the underwater nodes, along with a bit of stone. They also are useful fighters, with moderate melee and high health, though very low speed

Just lv up movement speed and this will be your oil friend forever

They can now gather metal, which is fantastic! They have decent weight also.

They van harvest a lot of oil with good stats, and they also drop a decent amount of chitin.
