This would better streamline Dark sea farming aswell. When u do go to the dark sea u often have a luck potion for ur chests but getting the luck ingredient from the Dark sea itself would make it a reward for more exploration and going in deeper than u may be normaly confterable with. Getting good cataliysts and the regagent for luck potion definitly would make it more fun to go to the dark sea.
Tho i worry about fishing, yes sunken armor is obtionable there but i feel like by taking legendary scales away it lost something. But fishing itself prob needs a rework or just better rods and once jobs come maybe even perks. Maybe someday we will get the fishing rod that allows u ti fish up multiple fish at once.
