Not sure if it's a PC thing but eels and jellys can knock you off on Xbox and kill your little lite brite. However they are amazing at getting pearls in the little river on Ragnarok. Haven't tried going after the black pearls yet.
This is kind of horrific amd not the most humane thing, but here goes. You can get a few of these, breeds them, and kill the children for angler gel. Just saying 😶
