If you fish these with sap/leech blood, you can get alot of things. Fish, leech blood, metal, iron ingots, angler gel, hide, keratin, rare flowers and mushrooms, obsidian, prime meat and fish, silica perils, organic polymers, then plenty more! Fishing will be something you want to do. I recommend alot of rods premade, get a seprate base just for sap collection, andddd ofc a raft full of chairs.
