If you are on Ragnarok head to the highlands and along the coast and you will find beached basilosaurus. Harvest them with a pick or hatchet to get hide, keratin, oil and LOTS of spoiled meat. Killing vultures in the desert also gives you a lot of spoiled meat.
Use split all on a stack of meat that is about to spoil, then put meat that has a long time left to spoil into your inventory. The new meat will take on the spoil timer of the almost spoiled meat. Split all again, and repeat the process as long as you like, then use a tamed herbivore to get lots of narcoberries. 2,100 is a good number. Find a quadruple xp explorer note, divide your resources by the amount of mortar and pestles you have, which should be as many as possible, and you’ll level up faster than your parents can say “get a job”
