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.
-Tip- A good way to get a lot of narcotics is taming a herbivore of your choice that gathers a good amount of berries, then heading to areas where turkey vultures spawn. kill the vultures for a large amount of spoiled meat and boom a good way of getting narcotics if you don’t like waiting for meat to spoil
Tame a bronto cause they’re easy, and use in forests to become the richest man with narcotics in the whole map, one swing and it gives you 2-3 stacks of narco berries!!! Then get a rex for obtaining meat to spoil.
Even if u have tranq darts these are still helpful because these can be used for taming when u knock something out and there about to wake up (when the purple bar is low) shove these in their inventory and then their torpor will increase (the purple bar goes up)
Don’t like waiting for meat to spoil? Go to areas where turkey vultures spawn and kill them for a good amount of spoiled meat ( if they spawn in on the map that you’re playing) or get a bunch of prime meat and put it in a box or player inventory and wait a few minutes
This is a great drug when first taming but when you have other options, use them. Bio Toxin ( dropped by Jellyfish ) is about two times as powerful but it spoils, so make sure to have these on your hands!
