My experience was different for a level 45 then what this states. It took about the time suggested but like 30 less mejo berries and 100 less narcos and an 80% tame and 18 level gain compared to the said 65% 14 level gain..so..maybe it's been nerfed
If taming, watch the torpor rate EVERY SECOND and use Bio Toxin. Torpor drain rate RIVALS even the Therizinos’. Pro taming tip. Only use bio toxin when taming. Tame stuff with narcs ONLY when you have a narcoberry farm, and a crap ton of meat on your carnivorous tames. I only use narcotics for crafting tranq darts and tranq arrows. There are a crap ton of Cnidaria on South Zone 3.
