I find it easier to starve them. by letting them wake up, feeding them a carcass to heal them (which works for some reason) and then continuing to knock it out four or five times they will retain the hunger drain from each time you knock out without feeding it. That way you don’t waste as many narcotics trying to keep it asleep, it takes about 30 narc arrows to the head to ko which saves significantly more narcotics imo. Plus you don’t have to worry about it waking up cus that’s the point anyway lol
