I think ark should make narcotic spike walls, because narcotic tripwire traps render it untameable. Narcotic spike walls will deal damage to the creature attacking them, but not as much as a regular spike wall. Then you could stand in a ring of narcotic spike walls with a pachyrhino, use aggro mist, and tame some of the unconsious creatures! To craft a narcotic spike wall, i think you should need: One spike wall and 5 narcotic. The narcotic spike wall is similar to the tranq arrow, ingreadients and function. Please ^ if you want this idea to come to life! ;D
While fishing, are you sick of all the fish being scattered? If you bring this dino near the shore or on a boat where fish are near by and use the aggro mist, it will aggro the fish to come right to you in a big crowd!
