I was taming a lv. 30 eerie, (I was on easy) and came unprepared. Narcoberries do not work. You will have to feed narc, then mejo, then narc and so on. Moral, do not forget biotic, from this I wasted 14 amber! And it is a female(yay) I have like no females but like millions of eggs
3 ways to tame them:
1. Make a stone trap (foundstion, doorframe, ramp, etc.). Get a bird, fly the bird, drag a dodo or a person around and make them bait. Without killing anyone the terror bird will be chasing you while you're flying in the air. Lure it into trap.
2. If you don't have a bird, you can solo it or do it with a friend. Find a terror bird. Start running to the trap. (Probably will die so put a bed in trap and respawn then repeat till bird gets trapped).
3. Bola it, shoot fast, bola it again before it tries attacking you or running away, shoot at it again.
TAKES AWHILE FOR THEM TO GO UNCONCIOUS. I once made the mistake and kept shooting as it took about 20 minutes for it to go unconcious it died from me shooting it too much.
YOU WILL NEED LOTS NARCOTICS!!!!
Taming a terror bird won't be easy because they come in packs of 3. So if you want one of them just kill the other 2 and tame the one you want. Mainly to tame one you'll need bolas, tranq arrows or a club to knock it out. Its preferred kibble or raw meat works faster and mutton.
Tip When they are hunting a animal like cornered on a rock stand at least 10 to 15 feet away with a crossbow at least 30 tranq arrows to be safe next start s hooting them from at least 11 feet while they are hunting a animal and killing it with a tranq arrow try aiming for the head if they are in packs try to be safe doing it
