on the center when you get a low lvl quetz skip the trap and use platform quetz to hit high level with tranq arrows until he flies into cliff. park your quetz quickly behind it and switch to darts not missing a beat since stoping will allow quetz to turn and escape. every time ive done this the tame usually falls in safe high area
The fun way is to jump off and grapple to your argie and whistle it to attack and since argies are slow it won’t catch up in time so tranq till it goes out also bring parachutes and consider liking so more people will know
If you drop a quetzal due to knockout, and it lands next to a giga...just know, the quetzal belong to the giga. Now you get to watch your would be quetzal get eaten by a giga. Now you can go home and cry.
