A few tips I’ve learned to help you:

1) There’s an hour given between tame feedings. Don’t feel rushed to carry everything at once.

2) Eggs can land on top of trees, clear out the landing zone before building.

3) Like OSDs, wild creatures cannot destroy structures on PVE, you can take your time.

4) Neophytes can spawn far from the egg and get stuck, fly around a bit until the defense POI marker pops up.

5) Alongside 4, waves may still progress if a neophyte is stuck, a great luxury that OSDs don’t have. Track the egg with tek binos to be sure.

6) Higher rarity items (ones higher than what is requested) don’t seem to effect the taming progress very much, if at all. Save the high end stuff for high level ones unless you have no choice.

7) Neophytes take insanely huge damage reduction from tames. A high melee character and good weapon will make quick work of them. A gloon is unaffected by this reduction, bring one for some help.

8) If the Aureliax doesn’t “want to be feed right now”, you most likely have a shoulder pet, have the gloon on standby until the defense.

9) Two people on the last feeding helps a lot, one to feed and the other to call out when to feed. The egg drops wherever the head is at, have the other flying close to call out when and where to feed it. PVE structures or bad terrain can prevent building around the egg to defend it.

10) They seem to have set spawn areas and respawn quickly (could be bugged). Use this to farm the ones you want.

11) Egg gender doesn’t seem tied to the parents gender (could be bugged).

12) The cloning cost of a level 47 Aureliax is ~4950 shards.
