I was really struggling to get an egg and now I have a family of magmas thanks to this. what I did was use a shadowmane to jump and stealth though the bugs and once your at the nest area jump as high as you can and try to land in the nest and then hit cloak as soon as you touch ground. Quickly grab the egg hop back on your shadowmane that should still be cloaked and then super jump out also leave your shadowmane on passive and no follow as if it follows you and steps in lava ur dead with it
