You have to steal the egg and raise it yourself. You cant knock one out and tame it.

If anyone are on fjorder use the andrewsarchus with a saddle and 10.000 health and when you get there pump in damage now and there you go a fierce egg ready to grow for you

Looking like an nise gentile man

If you can’t feed it then you can use the snow owl to heal it or you can use an admin command (giveinfinitestatstotarget)

You can’t tranq these guys, they are like dragons you have to steal eggs. You can find their caves in the volcano area on Lost Island. Once you have some eggs you need to feed it Amber Gris as there is a glitch at the moment that won’t allow it to eat sulfur. You can only get the Amber Gris on Genesis so you will have to admin spawn it in if your playing unofficial. To get them to breed you need to breed them in lava

Go in with a deinonychus and be quick

The babies don't eat meat! They eat a strange stone or sulfur.

Tip: Magmasaur baby’s eat ambergris

Best mount to get the eggs is the bloodstalker you swoop in and grab it and swing out (the bloodstalker needs a lot of health)

When gathering eggs in the cave wear hazard gear to protect you from fire damage/attacks.

Found out you can ride gasbags on genesis and they work pretty well for quickly getting in and out with an egg, plus they can tank a lot of damage if you get hit by the fireballs

Magmasaur egg stealing: On Fjordur, head to the volcano with an Andrewsarchus. Beware Fire Wyverns and X Rock Elementals. Search for some magmasaur nests and grab the egg. Then run as fast as you can. There is some sulfur you can feed the baby magmasaur so it doesnt die. It smells metal and cooks raw meat. I don't know how to hatch it other then an incubator.

Hope this helps, Best luck to those who try.

a Magmasaur can defeat, hundreds of dinos quickly they are so strong they have crazy abilities it was really hard for me to get a Magmasaur

If trying to get one on the switch version they instantly respawn literally as you kill them. Here is a tip on how to get the eggs on switch: take a gasbag or whatever you use to get in the volcano (I prefer gasbag) and bring a velo or really any passive tame. With the magmasuars attention land on a safe cliff and toss out your passive tame within agro of the magmas: leave the passive tame, fly off out of render and come from the back side and grab your egg. They will chase you etc but leave render and repeat. Recommended to use a passive dodo in case the volcano erupts before you can grab it.

You probably won’t get outside of the cave you might get yo egg from unless yo got a high level bloodstalker and use at least 26 ACs to incubate the egg

To tame one of this things on fjordur. All you need is 2people with 2raptors that are not important, run inside the wyvern cave (good stam&speed) try rub through everything go in jump to the left and grabb a egg then use the teleportation to teleport anywhere safe, (we just did it and came our with 1raptor dead, 145egg

For some reason this works. Just hang from above a nest and then drop it there aren’t any ON the nest. Then grab and then quickly escape ( do all these on a bloodstalker ) in the time it takes for them to first Agro animation, then there ai says don’t swipe just charge a ball. It’s surprising how much time you have to grab a egg and get away is much larger than you think. Want proof, watch AxeMan’s idea when he gets his. He uses this strategy

Bring a good Assault Rifle or Fabricated Sniper when going into the cave. Kill all the nearby magmas on the nest you’re targeting. Go down, get the eggs, get out. Easy 2 eggs every time. (This is on official server)

I summoned a male and female using the command gmsummon “cherfue_character_bp_c” 55 100 false I made them sit in the lava at the center map and it worked to breed them

Easiest way to get eggs is with skiff grabbing a tribe member with a whip. Hover over egg and whip
