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

Dont have smelting enabled when using the mortar attack it drains hunger completley and then you have to force feed him stone in order to shoot another one again

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.

Do not start smelting with a baby, juvenile or adolescent magnasaur because smelting drains there food and will slower die

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

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

IMPORTANT: Its not listed in the harvesting stats,but these babies are incredible crystal farmers too, they don't reduce weight but get a lot more than ankies or doeds.

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)

On the console version they are found in the Volcano Map of Genesis

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

If you see one and you took its egg just run and be where it shoots fire balls so be where

Magmasaurs cannot (ironically) collect Ambergris or élément. You need an Ankylosaur for that. They do collect tons of everything else.

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

You can equip the mining drill while riding most tames, magmasaur included. Drill does weight reduction on wood stone and metal so while out farming with your magmasaur you can keep the stone and ditch the doed.

Heads up! Takes a LOT of fall damage.

Can be bred on valguero, in the cave with artifact of the crag. ~35 ~51

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

I’ve learned that throwing a high level Rex to kill everything works really well

These things are really good at gathering crystal and obsidian.
