You may have noticed that unlike any other steal and hatch tame, magmasaurs can deal damage to you while you ride your mount, SO THIS IS HOW ITS DONE!! You get a ferox lvl 20 (higher if u can but dont name it... you'll see), then you lvl him in health, 500 in small form is ok, after that you have 2 ways:
1)KAMIKAZE(bloodstalker needed or some skill woth grappling hook); you transform your ferox and whistle him to riot right into the nest, the point of this is that all magmas use their magma bombs against him, so you can pick up your eggs and get out of there (its called kamikaze, dont make me write it)
2) I'LL TAKE YOU ALL ON; transform him, whistle attack, riot 1vs4-5-6, and then you charge with your highest dps dinos, lava doesnt do as much damage as on other maps, plus you can stay at the edge of the lava and you'd be fine, i used 2 rexes mated boosted w 7k health and 500 mele and i got out with everything alive and 6 magma eggs, you can use allo packs or spinos too. Extra tips? for
I’ve found the eggs. The eggs are located inside the volcano in an amethyst cave. There are lava pools with groups of magmasaurs in them. There are small islands with craters in them, within those craters the eggs are nestled within. But be careful there are lots of magmasaurs, magma, and what look like varient rock elementals.
Now that we can transfer in and out of the genesis servers I’ve been getting a bunch of eggs, and from experience the best tame to get eggs ISNT the bloodstalker is a rock drake. I know there kind of hard to get but there invisibility is the best we to get into the best and the wall climbing and gliding is the best way to get out of the volcano without and trouble
Easiest thing to do is to spawn at the East zone and go to the Egg-Straction mission. Then, take the first left in the cave and you should end up by the nest. A good strategy is to wait until there aren’t any magmasaurs by an egg, then ask HLNA to teleport away, and right before you teleport, grab the egg.
