U can use procoptodon to jump on the mushrooms on the island brood arena where it can't get u and u will be safe while the dinos u bring kill it on the ground. Also use comp bow as it does massive damage to it
For this fight, you will need to bring 19 high level megatheriums and one high level yutyrannus. You will also need good saddles and the BEST armour you can get from this fight. The entrance to the fight is the Green Obelisk Terminal, which is located at the co-ordinates, 589723. The megatheriums get an insane strength buff from killing insects. If you bring a yutyrannus to encourage them, their attack and defence will increase by 20% which is vital for fighting this boss.
The Artifact Of The Clever: 416466
Follow the path and turn left every time until you reach a water chamber, where the artifact is.
The Artifact Of The Hunter: 800535
Literally go to the left every time, jump off a little ledge and bam. You've found the artifact. (Simple as lol 😆)
The Artifact Of The Massive: 707862
There are a lot of dangerous jumps you have to make in this cave, so you are going to stick to the right, every single time, until it leads you to the artifact at the end of this cave.
You will also need 4 Tribute items:
1 Argentavis Talon
1 Sarcosuchus Skin
1 Sauropod Vertebrae
1 Titanoboa Venom
Set all dinos to passive, before entering the arena, and once you have entered the arena, immediately ride your yuty and set your dinos to attack your target. (Remember to use the courage roar from your yutyrannus, in order to buff your megatheriums!)
Once you have defeated a boss, you will unlock tekgrams for tek construction and you will unlock 25% of the tek armour.
And also, remember to store your alpha/beta trophy safely, because you will need that later, for the overseer boss.
You can bring megatheriams 2 yutys some daedons and I will reccomend some argos I picked these is because the argos can't AGGRO and do a huge amount of damage and with the yuty roar buff they can make them more stronger the megatheriams cause they get a big buff when they kill bugs and with the yuty they can be even stronger the daedons cause they can heal you and you can kill the gamma the beta and the alpha with these tips(please like this cause this is my first time posting a review)hope this was helpful
Stop saying to bring rexs, megatheriums are the optimal Dino for this fight. 17 megatheriums, 2 daedons, and a yuty should be able to take down Alpha Broodmother with low casualties. (With good stats of course)
