The best method is using megatheriums, they have a buff when they kill bugs and spiders and … that they do more damage and take less damage, 18 megatheriums (high melee and health , I recommend mutating and imprinting and leveling , watch syntac’s guide video for that) and you need a good yutyrannus with high Stam and health, and also a daeodon, put food in the daeodon because it’s healing ability needs food in it, put the daeodon on ignore group whistles with interacting with its behavior setting, ride the yuty in arena, use your courage roar ability to buff your dinos, every 10 second get off your yuty and use your daeodon ability for healing your megatheriums while they are fighting, I couldn’t explain better than this, for more help I recommend watching syntac boss fighting videos
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
In order to defeat the Broodmother u have to take in mind evey aspect of the fight, so I recommend always going for gamma first, just so you know what to expect, never underestimatw the Broodmother, its one of the bosses and way stronger than ANY wild dino. A yutirannus is very helpfull for buffing your team, if u can ALWAYS take a tribemate that is around your level, some dinos are way better when being ridden. I personally suggest a pack of high level deynonichuses (only on Valguero) with high health and stamina, because they can jump and cling on to the Broodmother to constantly do bleed damage at the cost of stamina, while also being able to bite it. All the dinos other people recommend are good, but make sure u have the basics : a bunch of high damage high health dinos, a creature with the ability to buff allies, and 1-2 healers, and some of your personal picks :) Good luck survivor !
So I’m going for my first ever run on the Brood I’m taking 10 Rex 2 Uty Rex 3 Deodons and 5 Megatheriums all over 200 lvl I should be ok I hope ! I think I have covered all the bases ! Rex Tanks and Dan UtyRex constant Agro Buff The Megas get the Insect buff and the Deos heal everyone ! Feel free to leave feedback I’m nervous lol
