Just bring deinonychus that are imprinted and mutated in health damage and stam

Heres a tip FOR ALL THE PEOPLE SAYING YOU CAN FORCETAME IT IN THE ARENA- if u go into the bosses arena and forcetame it.... you'll be stuck there forever bc the boss gotta die in order for u to leave. :)

I joined a random server and found the arena and then a tribe with Rex’s and stuff summoned it I sneaked in behind them they lost but I managed to kill it by looting the dead bodys 😂

Bring around 6-7 or more rexs and when it lands everyone get around it and trap it. Deathworms will come and knock u back but just keep moving forward slowly so u dont get pushed out. Even when the rock golems come don't stop hitting it. Goodluck boys :)

When fighting the manticore a good strategy is bring in high level Rex's with good saddles and circle the manticore it then becomes pinned allowing you to kill it without it flying all around .... watch out for the poison it shoots at you though it will kill you off your mount like the poison wyvern ..

Just don’t run away otherwise you will get backstabbed because it is so fast

It's low on hps when golems come

If you have a Basilisk, USE IT. They are immune to sleeping and can’t be knocked out, I was able to solo the Alpha Manticore with a basilisks and a couple of guns
