When fighting this beast, I would recommend to bring herbivores( i recommend the tickle chickens) as the boss does extra damage to carnivores.

this is yet another situation where you bola your friend and run for your life

Use as many therizinos as you want since it does extra damage to carnivores technically since the therizino is an omnivore which means carnivore and herbivore put together so since the other half is herbivore it should block out that affect I would also recommend pumping damage and health. Thanks for using your time on my tip I hope it helps you beat the boss.

10 people 10 rexes maybe a yuty but look up and suround it will trap it.
