During a boss fight:(Ref. Difficulty Level is 0.2)
If your rexes are above 10k health and have 280% damage,they are able to crush every boss before they sacrifice.
I repeated the boss fight many times.Yuty and Daedon had 50% of chance to die,and not one rex died.No rifle or rockets,pure tames fight.
Stupid pigs can levitate. How do I know? Well I got ambushed by some that jumped off a cliff onto me, so I grabbed my pteranodon once I respawned and flew over. I couldn’t find them so I dismounted to get my stuff just as the same pigs jumped off the same cliff that they had previously flew off and couldn’t get back up. I got my tapejara and flew back to find them again on top of the unclimbable cliff. I got them that time.
