I found in a few battles in a row, my level 20 Bajatonodon will get knocked off by Mammotheriums Definite Power Rampage, I think even if a distraction is applied to it. It may survive if there were 2 distractions applied.
I think Baja gets picked on because it has higher hit points than the other 3 creatures I was using which were Tyrannolophosaur, Tryostronix and Allosinosaurus which is a great trio of damage dealers. I then ran with my usual Diloranosaurus and did fine. Mother picked on the next highest instead… Allosinosaurus who can seem to survive as Dilo and Tyranno can both distract in the previous turn.
If I used a higher hit point creature or something with taunt, I could make it past this rampage. I’ll play around and see what I can come up with another week maybe.
