This is the case where my 2nd account with 94 level 20 & 21 creatures is better than my primary account as I more easily beat the trials than those level 30 strike towers.
I used my 2nd account 21 Grypolyth to easily defeat the trial but my primary’s best was a 21 Gryposuchus which lost… (level 21 because of an accidental evolve ). They really need an “Are you sure” or “Commit” button or 30 second chance to undo.
So the closest I had was a level 17 Gigaspikasaur which I leveled to 20 and was able to just barely beat the trial on my primary account.
My first sense it that trial towers will push players into leveling other things up and spend coins is still my thinking as I did this to beat one.
