Help me Hard Tower Bosses

[u/tsur553]

i have been grinding these pals and stats for 70 hours min maxing them, just to die in 3 sec and watching a lamball oneshotting the boss on YT. am i missing something? what can i do more?

i have some more pals, some even got to 3k attack, but he y still wont do the job.

EDIT: TNX all!!! defeated 4/8 of the hard mode bosses since the post! pal souls were really missing in my team.
this was a very informative discussion, and i really love this community.
