he can. the growing boss wont grow if ur on different heights, so what u need to do is wait for him to shrink going up and down ladders until reaches normal size (tiny) then u can damage. i find delegator is best 4 me.
ok it was just that the delegator is amazing but i can't hurt that boss nor can he hurt me when he is big so I'm just stuck on that level I will try your strategy thank you
