We all know how hard the boss in wave 50 is but I can tell you how to kill the boss follow instructions below.
We all know the boss eats our allies so here is how to kill him
1)upgrade leadership level
2)spam farmers at boss
3)(this is only if you have frostie the Bowman spawn 1 frostie
4)let all farmers attack the boss at once
5)be sure no extra enemies come to interrupt
6)join in the fight
7)(you can choose not to do it) bring out a swordsmith to boost your farmers
Then wait for some time and then the boss is killed
