Lich Minion Army Build - Last boss in the campaign & First map right after - Path of Exile 2 - 0.2

I leveled mainly as a minion focused build (SRS, Snipers, Arsonists, Unearth) and not as a EDC focused build (Essence drain & Contagion).
I played this in SSF Standard (First time playing SSF in standard so I did not have any extra items/gold from there).
I have now swapped to the Vaal Guard Spectres in maps since they are much stronger than Arsonists. You can start using them at the end of act 3.
FYI: The campaign in Act 2 is a struggle in the current state of the game.
