Some tips from your God:
>Make sure all of your dolls stand in the aoe attack Flareberus does as for each doll hit he takes extra stability damage
>Have your 3 turn Tororo run and activate the stability enhancer at the top of the map
>When adds spawn they will try to turn them off, kill them
>When the boss enrages keep all of your dolls away from it except the one you're using to tank it
Good luck anon I'm sure you can do it with Springfield + Tororo. Grab Planeta for her if you can and it should be possible.
