listen gold helm x2 + handcuffs + undead skull/high-tech dildo goes hard.
another one is bloody claw x3 + handcuffs.
litterally 4 of any one thing is fun if not OP.
oh and slow but easy combo is gold helm x3 + undead skull/high-tech dildo.
although I think undead skull is better than the high-tech dildo.
my begginer combo was orge essence + guerilla head x3 got very close to killing the boss with this at the begging.
x4 orge essence = 2 shot the big girls and 1-2 shotting green boys once they start shooting lazers
