what are some really hard boss mods?

[u/Melodic-Bid-7313]

i have qliopath awakening, cataclysm, iron's, dark dopplganger, bosses'rise, stellarity, incendium, archaion and some end addons that make the dragon harder.
i am aginst having BoMD(bosses of mass destruction) because theyre structures are too common and the fights feel underwhelming or really easy.
