In the Archnemesis league, you’ll build your own Rare boss fights by applying new monster modifiers to petrified monsters, found throughout every area. These modifiers add dangerous behaviours to their targets but also imbue them with valuable rewards. Each subsequent petrified monster you imbue within an area keeps all of the previous modifiers applied, allowing you to build some extremely difficult and rewarding encounters. There are over 60 new boss modifiers to discover, more than half of which can be created by combining other modifiers in specific recipes to unlock the most powerful and rewarding modifiers.
