These are the mechanics that will slightly interact with maps, but the majority of the mechanics themselves happen outside of maps, in their separate areas or arenas.

Sanctum

Sanctum is a roguelike mechanic in PoE that can be done separately from Maps themselves! We progress through the rooms and floors in search of treasure!

Synthesis

Synthesis is a mechanic that is mostly separate from Maps, where we can drop items that are Synthesized (implicit changed) or Fractured (golden-colored locked explicit modifier on an item) and it also has major content outside of Maps!

Heist

Heist as a mechanic is mostly out of maps, in maps there are Smuggler’s Caches which drop Heist contracts or Blueprints and Rogue Markers which are used as Heist Currency.
