Flashback

However, since most post-3.0 league unique items are tied to the mechanics (e.g. Abyss/Breach/Warbands monster/bosses, Legion/Blight encounter, tied to Beachhead Maps, tied to Perandus chest, etc.) instead of rely on league flag, those unique can still be obtained from Flashback league. Moreover, Zana use the same crafted modifiers that available to all 3.12 leagues, which Zana crafted modifiers can add league flag to the map area. Zana crafted map mod has a hidden property map_set_league_category which is not found in the relevant flashback mod.
