Enhanced Excavation Sites: Remnants may increase the number of Path of Exile 2 Currency excavation points or the rewards from each site.

Monster Density and Rarity: Some Remnants boost monster packs, rarity, or add rare elite monsters to Expedition zones.

Explosion Chain Bonuses: Increased range or damage for explosives, allowing players to trigger bigger chain reactions during excavations.

Example: A league might introduce a Remnant that causes excavation explosions to spawn additional monsters, thus increasing loot drops but also raising difficulty.

B. Unique League Items and Currency
Leagues often bring league-specific items or currencies that can only be acquired through their unique mechanics or zones:

Artifacts: League-exclusive artifacts might drop more frequently in Expeditions or from Expedition bosses.

Crafting Materials: New crafting currencies might be tied to Expedition Logbooks or excavation chests, providing powerful customization options.

Boss-Specific Items: Expedition pinnacle bosses may drop league-unique gear, increasing demand and cheap POE 2 Exalted Orbs farming value.
