Case Study 5: “Echoes of Path of Exile 2 Currency the Past” League
League Overview:
“Echoes of the Past” league introduced an Expedition mechanic where excavation sites could occasionally trigger echoes—spectral duplicates of past bosses and elite monsters with altered abilities.

Impact on Expedition Farming:
Unpredictable Encounters: Echoes appeared randomly and could vastly increase the difficulty of Expeditions.

Reward Boosts: Defeating echoes yielded unique loot and boosted Logbook drop rates, making them highly desirable targets.

Risk Management: Players had to decide whether to engage echoes or bypass them to avoid potentially lethal fights.

Build Diversification: Versatile builds with strong defensive capabilities and cheap POE2 Currency AoE damage became favorable to handle unpredictable enemy types.
