Path of Exile
Players create and reset zone instances to repeatedly farm favorable layouts, bosses, or league mechanics faster than intended. It is a foundational PoE efficiency exploit.
Across different eras, stash, migration, and rollback issues have occasionally created duplicated items or currency. Even rare cases heavily affect the economy.
Some older mechanics let players keep powerful aura or buff states after changing gear or gems, preserving advantages that should have disappeared.
Traders can list bait prices, avoid sales, then relist higher once market trackers update, exploiting PoE's opaque and delayed trade economy.
Narrow doors, pillars, and terrain bottlenecks let players channel or cast from unusually safe positions while enemies path poorly. Many builds abuse these layout quirks.
