Cluster Grenade gives the Mercenary a punchy, hands-on way to play Path of Exile 2. You are not just holding down one attack and hoping the screen clears. You are picking spots, watching enemy movement, then dropping a burst exactly where it hurts.
Most players don't lose money on Breach because the mechanic is weak. They lose money because too much of the map is spent walking, sorting loot, or fighting packs after the encounter has stopped paying well. Hiveblood farming takes the opposite approach....
