How are you making the most of gold during Power Hour?

Try a no-fill Destroy the Encampment mission and save the super encampment for a repeat loop. Clear the first two waves, then use a single-target weapon to kill only the mist monsters in the third wave. Leave the other husks alive and move away until they despawn, then return for another cycle. Stop after clearing three of the four super encampments so you don’t accidentally finish the mission. Keep defenders away from the farming spot.

Bring a crowd-clearing weapon for the earlier waves, but switch before the third. Area damage can kill husks you need to leave alive and end the mission. Pick up the gold between waves to avoid interrupting fights. One reported estimate was around 1,500 gold from drops plus roughly 500 from the mission reward in about 20 minutes, but treat that as a ballpark. If the timer is nearly out, finish the encampment for the completion reward.
