Gold making

Hmm i will try.!

Only Patroll The Depths will drop Maelstrom?

Maeltrom ES drops more in Contract Hero Mode and The Last Fragment Hero Mode. The more difficult the run, the more likely the scroll will drop.

Maelstorm never drops. It's a 1/20 chance you'll get it.

farm trees in twilight desert is fairly profitable if you are consistent

drops like spirit water and lambent powder worth a decent amount of gold

spend a couple of hours a day and you will have loaded with gold

it could get boring after awhile thuo

I would say from PtD for mael/sentinel ES.

From what I gathered, farming raids such as Keaghan, Dragons, Titan, Thor gives a good income. Also, PtD hero for ES scrolls like Force/Mael/Sentinel. Twilight Desert also gives good money.
