Sausion
Sausion is an augment that is all about increasing your gold intake. This augment is a rank 2 Mage skill that increases your selling prices by 15%. The best part about the augment is that it stacks. So, if all four party members have the augment, you will get 74.9% more gold than you normally would while selling something.
You’ll be able to equip yourself and your main Pawn with the augment once you unlock it, but finding Pawns in the rift with the augment is a bit more challenging. But if you take your time and look through each one (preferably over level 35 which is when the augment unlocks) you will eventually strike gold. Favorite those Pawns so you can release them when done and find them again. But, while you have them with you, go sell all of your wares.
