On this page of the Guide to Darksiders 3, we have included information on how to unlock new armor. It has better parameters than the default Fury armor, which makes it easier to win battles with stronger opponents.
Fury uses the Base Armor from the beginning of the game. You can check it in the inventory. Unfortunately, it does not have additional properties.
New armor must be purchased, and this option is not available from the beginning of the game. New armor becomes available for purchase thanks to unlocking the next essences (powers).
After receiving each new essence, visit the Vulgrim merchant. He will be selling armors associated with the given essence. I should add that, unfortunately, every next armor in Vulgrim's offer is more expensive, and it may take even several tens of thousands of souls.
After purchasing the armor you need to put it on. Open the inventory again and select it from the list.
Each best armor has a list of bonuses to statistics. It is worth studying these before deciding on the purchase and before choosing a new armor from the list.
