Prioritize synergy
Accessories add another layer to a build. The source wiki recommends keeping pieces whose bonuses reinforce your weapon, trait and skill tree choices rather than equipping an item only because it is new.
Recheck after upgrades
Review accessories whenever you make a major weapon, trait or skill change. The source discusses accessories that can support damage, health, currency gains or cooldown-related stats; choose according to the problem your current setup needs to solve.
Consider crafting costs
The source recommends reviewing recipes before spending materials so you know which drops to save. It does not provide a verified recipe or material list, so check the current in-game menu before crafting.
