Equipment and budget

The interactive armoury recommends a curated, boss-appropriate equipment progression within the bankroll you enter. It also shows worn slots, item statistics, live quoted values and the inventory cost separately. It is not a maximum-DPS simulator, and it cannot verify your levels, quests, charges or unlocked travel routes.
