About D2 Armor Lab
D2 Armor Lab is an unofficial Destiny 2 buildcrafting tool. It turns target stats into a short list of Armor 3.0 rolls to farm, without asking for a Bungie login.
Why this calculator exists
Inventory optimizers find combinations from armor you already own. D2 Armor Lab handles the step before that: deciding which archetype, tertiary stat, and tuning roll is missing. Each result contains five armor profiles to look for.
How the data is maintained
The model uses Bungie's Armor 3.0 rules and the Monument of Triumph armor update. It includes all 12 archetypes, Tier 5 30/25/20 rolls, masterwork bonuses, +5 and +10 stat mods, tuning, and subclass fragment offsets. The main page states the model date and assumptions.
What the tool does not do
The site does not connect to Bungie, inspect your inventory, choose armor set bonuses, or promise that a roll will drop. It does not replace an inventory optimizer. Use the tool comparison guide to decide which stage of the workflow you are in.
Independence
D2 Armor Lab is an independent community project. Bungie does not sponsor or endorse it. Destiny, Destiny 2, Bungie, and related marks belong to their respective owners.
