The idea with this tool is to provide a way for the Destiny 2 community to explore loadouts from high-skill players for challenging activities. Getting into buildcrafting can be daunting for new/returning players. We're hoping by providing a large, very filterable list of loadouts across all endgame activities, more people will be able to get into it.
From there, in typical light.gg fashion, we want you to be able to really drill down into the data and say things like "show me all Gunslinger Hunter loadouts using Classy Restoration and The Last Word" or "show me all Trials loadouts that include an Auto Rifle" and so on.
Eventually, as we gather more and more data, it will also be interesting to take a look at any trends that emerge and present those to the community as well.
The following are stored when the snapshot is taken: everything related to the activity that was completed, which character completed it, their full equipment loadout, and the power of each piece of equipment. Ancillary details like Triumph score, Artifact Power, Conqueror/Flawless Gilds, Clan Name, Emblem, etc. ARE NOT stored on our side and are summoned from the Bungie API whenever the page is loaded.
The amount of data storage necessary to make the loadout database happen is significant, so we're trying to only store what's absolutely essential in order to show what loadout someone was using. However, if it becomes a problem in the future, all of these things can be added to the snapshot if necessary.
Those letters are the weapon's Popularity Rank.
The popularity ranks displayed are there to allow you to compare that particular player's roll to the most popular roll for that weapon. That's all. It's not making any attempt to tell you whether their roll is good or bad — just popular or unpopular.
Part of the hope here is actually to show people that the game's hard activities can be done just fine with a wide variety of rolls, and that each player should focus on finding what works for them and they enjoy playing with.
At the same time it is also reassuring to be able to see how many S and A ranked weapons show up in these loadouts. Though it's not 100% bulletproof, things are often popular for a reason, and being able to have that reinforced when it should be (and discouraged when it shouldn't) is a good thing.
Most exotics and some legendary weapons have a fixed/"curated" list of perks set explicitly by Bungie. Those types of weapons all have the same roll, making it impossible to say person X's copy of Truth is any more popular than person Y's — they will both always have the same roll. Because of this, popularity ranks are only displayed on exotics and legendaries which are randomly rolled or crafted.
The number to the left of the icon is the total stat value of that piece. If an equipped mod further increases those stats, a second line with the value of that increase is added (such as +10)
The number in the top left of the icon indicates the energy type and level of the piece.
The number in the bottom left of the icon is its power.
The number in the top right and the bar to the right are indicators of how efficient the armor piece's roll is. See the Armor Analysis explanation below for more details. If the piece is a pinnacle/high stat reward, a star will appear underneath its roll efficiency.
Since Armor 2.0, armor pieces randomly generate their stats when dropped. This section attempts to implement the logic researched by community members JpDeathBlade and Testifye to measure how efficiently the stats of a piece of armor are rolled. (Click on either of the names above to read their full research yourself)
Roll Efficiency / Block Utilization are not an attempt to comment on how "good" a piece of armor is. Every guardian is looking for something different in each of their loadouts. You may value high Mobility while another person values high Recovery. This feature is not trying to comment one way or another. The only purpose is to try to say "assuming you like the stat DISTRIBUTION on this piece, here's how good your luck was with the values you got within that distribution".
With all that said, the gist of how armor rolls goes something like this: (Pinnacle/High Stat/Exotics have a slightly different process that's explained further below)
The Roll Breakdown section attempts to visualize the best case scenario of how an armor piece's roll could be reached. Each stat lists how each point is granted by a variety of color-coded marks. You can hover over/tap any point to see which component of the roll's value it is contributing to:
Block Utilization is the percentage of the total stat points within the blocks required to represent the roll that were not missed. Higher means the roll is more efficient / closer to the best possible roll within that stat distribution.
Exotic Armor seems to roll the same as normal, except it allocates 5 blocks to each stat group instead of 4. For this reason, exotics will tend to have higher stat rolls than legendaries.
Pinnacle/High Stat armor can roll with up to one additional block per stat group (Mobility/Resilience/Recovery | Discipline/Intellect/Strength). Whenever the Roll Breakdown determines more blocks than the standard 8/10 are required to represent the stats on a particular armor piece, the Pinnacle/High Stat indicator will appear.
There's also some hairiness around certain armor pieces having a predilection for certain stat distributions. This tool doesn't attempt to address that. Check out D2ArmorPicker's Mijago's Twitter for ongoing research on that topic.
That's entirely possible. The tool, as stated above, attempts to calculate the best case scenario. A piece will only be marked pinnacle/high stat if the number of blocks required to represent it exceed the default of 8 (10 for exotics).
Part of the reason we show the Pinnacle/High Stat indicator is to draw attention to the fact that having access to more stat blocks makes it more difficult to use them all efficiently. More blocks = more stat rolls = more chances to "miss". For this reason, the block utilization stat should not be used alone to measure an armor piece's quality. It is entirely possible for an armor piece with higher overall stats to have a lower block utilization simply because it is Pinnacle when another piece is not.
Hovering over the hint circle next to any of their labels will provide an explanation of what they mean. In general, Popularity stats on light.gg are determined by scraping the weapons used by the global Destiny 2 population.
The Popularity Rank is derived from statistics based on what the global Destiny 2 population is using over the past 2 weeks.
Theorycrafter Opinions are curated by trusted members of the community and are just that, their opinions. Those opinions can obviously disagree with what's popular. A weapon is marked "God Roll" if there's a theorycrafter out there that likes the perks in every column for both PVE and PVP.
Click the Share link at the top of the page. From there, you have a few different options. The Loadout Infographic is a PNG representation of the core components of the loadout with two QR codes embedded — one to bring up the loadout detail page you're currently on and another to export the loadout to DIM.
Alternatively, you can link directly to the loadout inspector by copying the URL from the address bar or clicking Copy next to the Direct Link option in the Share dialog.
