This is the honest version of how the boss, drop, and weapon data on BL4 Tools is put together. We are an unofficial fan site, and we would rather tell you exactly where a number comes from than dress up a guess as a fact.
Where our data comes from
Every boss and weapon entry is built from, in priority order:
- Official 2K / Gearbox sources — patch notes, raid boss reveals, and the official Borderlands site. This is the top authority for new content like raid bosses and their loot tables.
- Established community boss guides — MentalMars, Fextralife, and game8, which document boss locations, mechanics, and dedicated drops.
- Community reports — Reddit and player video, used to cross-check the above, never as a sole source.
Each boss and weapon entry carries a source link and a verifiedFor patch stamp so you can see where it came from and how current it is.
What we deliberately do not do
We do not publish fixed card stats — damage, fire rate, magazine — for weapons. In Borderlands those numbers scale with your level and the individual roll, so a single “142,883 damage” figure is meaningless out of context. Where the in-game card matters, we tell you to read it on your own drop.
We do not invent drop percentages or fake sample sizes. When an official source or guide publishes a rate (for example, a raid boss at “15% +2% per UVH Rank”, or a world boss at “9% +2% per UVH Rank”), we cite that figure. When no reliable rate exists, the page says the item is a dedicated drop and stops there — we will not write a precise drop percentage with a confident-looking sample size unless that figure is real and sourced.
We do not claim an element for a drop we can’t confirm. Many drops can roll with different elements (or none), so where we are unsure the page marks the element unverified and tells you to check your copy.
When something is out of date
Game data changes between patches. If you spot a deviation in a current patch — a moved drop, a changed mechanic, a wrong location — email [email protected] and we will fix it and re-stamp the page. The patch stamp at the top of every entry tells you the last version we checked it against.
That’s the whole method: cite the source, stamp the patch, and never fill a gap with a confident-sounding number we made up.
