Build a base that survives the next wave.
Use role-based diagnostics and transparent roll math to improve your Build a Base RNG setup—without fake codes, invented stats, or copy-paste tier lists.

01 / BASE LAB
Diagnose the weak layer.
Tell the lab what your loadout contains. It suggests one controlled change, so you can see what actually improves the run.
Balanced test build
Strengthen the first layer that leaks, then repeat the same wave.
02 / ROLL MATH
Rare does not mean due.
Pick an observed object odds value and see the real chance of finding at least one across your planned rolls.
How the math works →Listed odds are community-observed and may change. This calculator assumes independent rolls and no luck modifiers.
About 1,040 rolls for a 50% mathematical chance—not a guarantee.
03 / FIELD NOTES
Guides built around the loop.
Short routes for the moments that change a run: the opening build, the first leak, and the boss checkpoint.

First 20 Waves
Build a stable loop before the first major boss checkpoint.
