Evidence methodology
How to Test Cosmic Mart Item Interactions
Use controlled observations before publishing a best-item claim, multiplier, stack rule, or synergy recommendation.
Record a baseline
Capture the mercenary, visible item description, room context, and result before adding another variable.
Change one variable at a time
Avoid changing mercenary, room pressure, and several items simultaneously.
- Record exact in-game names.
- Keep screenshots of descriptions.
- Repeat the interaction in more than one room.
Assign a confidence label
Use observed for one visible result, repeated for a reproduced result, and confirmed for an official statement or stable multi-run finding.
Avoid unsupported precision
Do not assign exact multipliers, drop rates, or tier positions when the evidence only shows that two effects appear together.
