One run.
A better reason to go.

Build a useful shortlist in three steps

1. Choose a slot you can improve, then compare the useful stats against your current equipment.
2. Filter to observed drops for stronger acquisition leads. If you investigate a Classic or unverified association, make that uncertainty clear to your group.
3. Keep a second objective: a quest, an encounter test or a comparison of recovery time. A run without the target item can still produce a useful result.

One drop is enough to support an association, but not a reliable probability. A required level of one can occur on a quest reward or test record. Treat both as reasons to read more before committing a session.
