Plan your Warframe relic farming with transparent math. We model the official drop tables for all refinement tiers (Intact, Exceptional, Flawless, Radiant), and compute best-of-squad probabilities so four Tenno can coordinate refinements and pick the highest-value reward every run. You'll also find expected value (EV) per run, EV per relic, confidence for "at least one copy" after N runs, plus a practical checklist on when to stop refining or switch targets. Every tool is documented with assumptions, formulas, worked examples, edge cases, and common mistakes—so you can verify the numbers and adapt them to your group's budget and time constraints.
Compute per-run success with best-of-squad selection, rare/uncommon/common buckets, EV from rare-only and full-table EV. Includes Radiant/Flawless/ Exceptional/Intact tiers, custom prices, squad size, and confidence by runs.

Each refinement tier shifts the probability distribution across rare, uncommon, and common rewards. Radiant relics maximize your chance at rare drops, while Intact relics offer the most economical option for farming common and uncommon items. Our calculator models all four tiers with official drop rates, helping you decide when it's worth spending Void Traces to refine versus running more missions with unrefined relics.
The best-of-squad mechanic multiplies your odds significantly - when four players each open a relic, you get to choose from four reward pools, dramatically increasing the probability of seeing at least one rare drop in the group.
