Making the farm faster
Drop chance is only half the equation — the other half is how many rolls you generate per hour. Resource boosters from the market double every pickup, and the drop-chance booster stacks with it multiplicatively; both apply to Isos. Warframes that force extra drop rolls compound this further: Nekros’ Desecrate re-rolls corpses, Hydroid’s Pilfering Swarm and Khora’s Pilfering Strangledome squeeze a second drop from captured enemies. A full squad built this way routinely multiplies an hour’s haul several times over the listed rates.
Kill density beats a marginally better drop chance: a 5% source you can kill two hundred times an hour out-yields a 50% source you meet twice. That is why endless missions — Survival, Defense, Excavation — against the right faction usually beat hunting a single high-percentage enemy from the table above, and why the sortable chances here are a starting point rather than a verdict.
What Isos is used for
Isos is an ingredient in 3 blueprints in Digital Extremes’ recipe data. The heaviest consumers below tell you how much to stockpile — farming past what you can spend is time you could put into relics instead.
| Crafted item | Isos needed |
|---|---|
| Basmu | ×450 |
| Sirius & Orion Systems | ×100 |
| Ambassador Barrel | ×5 |

About these numbers
These are Digital Extremes’ own published drop chances, re-parsed from the official drop tables every day. The percentage is the item-specific rate within that source’s reward table — it is not the chance that the enemy drops something at all, and the two are different numbers.
We deliberately do not multiply DE’s two published figures together into a single “real” drop rate. They measure different things and DE does not document how they compose, so a combined number would look more precise than it is.
If you are farming to sell rather than to build, check what platinum is actually worth first — for many resources, selling Prime parts is a faster route to the same goal.
