Warframe Mods Explained (2026): Capacity, Polarities, Every Kind of Mod, and Endo
Capacity, polarities, every kind of mod, and Endo
The short answer
Mods are the cards that turn a rank 30 frame or weapon into a build. Capacity comes from rank (30, or 60 with an Orokin Catalyst or Reactor), every mod has a drain, a matching polarity halves it, and Forma changes polarities. Rank mods with Endo, get the Galvanized and Primed versions when you can, and stop at eight slots plus Exilus, Aura or Stance.

MeleeCapacity and drain

| Capacity | Equals the item's rank, up to 30; an Orokin Catalyst (weapons) or Reactor (Warframes, companions) doubles it to 60 |
| Matching polarity | Mod drain halved, rounded up |
| Wrong polarity | Mod drain +25 percent |
| Aura and Stance | Add capacity equal to their drain; doubled when the polarity matches, reduced 20 percent when it does not |
| Forma | Adds or changes one slot polarity, resets the item to rank 0; Aura Forma, Stance Forma and Omni Forma make a slot take any polarity |
| Slots | Warframes: 8 plus Exilus and Aura. Primaries and secondaries: 8 plus Exilus. Melee: 8 plus Exilus and Stance. Companions: 10. Necramechs: 12 |

Ranking mods with Endo
- Each rank costs double the Endo of the one before. A common mod to rank 10 is about 7,700 Endo; a rare one about 23,000; a Legendary or Primed one about 30,700.
- Endo comes from Ayatan sculptures, Arbitrations, dissolving duplicate mods, Rathuum and Sorties.
- Rank up in the Mods screen or from the Arsenal; you can stop below max rank to fit capacity.
- Transmute four unwanted mods into one random mod when nothing else is left.
Where mods come from
- Enemies: almost every enemy has a small chance to drop a mod; bosses have their own tables.
- Nightwave: the Cred shop sells Auras and staples every rotation.
- Syndicates: augments and weapon mods for standing.
- Baro Ki'Teer: Primed mods every two weeks for Ducats.
- Arbitrations: Galvanized mods for Vitus Essence.
- Vaults: corrupted mods on Deimos, Requiem mods from relics.
- Trading: almost every mod trades; Rivens and Primed mods are the platinum market.
