Transmutation is the method of combining unwanted mods and paying credits for a chance to create a more desirable mod. Many PvE mods are obtainable through this method. Certain mod classes, such as Corrupted Mods and Event-exclusive mods, cannot be acquired via transmutation.
There is no specific mod combination that produces a certain mod and is purely based on rarity and chance, though polarity and item compatibility are also factors. For example, fusing four 
Madurai mods has a higher chance of producing a random Madurai mod. Similarly, fusing 4 rifle mods will have a higher chance of producing a random rifle mod.[citation needed]
There is also no penalty for fusing the same mod, making the chances of getting a rare mod the same regardless of whether one transmutes four different or identical rares.
Use[]
Begin by selecting any combination of four unranked mods that you wish to Transmute. You cannot use mods you currently have equipped, Legendary mods, or Set Mods. After an acceptable combination is selected, the Transmute area in the middle of the mod screen will light up, telling you that you are ready to transmute your selected mods. Simply click the illuminated area and then confirm your selection. The cost of Transmutation varies depending on the rarity of mods used. Prices range from 
0 to 84,000, with the exception of Riven Mods:
- 0 for transmuting any three mods with a transmutation core.
- 12,000 for transmuting any four common mods.
- 24,000 for transmuting any four uncommon mods.
- 36,000 for transmuting any four rare mods.
- 24,000 for transmuting any four requiem mods, plus 3,000 for each remaining charge for up to 60,000.
- 24,000 for transmuting any four Archon mods.
- 72,000 for transmuting any four peculiar mods.
- 84,000 for transmuting any four amalgam mods.
- One Riven Transmuter for transmuting any four Riven mods.
You can mix mods of different rarities to get prices in-between. The end result of the transmutation depends on the collective rarity of mods used. Transmuting four common mods have a chance to produce rarer mods, but less so when compared to transmutations using mods of higher value.[citation needed] For example: combining four different rare mods is costly but yields a greater chance of producing a rare mod from the transmutation. Apart from that, the algorithm of transmutation is completely random — there are no recipes for even the simplest mods.

| Combination | Chance at Common | Chance at Uncommon | Chance at Rare | Chance at Requiem | Chance at Peculiar | Chance at Amalgam | Chance at Riven |
|---|---|---|---|---|---|---|---|
| 4 Commons | 95% | 4% | 1% | 0% | 0% | 0% | 0% |
| 4 Uncommons/ Peculiars |
15% | 80% | 5% | 0% | 0% | 0% | 0% |
| 4 Rares/ Amalgams |
40% | 10% | 50% | 0% | 0% | 0% | 0% |
| 4 Requiems | 0% | 0% | 0% | 100% | 0% | 0% | 0% |
| 4 Rivens | 0% | 0% | 0% | 0% | 0% | 0% | 100% |
Transmutation Cores[]
Transmutation Cores are special Cores that can be used as an ingredient in Transmutation. When used alongside three other Mods to be transmuted, the Transmutation Core ensures that the resulting Mod will be of matching Polarity listed on the Transmutation Core. Using a Transmutation Core also removes the credit cost for that transmutation, allowing for cheaper attempts at transmuting Rare-quality Mods. Transmutation Cores do not guarantee the rarity of the resulting mod, only their polarity.
Transmutation cores can be acquired from Cephalon Simaris in the relay for 
5,000.

Riven Mods[]
- Main article: Riven Mods#Transmutation
Riven Mods can also be transmuted. However, they require the use of Riven Transmuter, a drop from Eidolon Hydrolyst or purchasable from Loid for 180 
Vessel Capillaries, in order to transmute four unveiled, veiled, or a mix of them to produce one veiled Riven Mod. The resulting Riven Mod will always be of the same type as one of the transmuted Riven Mods. Because of this, if you use four Riven Mods of the same type, you will be guaranteed a veiled Riven Mod of that type.
Untransmutable Mods[]
- Main article: Category:Untransmutable Mods
Mods in the following categories cannot be acquired via transmutation:
- Flawed, Primed and Amalgam mods,

Certain other mods are untransmutable under no discernable criterion.
