Fusion

Fusion

Fusion is the process by which mods are upgraded to enhance their effectiveness. Upgraded mods increase in power via increments called ranks, with higher ranking mods having improved effectiveness than lower ranked mods, but at the cost of requiring more mod capacity to equip on Warframes and items.

Fusion is done via the Mods segment inside a player's Orbiter. In order to perform fusion, players must spend a resource called Endo, which can be acquired through missions.

Fusion Process

To perform fusion on a mod a player must do the following:

1. Navigate to the Mods Console in the Orbiter. Alternatively, while using the Arsenal, click on 'Mods' at the bottom of the screen.
2. Select the mod you wish to upgrade.
3. Select the option Fusion.
4. Adjust the desired mod rank.
5. Select the option Apply fusion.
6. A popup will appear with both credit & Endo cost.
7. Click Yes to continue.

Fusion Efficiency

A summary before the explanation:

• A mod requires a certain amount of Endo to rank up, which is dependent on the mod's rarity.
  • Uncommon mods require twice as much Endo to rank up as common mods, and rare mods need thrice the Endo of common mods.
  • However, an Uncommon mod will not give twice as much as a common, and neither will rare mods.

Endo value of mods

The Endo offered by one mod can be calculated with these formulas:

Common Mods: Endo Offered = (10 ÷ 3) × CurrentRank + 5

Uncommon and Peculiar Mods: Endo Offered = 7.5 × CurrentRank + 10

Rare and Amalgam Mods: Endo Offered = 12.5 × CurrentRank + 15

Legendary Mods: Endo Offered = 20 × CurrentRank + 20

Requiem Mods: Endo Offered = (500 ÷ 3) × NumberOfCharges + 500

• Rank is the number of blue stars.
• Obtained Endo is rounded up.

For example, the Endo of a Rank 6 Uncommon Mod is:

Endo Offered = (7.5 × 6) + 10
↪ Endo Offered = 45 + 10
↪ Endo Offered = 55

Endo	Rank
	0	1	2	3	4	5	6	7	8	9	10
Common	5	8	12	15	18	21	25	28	31	34	38
Uncommon	10	18	25	33	40	48	55	63	70	78	85
Rare	15	28	40	53	65	78	90	103	115	128	140
Legendary	20	40	60	80	100	120	140	160	180	200	220

Endo cost of mods

As stated before, the amount of Endo needed in the Fusion process is dependent on the Mod's rarity. This is due to different mod rarities having different Endo base costs (E_BC):

Common Mods: E_BC = 10

Uncommon and Peculiar Mods: E_BC = 20

Rare, Amalgam, and Riven Mods: E_BC = 30

Legendary Mods: E_BC = 40

The amount of Endo needed to rank up a mod is given as:

Fusion Cost from Current Rank = E_BC × (2^CurrentRank) × (2^{TargetRank - CurrentRank} - 1)
Fusion Cost from Previous Rank = E_BC × (2^CurrentRank)
Fusion Cost from Rank 0 = E_BC × (2^TargetRank - 1)

Credit cost of mods

To upgrade any existing mod with Endo you will also need credits. Credit cost, just like Endo cost, is based by mod rarity and its rank. This is due to different mod rarities having different Credit base costs (Cr_BC):

Common Mods: Cr_BC = 483‍483

Uncommon and Peculiar Mods: Cr_BC = 966‍966

Rare, Amalgam, and Riven Mods: Cr_BC = 1,449‍1,449

Legendary Mods: Cr_BC = 1,932‍1,932

The amount of Credit needed to rank up a mod is given as:

Fusion Cost from Current Rank = Cr_BC × (2^CurrentRank) × (2^{TargetRank - CurrentRank} - 1)
Fusion Cost from Previous Rank = Cr_BC × (2^CurrentRank)
Fusion Cost from Rank 0 = Cr_BC × (2^TargetRank - 1)

Credits to rank		Rank

	From Rank 0	1,449	4,347	10,143	21,735	44,919	91,287	184,023	369,495	740,439	1,482,327

Example

To rank up a legendary mod from rank 0 to rank 10 would cost 1,976,436‍1,976,436 to fuse whereas the same operation would cost 494,109‍494,109 for a common mod.

Notes

• Similar to fusion, but with a twist, mod Transmutation essentially fuses 4 mods together, along with varying credits, to create a randomized mod. This method of fusion is very expensive as opposed to normal fusion, with the cheapest fusion price at 12,000‍12,000 if not using Transmutation Cores
  • This high credit cost can be negated entirely by using a Transmutation Core, which can be acquired from Cephalon Simaris at his sanctuary for 5,000‍5,000 Standing.

Patch History

Update 12.2

• Cannot start a fusion with a card that's already at its max fusion level.
• Refined and tweaked new “Auto Fusion” features:
• Added some safety checks so that auto fuse never grabs installed mods or fused mods that aren't Fusion Cores.
• Now if you're fusing a ‘cooked’ mod, Auto Fuse WILL grab any raw duplicates of said mod.

Update 7.6

• Reduction of fusion costs and simplified conversion formulas (now linear scaled with proper rate of return on high-end cores).
