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:
# Navigate to the Mods Console in the Orbiter. Alternatively, while using the Arsenal, click on 'Mods' at the bottom of the screen.
# Select the mod you wish to upgrade.
# Select the option Fusion.
# Adjust the desired mod rank.
# Select the option Apply fusion.
# A popup will appear with both credit & Endo cost.
# 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, Uncommon and Peculiar Mods, Rare and Amalgam Mods, Legendary Mods: 
:Requiem Mods: 
* Obtained Endo is rounded up.
Endo 	Rank	Rank	Rank	Rank	Rank	Rank	Rank 	Rank 	Rank 	Rank 	Rank
Endo 	0 	1 	2 	3 	4 	5 	6 	7 	8 	9 	10
Common 	5 	13 	28 	58 	118 	238 	478 	958 	1918 	3,838 	7,678
Uncommon 	10 	25 	55 	115 	235 	475 	955 	1,915 	3,835	7,675 	15,355
Rare 	15 	38 	83 	173 	353 	713 	1,433	2,872.5	5,753	11,513	23,033
Legendary	20 	50 	110 	230 	470 	950 	1,910	3,830 	7,670	15,350	30,710
===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 (EBC):
:Common Mods: 
:Uncommon and Peculiar Mods: 
:Rare, Amalgam, and Riven Mods: 
:Legendary Mods: 
The amount of Endo needed to rank up a mod is given as:
Endo to rank 	 	Rank	Rank	Rank	Rank	Rank 	Rank 	Rank 	Rank 	Rank 	Rank
Endo to rank 	 	1 	2 	3 	4 	5 	6 	7 	8 	9 	10
Common 	From Previous 	10 	20 	40 	80 	160 	320 	640 	1,280 	2,560 	5,120
Common 	From Rank 0 	10 	30 	70 	150 	310 	630 	1,270	2,550 	5,110 	10,230
Uncommon/Peculiar 	From Previous 	20 	40 	80 	160 	320 	640 	1,280	2,560 	5,120 	10,240
Uncommon/Peculiar 	From Rank 0 	20 	60 	140 	300 	620 	1,260	2,540	5,100 	10,220	20,460
Rare/Amalgam/Riven/ Galvanized	From Previous 	30 	60 	120 	240 	480 	960 	1,920	3,840 	7,680 	15,360
Rare/Amalgam/Riven/ Galvanized	From Rank 0 	30 	90 	210 	450 	930 	1,890	3,810	7,650 	15,330	30,690
Legendary 	From Previous 	40 	80 	160 	320 	640 	1,280	2,560	5,120 	10,240	20,480
Legendary 	From Rank 0 	40 	120 	280 	600 	1,240	2,520	5,080	10,200	20,440	40,920
===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 (CrBC):
:Common Mods: 
:Uncommon and Peculiar Mods: 
:Rare, Amalgam, and Riven Mods: 
:Legendary Mods: 
The amount of Credit needed to rank up a mod is given as:
Credits to rank 	 	Rank 	Rank 	Rank 	Rank 	Rank 	Rank 	Rank 	Rank 	Rank 	Rank
Credits to rank 	 	1 	2 	3 	4 	5 	6 	7 	8 	9 	10
Common 	From Previous 	483 	966 	1,932 	3,864 	7,728 	15,456 	30,912 	61,824 	123,648	247,296
Common 	From Rank 0 	483 	1,449	3,381 	7,245 	14,973	30,429 	61,341 	123,165	246,813	494,109
Uncommon/Peculiar 	From Previous 	966 	1,932	3,864 	7,728 	15,456	30,912 	61,824 	123,648	247,296	494,592
Uncommon/Peculiar 	From Rank 0 	966 	2,898	6,762 	14,490	29,946	60,858 	122,682	246,330	493,626	988,218
Rare/Amalgam/Riven	From Previous 	1,449	2,898	5,796 	11,592	23,184	46,368 	92,736 	185,472	370,944	741,888
Rare/Amalgam/Riven	From Rank 0 	1,449	4,347	10,143	21,735	44,919	91,287 	184,023	369,495	740,439	1,482,327
Legendary 	From Previous 	1,932	3,864	7,728 	15,456	30,912	61,824 	123,648	247,296	494,592	989,184
Legendary 	From Rank 0 	1,932	5,796	13,524	28,980	59,892	121,716	245,364	492,660	987,252	1,976,436
===Example===
To rank up a legendary mod from rank 0 to rank 10 would cost to fuse whereas the same operation would cost 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 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 Standing.
*Note that stat increases are not always linear with rank. One example is where Damage Reduction gets a 5% increase from Rank 0 to 1 but gets a 10% increase from Rank 2 to 3.
