Missing details on being able to choose bonus during Valence Fusion

This weapon can be fused with another weapon of the same type into one with superior stats.

See: Actions > Valence Fusion
—In-Game Description

Valence Fusion is the merging of two similar Kuva Lich Weapons, Tenet Weapons, or Railjack Components and Armaments into one with superior stats.

Kuva Lich/Tenet Weapons[]

Valence Fusion combines two of the same Kuva or Tenet weapons into one with a higher Elemental Bonus, multiplying the highest bonus of the two weapons by 1.1, capping at 60% bonus. Valence Fusion can be found under the Actions button while modding a weapon. After selecting Valence Fusion, a player is required to choose another of the same Kuva/Tenet weapon from the inventory (not in Foundry or with the Kuva Lich / Sister of Parvos) to fuse it with. If the weapon's element bonuses differs, the player will be prompted to choose between the two available elements.

The final value of the Elemental Bonus after a Valence Fusion is performed is given by the formula:

Any other properties (Orokin Catalyst, Forma, Stance Forma, Exilus Weapon Adapter, or Focus Lens) do not transfer over, meaning the order of fusion is important. Put simply, it is best to equip the weapon with the most resource investment (weapon rank, Catalyst, Forma, and Exilus that you wanted to keep) and fuse other weapons to it.

After selecting the donor weapon to be used in the fusion, a confirmation screen displays the desired weapon's new damage type and bonus values and warns that the transfer will consume the selected donor weapon. Players are then prompted to type FUSE to confirm the fusion.

  • Example: KuvaKohm Kuva Kohm (A) has 40% DmgFireSmall64 Heat Damage and an Orokin Catalyst. Kuva Kohm (B) has 52% DmgRadiationSmall64 Radiation damage. The player has two options, to fuse (A) with (B) or to fuse (B) with (A).
    • Since 52% is higher than 40%, the result will always be according to the percentage of (B) and multiplied by 1.1, resulting in 57.2%.
    • Fusing (B) to (A): Equip (A), under Valence Fusion, select (B). The result of this will be a Kuva Kohm with 57.2% DmgFireSmall64 Heat or DmgRadiationSmall64 Radiation damage with an Orokin Catalyst. (B) will be destroyed.
    • Fusing (A) to (B): Equip (B), under Valence Fusion, select (A). The result of this will be a Kuva Kohm with 57.2% DmgFireSmall64 Heat or DmgRadiationSmall64 Radiation damage without an Orokin Catalyst. (A) will be destroyed.

Railjack Wreckage[]

Valence Fusion combines two of the same Railjack Components and Armaments (in respect to the House and Type) into one with superior bonus stats. This applies to Turrets, Shield Arrays, Engines, Platings, and Reactors, but does not apply to Ordnance or other Sigma Items. This can be managed in the Dry Dock. Stat increases are capped between 40% and 60% for weapons and miscellaneous values for components.

To perform Valence Fusion, players must click on the component or armament desired to be upgraded, and then the part to be used as the donor. Only the object to be upgraded must be constructed, while the donor item can either be repaired or unrepaired. If the component has a different MKIII unique trait, the player is prompted to select one.

If the player does not have enough resources, a failure message will notify the player which resources they are missing. If the item to be upgraded is already maximized, a failure message will notify the player that the item can no longer be enhanced further.

Once the components/armaments with stats below maximum have been selected and the player has enough resources, a confirmation screen displays the desired component's new bonus values and warns that the transfer will consume the selected donor component along with the required resources. Players are then prompted to type FUSE to confirm the fusion.

Costs[]

Fusing with repaired parts will require some Endo:

  • MK I: 800 Endo
  • MK II: 1600 Endo
  • MK III: 2400 Endo

Fusing with unrepaired parts instead of Endo costs 40% of the resources and Credits64 Credits that would be used to repair it (Any decimals are rounded up to the nearest whole number. Ex: 3.2 = 4).

Upgrading[]

Upgrades count towards the stat bonus on MKIII turrets and the random stats on other Railjack gear.

  • Fusing gear that is the same tier level (e.g. MKIII with MKIII) will yield an increase of stats by 10%.
    • Example: Fusing together Vidar Photor MKIII with +40% bonus damage with another Vidar Photor MK III with +35% bonus damage, results in one Vidar Photor MKIII with +44% bonus damage.
  • Fusing gear that has a lower tier level (e.g. MKII with MKIII or MKII with MKI) will yield an increase of stats by 5%.
  • Fusing gear that has a lower tier level by two (i.e. MKI with MKIII) will yield an increase of stats by 2%.
  • Fusing gear that has a higher tier level (e.g. MKIII with MKII) is equivalent to the same fusion the other way around (Results in MKIII Gear).

Extra Math[]

For Weapons and same-tier Armaments, maximum % bonus (60%) can be achieved in the following number of fusions:

Minimum Initial Value Maximum Number of Fusions
58.0% 0 (automatically rounded up to 60.0%)
52.8% 1
48.0% 2
43.6% 3
39.7% 4
36.1% 5
32.8% 6
29.8% 7
27.1% 8
25.0% 9

For example, a TenetEnvoy Tenet Envoy with a 42% Toxin bonus will need at most 4 Fusions to reach the maximum element bonus of 60%.

Trivia[]

  • Prior to Update 27.1 (2020-02-04), the system was originally titled Valence Transfer which would simply replace a Kuva weapon's elemental type and bonus.

Patch History[]

Update 36.0 (2024-06-18)

  • Fixed Valence Bonus stat sometimes rounding up decimals when viewed in the Arsenal or when purchasing from Ergo Glast.
  • Kuva and Tenet weapons with 58% Elemental Bonus or above will now automatically round that value up to 60%.
    • Players who have existing Tenet and Kuva weapons (including those pending in the Foundry) with 58%+ Valence Bonus will have this value rounded up to 60% upon logging in after downloading the update.

Update 30.7 (2021-09-08)

  • Fixed issue where fusing two partially ranked Kuva or Tenet weapons together appeared to increase the rank of your weapon.
    • This was a UI / display only, as the Valence fusion does not increase a weapon rank. Now, the weapon rank does not increase from fusion and the UI does not incorrectly show that it has.
  • Fixed a crash when attempting to Valence Fusion a Talyn Armament.

Update 30.5 (2021-07-06)

Kuva Lich (And Sister of Parvos) Valence Fusion QOL

We have made Valence Fusion for Weapons more intuitive in this Update! We are inheriting the behaviour we added for Railjack which was much more clear to our players!

  • Prior to this Update, when you used Valence Fusion to combine two Kuva Lich weapons together in the Arsenal, the order of the weapons picked would determine which element the final bonus damage would be.
  • In this update, when you combine two Kuva Lich weapons (or Sister Tenet weapons) together, you will have the option of which element you want to keep. The numerical stat of the element still combines using the same logic as previously.
    • This is intended to reduce confusion about the end result you will get, and to make it easier to keep a desired element. Now you don’t need to fuse twice to restore your initial element type if you are combining weapons with different elements.

Update 28.3 (2020-08-12)

  • Fixed Valence Fusion failing between Tier 2 Armaments with a "perfect" stat roll and a Tier 3 Armament with a lesser stat roll.

Update 28.1 (2020-07-08)

  • Fixed viewing Railjack Components/Armaments and switching tabs after making a selection not properly deselecting the selected item, resulting in the Valence Fusion and Scrap buttons disappearing.

Update 28.0 (2020-06-11)

  • Fixed Wreckage Capacity not immediately being updated until after exiting and then coming back after using Valence Fusion with Wreckage as one of the components.

Hotfix 27.4.4 (2020-05-07)

  • Changed the Valence Fusion popup if you have no compatible Fusion items but you do have Wreckage partially funded, this popup will indicate that you cannot use partially funded Wreckage for Valence Fusion (you can of course get refunded for cancelling the repair and then Valence Fusion will work).

Hotfix 27.4.1 (2020-05-01)

  • Changed confirmation text when Valence Fusing Railjack components to be clearer.
    • It now reads ‘Choose a stat’ instead of ‘Choose which stat to fuse’.
  • Fixed a script error when using Valence Fusion in the Railjack Configure panel.

Update 27.4 (2020-05-01)

Railjack Revisited (Part 1)

Systemic Changes:

  • The Kuva Lich ‘Valence Fusion’ has been added for built Armaments and Components. Introducing RAILJACK VALENCE FUSION - players can now fuse duplicate built or unbuilt stats to their favorite built parts, boosting them. Based on Public Test Cluster feedback, this no longer requires built Armaments and Components to Valence Fuse: Wreckage can be used, with a resource cost (Max 40%!). Built Armaments and Components can also be used and consumed, with a Dirac cost.
    • Requires Dirac to perform if VALENCE FUSION occurs for built Armaments and Components.
    • Requires Resources and Credits if VALENCE FUSION occurs for Wreckage of Armaments and Components.
    • Combining matching tiers gives 10% boost in stats
    • Combining lower tiers gives 5% boost in stats.
    • Two tiers removed (MK3 with MK1) is 2% boost
    • You can only VALENCE FUSE the same House and type of Armaments and Components across all MKs - much like Kuva Lich Weapons. Also Sigma equipment (your starting equipment or purchased from the Dojo) cannot be upgraded in this way.

Update 27.2 (2020-03-05)

  • Added fancy new FX when Valence Fusion has been successfully completed!

Update 27.1 (2020-02-04)

3. Valence FUSION

First introduced in Hotfix 26.0.6 (2019-11-07), Valence Transfer, now re titled Valence Fusion for clarity, was designed to address owning duplicate Kuva weapons with different unique innate damage bonuses. Giving you the ability to replace a Kuva weapons innate damage bonus (plus investments like Forma, Focus Lens etc) with one from another Kuva weapon was a good start, but we can push this even further!

  • Valence Fusion now also boosts your Kuva weapons innate damage bonus. Examples:
    • Your Kuva Kohm with 25% damage can be fed into your 40% weapon, to make it 44%
    • Your Kuva Kohm with 40% damage can be fed into your 25% weapon, to make it 44%
    • Your Kuva Kohm with 25% damage can be fed into your 44% weapon, to make it 48.4%

Your Kuva weapon duplicates now offer a gradual progression towards a “perfect” Kuva weapon, which would reflect a 60% damage value, if you choose to pursue this path.

We’re also looking at other places we could potentially use this mechanic (Railjack, etc)!

As you can see, we’ve cracked a few eggs to make this omelette! We look forward to your feedback on these Kuva Lich changes!

*PS: It matters which order you Valence Fuse them in. The weapon that you START from, the one where you click "Actions", is the one that will be kept with its investments.

Hotfix 26.0.6 (2019-11-07)

  • Introduced as "Valence Transfer".
