Plating are Components that modify a Railjack's Hull (Health) and Armor. Stats are randomized within a range determined by the item's House and Tier.

Unlike other Railjack Components, the Plating does not have any unique traits.

Houses & Tiers

Plating stats vary between Houses, but the differences follow the same pattern:

• Lavan focused their efforts on superior Hull composition, at the cost of Armor integrity. They are also the only one with a distinct synergy with another component; one possible unique attribute of a Lavan Reactor is a +25% boost to Shield capacity if equipped alongside a Lavan Plating.
• Vidar designed their plating to have the highest possible Armor strength, Hull reinforcement was less of a priority.
• Plating from House Zetki struck a balance between Armor strength and Hull fitness.
• The above implies that best potential effective health (for Mk II-III) can be obtained from Lavan plating. But the effective difference between it and Vidar are virtually all but nonexistent, Leaving both more than enough for the highest level railjack content with and Zetki being the worst choice.

Acquisition

Valence Fusion

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 Credits Credits 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).

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