The Payload is the Railjack’s stock of certain resources which are used up when the Railjack is in use and is important for the success of a mission.
Once can use this section at the Drydock to replenish each of the resources which cost other resources which are farmable from Railjack missions.
All of these resources may be crafted if you have the required resources needed for crafting them which you will farm over time.
This section may be accessed from the Drydock as well as from the forge in the back of the ship when away in missions.
Revolite
Revolite is a resource that is needed to operate the Omni tool which you need to repair damage on your Railjack.
Without Revolite, you will be unable to fix damage on the Railjack which will eventually end in the mission failing.
Depending on what you are repairing, a certain amount of Revolite is consumed for each time you repair damage on the Railjack.
You can craft 50 Revolite for 5 Cubic Diodes and 5 Pustrels.
Flux Energy
Flux Energy is required to power battle and tactical avionics which is consumed when these are used and by an amount depending on what avionics they are being used for.
Having battle or tactical avionics while running on little to no Flux Energy will render them unusable until more is crafted.
You may freely craft Flux Energy at the Drydock but in order to craft it during missions, you need to have at least rank 2 in your Engineering Intrinsics.
In order to craft 100 Flux energy, you will need 15 Copernics and 15 Cubic Diodes
