IMPORTANT BEFORE YOU START: Disable the "RPG Overhaul - The New Perk Order" mod
it wipes all specs and only readds the ones in its config. So if you have that mod active
your new spec wont show up.

Basically all you need to create a mod with two ini files and one localization file.
- XComClassData.ini
- XComRPG.ini
- XCOM2RPGOverhaul.int

See more info on creating a mod here https://www.reddit.com/r/xcom2mods/wiki/index

the files and their contents in detail


Add a XComClassData.ini and disable the original class like

(replace CustomClassName with whatever class name you are working with)



Add a XComRPG.ini and add the following entries


* choose an order above 1000
** can be found in the XComClassData.ini of the original class mod
*** placeholder for whatever abilities you want to give the specialization from the original class. Note also add ApplyToWeaponSlot=... entries here if the original ability has them.

You can also make additional configs for mutuallly exclusive abilities, prerequesite abilities or ability-weaponcategory restrictions here. See rpgo or the specops/samurai plugin mods for examples.


Add a XCOM2RPGOverhaul.int file with the following entries



XComClassData.ini

XComRPG.ini

XCOM2RPGOverhaul.int

This is a new property of the X2UniversalSoldierClassInfo class to setup metadata for specs.
Currently its only for random classes and weapon restriction swo but there will probably be more use cases in the future.

The values and what they do:

bUseForRandomClasses - Enables the spec to participate in the Random Classes SWO

AllowedWeaponCategories - This are the weapon categories provided when the Weapon Restriction SWO is enabled

InventorySlots - The weapon categories are supplied to these inventory slots. This is also used by the Random Classes SWO algorithm. Valid values are eInvSlot_PrimaryWeapon and/or eInvSlot_SecondaryWeapon

MutuallyExclusiveSpecs - Define specs that should not be rolled together with this spec by the Random Classes SWO

bDualWield - This specialization can be rolled only as Primary one, and then will provide access to the same AllowedWeaponCategories for both weapon slots.
It can also be rolled as Secondary to a non-Dual Wield primary spec that uses same weapons in the same slots.
It can also be rolled as Complementary to a primary Dual Wield spec, even if bCantBeComplementary = true.

bUniversal - Use to determine whether this specialization is valid to complement other soldier's specializations.
It means this spec can complement any other spec in existence because it doesn't depend on equipment, e.g. Scout (phantom and stuff).

bShoot - this spec requires a firearm to function properly.

bMelee - requires a melee weapon (ripjack counts as one)

bGremlin - requires a Gremlin

bPsionic - requires Psi Amp.

bCantBeComplementary - this spec can be used only as primary or secondary, but cannot complement other specs. "Skirmisher" spec is a good example, as it pretty much requires a ripjack to function.

Weights used by the Random Classes SWO algorithm:
iWeightPrimary
iWeightSecondary
iWeightComplementary
