Do you mean to adjust faction affinity?

I mean "faction traits"

Not sure, if it is right term, in previous TW games, since Rome2, the factions have a traits- offensive, trustworthy, defensive etc

In Troy, one of these trait are Greek or Trojan pillar , all playable heroes have it, and for example Nestor is Greek pillar, Troilos is Trojan pillar, these faction join to Greek and Trojan aliance

Do you know how to use RPFM?

Opem the data.pack with RPFM.
Extract "script/campaign/troy_constants.lua".

Add that folder structure plus file to your mod.pack file.
Edit starting at line 1166:

troy_main_clt_danaans = {
troy_main_dan_arcadians = true,
--troy_main_dan_argos = true,
troy_main_dan_pylos = true,
--troy_main_dan_salamis = true
},
troy_main_clt_trojans = {
troy_main_trj_aegaan_pel = true,
troy_main_trj_ilion = true,
troy_main_trj_imbrasos = true,
troy_main_trj_troy = true,
troy_main_trj_aethria = true,
}

Just add your faction keys there.

I do not.. :/

I want to try

Can You link some link with instruction how to do it/ or learn it? - if it exists

Anyway, thank You for Your answers @Ganossa !

There are some good tutorials for PFM on Youtube.
You can search for Warhammer PFM Tutorials.

They are mostly about database editing, so you can just ignore this, as you are looking for the scripts in the data.pack.
Just extract the correct (above mentioned) script and edit it locally.

Then create a new pack as probably described in the Tutorias and add back that folder structure with the changed file.
