Since the game updates monthly you'll likely restart at some point the console commands below make it easier. I'm sure there's more but they're the only ones I found in the thread.
all_actors[u'alexia'].coruption=X
all_actors[u'alexia''].relation=X
castle.treasury= x
avatar.gold=x
avatar.exp=x
avatar.mp x (map movement)
castle.rp= x (research)
For Rowan's corruption, there's the first code, and the second to check what it is at the moment:
change_base_stat('c', #)
avatar.corruption
And this for setting the influence twins have with Alexia:
all_actors[u'alexia'].flags['jezera_influence'] = #
all_actors[u'alexia'].flags['andras_influence'] = #
There's also one to add influence you have on the twins, which I THINK would be this, but I apparently lost the readme it was in and I can't remember how to call the number to check it like with Avatar Corruption, so may not work but doesn't provide an error at least?:
change_favor('jezera', #)
change_favor('andras', #)
I think that covers everything you might want to mess with (except maybe guilt, but at least right now there don't seem to be too many reasons to fiddle with it)? Although from testing just now, you just replace the corruption codes with g and guilt, so, there's that too.
Edit: Completely forgot that the other characters also have their own relation scores now:
change_relation('cla_min', #)
change_relation('cliohna', #)
change_relation('skordred', #)
change_relation('draith', #)
change_relation('xzaratl', #)
All of those seem to work, but Indarah and Shaya don't seem to have relation scores yet. One assumes when they do, it'll just be replacing the name, as all the others were.
