I have a problem.

Is it possible to increase passive skill level more than level character?
I can not find a solution to this problem. Max skill level = current character level.
That's interesting. I've never tried to increase skill level past character level.
Is it because of the level requirement graph? You might make a simple stat graph where x=1, y=0 and use that for the level requirement graph.

Nope, I tried different ways, nothing helps.
Well, it seems that I need to return to the standard scheme(with statpoints) because my Passive-system does not work as I need.
gytfunke, I see that you and
RnF have found
a way to change stat bonuses.

It's really-really cool, it's just fantastic.
Can I use your method?
Also, I see that your knowledge about stats are great. Maybe you see a way to make a shapeshifter?
Is it possible to have Duplicate Stats for character stats, skills and points that store a current state of the character and can be used for processes of transformation?
Hey Kva,
Yeah, go ahead and use my method. What I used for RnF's mod is probably what you want. The one for Lure of Ember is more complex because I wanted to add 2 new stats.
For the shapeshifter, I think you could do it.
##Create 'bin stats' for your character's stats that disappear while they're shapeshifted.
I.e.
CHARACTER STRENGTH is the standard stat in-game
BIN STRENGTH is the stat you use to save your character's CHARACTER STRENGTH stat
##Apply the stats via a UI element or a Skill.
Transform
1) If you use a Skill, have it apply the following effect:
----SET STAT (BIN STRENGTH) to STAT (CHARACTER STRENGTH) at STAT VALUE (100) with MIN/MAX=1
2)Make sure this comes after the previous effect:
----SET STAT (CHARACTER STRENGTH) to your desired value.
Untransform
1)Do:
----SET STAT(CHARACTER STRENGTH) to STAT (BIN STRENGTH) at STAT VALUE (100) with MIN/MAX=1l
Barring weirdness with GUTS, that should work.
For the shapeshifter, I think you could do it.

My skill is not as good as you think, but we must try to do it. Shapeshifter - is the main unsolved problem in class creation.
And thank you for your work, you rock!
Oh wow you genius. I always wondered how i could have new stat equal an existing stat value. I could never achieve it through any methods and you have now provided me the method. GENIUS!

Gytfunke found a way, I didn't have much to do with it

Gytfunke, hope you don't mind, but I will link the files here. These files could lead to some good things for others if they were to see them.

@RnF yeah, that's cool man. I hope people do make use of the files.

Lol, Epoch. Have you tried this one already with no luck?
Honestly, I've never even tthought about approaching it this way. You guys are so clever. Moments like these keep my hubris a little in check. Just a little.
