I'm very much interested in this, too.
Peace of Mind (/Burning Eyes) is an example for a buff that increases its numerical values over time. I'd like to replicate this for other buffs but can't find what makes Burning Eyes scale with lvls :o
I think base damage per level scaling is mainly linked to the vitality scaling modifier within data. As far as I know there is no option to adjust scaling for specific skills in detail except for changing the 'Damage' column which offers a bunch of options. Although I have to admit that I didn't explore these options in detail and don't know if they are useful at all.
