Alter the amount & distributon of runes after level up

[AncientSion]

I would like to mod the amount and distribution of runes when you level. the hero.txt has the starting values for a new hero and you can change the leadership-on-level, but i cant seem to find a way to alter the amount and / or distribution of runes. Can someone point me to the correct file ?

In addition, does anyknow how leadership gain works ?

// ïðîêà÷êà
level_up {
leadership=20 //60,90


what does it mean ? random value from 60 - 90 and add a guaranteed 20 ?
