Alter the amount & distributon of runes after level up

[BigBoogerBot]

Look in logic_hero.lua

Scroll to about half way. You're looking for

rune_war={"6,4,2","5,5,2","6,3,3","7,4,1"}
rune_pal={"3,6,3","2,7,3","3,5,4","4,6,2"}
rune_mag={"2,4,6","1,5,6","2,3,7","3,4,5"}

Those are the runes you get per level. Just increase the numbers
