Where are files for passive talents?

[Fatt_Shade]

Finaly i found where to ask this
Can some1 help me out with this idea : i want to change healing abbilities for Inquistor/Palladin/. . . etc to be strenghtend as for Rune mage`s. More unused Mind runes get you more healed/ressurected units.
I wouldnt include Repair to droid`s cause they arent alive (and they are already to strong without strenghtening them
Maybe some1 will think this is cheating to much because neutral units dont have bonus from runes, heroes could but i have no ide how. But everyone use illusion before ending battles to resurect falen units, i just want to shorten that time and dont `Wait` my self to death.
So in the end : what files i need to change and how to get this done. Any help ?

@ Unlucky
As for your hint to change unit resistances : it would be nice to have Royal griffin with 95% all ress, but what happens when you stumble upon enemy stack of them ? This would backfire badly
