For medals i figured it , but thx for checking it yourself.
Raven info is helpful, i`ll check it out.
For spell i wasn`t planing to replace hell breath, but to add new spell (something like 15/25/35% poison dmg to units, for 10/20/30 mana). That`s why i said new bmp AND new place in spell book. Making new spell isn`t big problem, implementing it in game is pain in the ass.
As for rune bonus to units is horrible work, i checked runemage.lng file and there`s relation for his talent and rune bonuses and it`s scary. I had idea to add those bonuses to other units, and after seeing file dropped my silly plan

So i asked if you had any idea how to do it after seeing what you did in this mod. No matter, i hope dev`s will do it in upcoming KB2
Paladins can res 4 units 1 charge, since we can take only 5 units in army (which is fail by dev`s in my opinion, and only 2 reserves

Mass resurrection seems imba, but it`s quite limited in use in battle - must gather units around paladin, then after prayer 1 more turn to move him and cast illusion if needed . . . time consuming, that`s why i said no need to nerf him
