Regarding runes: Runes are spells. If you list all the runes in a single line of spells for a creature, they will have them (but with only one use each, after which they will break). I organized the black market for runes in this way, and as a result, I gave one rune to one creature from each faction. For example, human archers can break one stone and gain x2 speed for 1 turn to escape further away (energy rune). I translated the perk "rune refresh" into leadership, and now heroes of other factions can refresh a rune if they have learned the skill.
