A mod would be great which adds a martyr/died honorfull in battle mood buff. Maybe together with a warrior spirit trait/yautja kind.
So that it would match to an aggressive war band/tribe/clan.
€: but only if fought until death. Not if cowarldly fled from battle and been shot in the back.
or maybe a mood boost if you make piece of art with accomplishments of the slayed one sth like never forggoten
Great idea!
