Wisdom : Convince Hugo to not fight with brothers and rather solve his dispute in diplomatic way in the side quest 'Father Knows Worst'

Honor : In side quest 'Till Death Do You Part' tell the guy that there was no beast in the cemetery
Valor : Complete the quest 'Contract Bovine Blues' by killing skyzard
