Ruler Skills are unique Skills that award ruler titles. There can only ever be a single holder of each ruler skill at a time, but anyone can earn them up to Tier 2 LV10 by using skill points or through committing acts of sin and virtue to get the tier one version. The Tier 3 versions are unique such that only one person can have them at a time, and obtaining the skill will unlock the corresponding ruler title. There are currently fifteen ruler skills, with seven being based on the seven deadly sins, seven based on the seven heavenly virtues, and one miscellaneous created by D when Kumoko was disappointed that Appraisal didn't evolve to a new skill.
