Property:Title difficulty is

This is a property for declaring the relative difficulty of a title.

This is calculated different ways for different categories of titles.

Category	Method
Ability	Use the lowest circle which it would be possible to gain the ability.
Skill-Based	Use the lowest circle it would be possible to achieve that title, assuming they trained only minimum circle requirements.
Spell	Use the lowest circle it would be possible to gain the spell, assuming they chose only prerequisits for each spell slot.

After calculating these, use the highest number generated as its difficulty rating.
