There exists a variety of skills within FE4, ranging between two types: Class-based and Personal. Class-based skills only exist for that particular type of unit, while Personal skills are related to the individual and can be passed down between generations. Note that the Sword Skills (Astra, Luna and Sol) can only be passed down to non-mounted sword-users.
