If I'm following correctly, you should be able to get rid of the
Repeatable, and the Select would work with your many-to-many if it
were named 'skills', but the user will only be able to use it
correctly if you set multiple(1) so they can select more than one item
- or you could use a Radiogroup field instead.

How would you expect to otherwise refer to the 'skill_name'?
[% unique_skill.skill_id %] refers to the My::HeroSkill->skill_id
relationship, and returns a My::Skill
[% unique_skill.skill_id.skill_name %] returns the
My::Skill->skill_name column value.
