Rolling it

Nothing is guaranteed. At the start of each battle a unit's primary job rolls every ability it knows, one at a time.

As your primary job: 75%
As a sub-job draw: 60% of the bucket

Roughly one unit in 150 skips the roll entirely and fields its whole catalogue. If a unit rolls nothing at all, it is granted its cheapest ability rather than being sent out empty-handed.
