Just a quick rundown of all the skills Sumia has technically learned in my file(s):

( i'll get the next one! )

For RP purposes (where applicable):

Sumia has Galeforce, Relief, Luna, Lancefaire, and Speed+2 for simplicity's sake and the following of canon deal of only 5 skills at one time.

Galeforce and Relief: I tend to play these off as a Second Wind (GF) and normal recovery (Relief) of sorts.
The rest are treated like the skills are explained.
