Fern's hands.

Fern

Another day of training complete. Now for the most important task...

Fern

Moisturize, exfoliate, repeat. A mage's hands are her most valuable asset.

Fern

Well, second most valuable after magical prowess, of course.

Fern

Frieren-sensei would be impressed. My incantations are precise...

Fern

(And my cuticles are impeccable.)

Fern

Tomorrow, I'll master that new fire spell.

Fern

And maybe land that hand cream endorsement deal.

Fern

A mage's work is never done...

Fern

(But at least my hands will look fabulous while doing it.)
