No need for you to be sorry... it was my mistake.

Hmm... Blue Note did say that he could take Fairy Glitter even from Cana's dead body, so it's clear that at least some forms of magic can be taken from the dead.

The question is if it was something special due to Cana receiving the spell in the form of a tattoo or if it holds true for all kinds of magic. And of course how long the magic lingers before dissipating.
