I remember I had an old character that was based on the character Nastu Dragneel from fairytail.
He had a number of abilties including the ability to freeze a spell in midair as it was cast as somsone near him and then to consume the spell.
He also had the ability to drain the magic from magic items to fuel his own spells.
Things I do not remember what class archtype he was pretty sure it was wizard but could have been a sorcerer.
Maybe someone knows?
