If you could be any kind of Mage in Fairy Tail.. who would you be?

i would be sting bc im sting

The Lost Magics. I find it fascinating ^^

Dragon slayer because I want to eat fire (im an arsonist)

Well if you're still interested if I can only use one magic it would be using divine blue flames magic. Divine flames cannot physically burn the flesh of the living but it can either give the sensation of warmth from a mother or feeling like it's actual fire depending on the sins that weigh on one soul. However when it comes to demons undead and such it seers them down to the bone and turns them into ash.

Intresting question... And something like Necromancer... Being able to summon countless undeads, demons, monsters who can be revived again after being defeated! Just imagine how broken it would be to not do anything and make them do all your work lol
