Thus why i wasn't leaning at the spacial dragon concept. Its more of a caster type where its far more limited. I actually thought of that dragon slayer concept first then changed it into more of caster form that help balance behind the powers (in terms of control and energy costs and general limitations that pretty much made them more of an 'anti caster' then an attacker).
Yeah the lightning slayer wasn't a dragonslayer he was artificial, same with the poison one. I'd probably lean at being a real dragonslayer since it does make a rather easy and likable way to have a character being involved. Though i wasn't quite sure if this took part in a similar storyline where the dragons disappeared or what not.
I could go with a water dragon slayer. Could take in water and shoot out powerful jets or maybe create ice. Not sure exactly if the dragon there actually could do both with water of it was separate dragons, don't think they ever said, unless its in the manga. ^^;;
Oh, if you couldn't tell... I say i pick something simple and I'll still take forever figuring out a good element to use.
