So, I've narrowed down my backup character's class and now I'm looking for the best version of that class to fit the description below. I'm between 3 versions of the summoner. Normal, Master Summoner or Synth Summoner. The DM is ok with any of them.
Vex is around 6 ft as well, athletic build but thinner then the normal. He has short dark blonde hair, faded green eyes and tends to wear a jacket over a simple black shirt and normal brownish pants and leather boots/shoes. Half of the time the jackets sleeves are rolled up to just past the elbows, showing that he also tends to wear leather bracers.He doesn't always have both sleeves rolled up, sometimes he just feels like having one rolled up. He wears a sort of black bandanna with a circular metal plate at the forehead that has a kind of cartoony skull scratched into it. Most of the time he'll chew a piece of wheat or just keep it in his mouth and he also likes to play with various things (daggers, coins. Small items that one could twirl around or play with.)
Vex is the type that would seem like he'd get physically uncomfortable if he stayed still too long. Like I said above, he also prefers to have something to do, such as play with a knife or a coin. He has an odd but generally cheery personality (the kind that could get creepy fast), but can easily turn volatile if angered (which isn't necessarily easy to do.) He sometimes tries to make awkward, creepy, or even embarrassing situations happen as a form of fun inducement and chaos.
Note: He's chaotic neutral and is meant to be fairly crazy, but not necessarily murderous evil crazy.
What kind of summoner do you think Vex would be based off of that description? Any suggestions and why you would suggest it would be great. Thanks in advance.
