You think for a second about being a summoner of various things, but alas it seems that is outside the spectrum of what magic is here. Maybe a mage? That would be do-able, but everyone you ask says that they would love to share their magic, but due to them being from different dimensions, it is a tribe law to not share magic to minimize injuries. And you yourself aren't magic in the slightest. You will be able to do any physical attacking class, melee/ranged, and you will be able to do some energy based classes, i.e laser gunner.
