I would just want to be a Lightweaver, because particles are waves, gravity waves, pressure waves, heat waves, brain waves... it could do so much stuff! It’s even possible that Investiture comes in waves. I don’t know if Lightweaving can actually do all that stuff, but it would be fun to find out! Also, Soulcasting can also do some pretty fun stuff. Aside from that, maybe I would also want to be an Elantrian, just because I could probably win in an Aon fight with @SwordNimiForPresident, because I have also thought about this, and taken it just a bit further: if one Aon, why not more? Why not have a flat base, and then very thin vertical sheets, as thin and as close as possible, allowing me to stack Aon Rao as many times as I want, maybe combining it with Aon Omi because that also boosts Aonic Power, as well as all of the power boosting modifiers on each of them. Also, perhaps putting the Aons on my Shardplate, too. Basically giving me an insane boost to all my Aons as well as instant Aons at the front of this Shard-Aon-box. I might also want to figure out an Aon that can trigger a perpendicularity, however small, because I might be able to open a little gateway to Sel from wherever, as long as I placed the Aon in the Cognitive Realm. If no such Aon exists, I might have to become an Elsecaller, or some other kind of hacks.
I might also pick Feruchemal steel, just because it can also get pretty fun.
Bendalloy would be nice, I could get things done faster if I’m on a deadline.
Feruchemal brass would be nice, I wouldn’t have to take cold showers to wake myself up.
I could probably find a way to Break a lot of little powers, like Lightweaving, or Soulcasting. (That’s my Smedry Talent, to make things broken. Alcatraz’s is to break things. There is a difference.)
