If SP were actual magic, I think I'd be just strong enough to maybe make a light bulb blow out. I might be able to conjure a single peanut out of thin air. That's about where I think I am in my journey. I'd be like a kid who doesn't have enough tickets making a sad face at Chuck E. Cheese's (or whatever play-for-tickets and trade them in for toys place is in your area).
I think at about 10,000 SP you'd be looking at the cool powers. Turning invisible. Teleportation. Maybe a little bit of flight in there. You know, you'd really start becoming someone people don't want to mess with.
At 100,000 SP You could raze a city to the ground. Or maybe build one up from scratch. You could walk on water, fly into space and between planets. Turn your best friend into a figurine as a party trick. You could probably have a few laughs with a 100,000 SP in magic power.
At a 1 million SP you could probably create new Earths, travel to other universes, bend space in time....
...You know, I am suddenly very glad that SP isn't actually magic power.
What would your Steem powers be?
