Equivalence Levels
0 – No Powers
You have no magical powers. Seriously. Absolutely nothing. You're a basic human (or other species that doesn't have magical powers, but, really, humans seem to be the only species that haven't figured it out yet). On the magical level, you're Nat (or a potato, but they're the same thing, really).
1 – What, you call this a power?
I suppose you could call this a power, but not really. It's pretty shitty. You might be able to have better senses - think night-vision, better hearing/seeing, slight healing, maybe even a bit of transfiguration/shapeshifting, or perhaps you could create a little bit of elemental energy manipulation, like setting things on fire. And by "a little bit", I mean "basically nothing". Either way, your power sucks. No, I mean, seriously, it really sucks.
2 – Decent, I guess
I guess you can call this a power. Think very low-tier. You might be able to slowly regenerate, teleport yourself a little bit, do some decent shapeshifting, or maybe actually create more than a match-head of fire. Still not that impressive, to be honest.
3 – Low Superhuman
This is decent. Maybe you can launch a hadouken every once in a while. Your power is still "enhhhh". I don't know what to put for this level of ability.
4 – Below Average Superhuman
Alright, this is your average magic user. Think an average demon's fire power (assuming we're talking about demons that have this type of power). You can manipulate at higher rates, produce stronger attacks, stuff like that. If you have a healing power, you should be able to heal most minor injuries in thirty seconds, and major in minutes (Cannot start regenerating until damage has stopped, AKA if you’re being burnt or electrocuted you can’t begin the regeneration process until you are no longer being attacked.). Things like regenerating a lost limb would still take almost a day and would be impossible in a battle. At this point, you might be able to do a bit of illusionist-type stuff, perhaps a little bit of transfiguration, pretty decent shapeshifting, okay elemental powers, stuff like that. You're a bit lower than the average wizard.
5 – Average Superhuman
Alright, this is a pretty damn impressive power. You can shoot fireballs out of your hands, teleport a pretty decent distance, control elements pretty well (think like, one of the better benders in Avatar, because there isn't really a better way to describe it), things like that. Your power probably won't be too useful against higher-tier supernaturals, but you can slice through your basic human/demon/angel pretty quickly.
6 – Above Average Superhuman
You are a damn good wizard. If your power is healing, you have an amazing healing rate. Your hand is gone? Pfft, that's not a problem. It's back within a minute. Most higher-skilled wizards/supernaturals have this type of power. Your power is dangerous. You might even be able to project (think Loki), reanimate, teleport groups...your power is pretty decent.
7 – High Superhuman
You're...Gandalf. Um, I'm not sure to put for this level. You're better than your average wizard, but you aren't, like, godly. Demigod, I suppose? No, probably a bit lower than that. I have no idea.
8 - Master Superhuman
Teleport is easy for you. Group teleport is a cinch. You can rip holes in dimensions/universe with ease. Energy manipulation? Think along the lines of the Avatar (because my mind is really bad at writing descriptions) - you can do some seriously awesome shit. You could probably make a tornado if you wanted. No, screw that, it would be easy for somebody like you.
