Interesting, if I could think about it....
Low/Fodder Tiers: At most, somewhere around 9-C to 9-B levels of power. The usual magic in my world (which is actually called Magecraft) would probably be comparable to our world's firearms and maybe a bit more, not entirely positive. But this is mostly just for the average person, which is entirely dependent on a piece of technology to produce these feats. Take it away, they're just average human, if not even less.
A little less than fodder tiers: These guys use technology to enhance their magecraft, and they would usually land somewhere higher up in 9-B thanks to that. I don't think any of them would actually reach any higher tiers anytime soon. About 1% of the population actually do have this type of magic pool without any tech so...still lands them there but with the potential to be higher.
Middle Tier: I would place them around 9-A to probably High 8-C with the protagonist's feats so far, but he is generally higher up in the echelons of the mid-tiers. These guys are pretty much like superhumans in training and, well, I mentioned in my lore document that they can strike with the force of a C4. But the protagonist (mentioned before in the higher echelons) was capable of producing a fireball that was able to melt through a pretty big group of robots and melt through a wall.
Mid-High Tier: Uh, yeah, we're still not even close to the high tiers. But I woud solidly place these fellas in 8-A to somewhere around 7-C or 7-B levels of power. These guys are like the actual superhumans, think of Space Marines for my verse. Incredibly powerful supersoldiers, with a solid one feat one pulling off was a dude capable of clearing an entire storm over a city. So yeah, definitely somewhere around the Multi-City Block to Town, if not, City Levels of power.
High Tier: This is where you would get to see a sudden jump in power. These guys called Paladins, are basically the superhumans to the superhumans, as in, like straight up living legends. This is where you would get to see feats ranging from 7-A to High 6-C, if not even higher to reach somewhere into, like, Low 6-B. These guys have been capable of straight up creating things like volcanoes, creating volcanic eruptions, producing gigantic thunderstorms, and telekinesis that can practically rip apart entire landscapes.
High-High Tier: Yeah, because we're still not done with the Paladins, but this is just reserved for a couple characters. One, a guy named Hedge. This dude would undoubtedly land somewhere in the High 6-B to if not 6-A levels of power just by being able to flip continents with ease thanks to his nature magic. There's also The Chivalry, who are somewhere around Hedge's level of power, if not a possibly a High 6-A rating.
Low-God Tiers: This is more reserved for, like, the primordial humans, ancient guys who are basically what would happen if humanity was capable of reality alteration. Even the weakest of these guys would at least be Low 4-C if not straight up Low 2-C. Basically, one folk was capable of creating an entire segmented pocket of space-time with their reality alteration that had a miniature star within it. Others have been just straight up capable of creating entire higher-dimensional structures (not given much information about what higher dimensions are or how they function) that are at least fourth-dimensional and can contain entirely simulated timelines. Suffice it to say, these guys are like the magic gods. Unfortunate that most of them are all dead.
Mid-God Tiers: Now this is where things get a bit funky, thanks to what The Mystery even is and the path of the Sefirot's nonsense. Honestly, they could land anywhere from 1-A to 2-A or Low 1-C levels of power. To put it as simply as possible, The Mystery is a place always full of contradictions and nonsense, being a structure without any form of reality. Because of this, its size is always changing. In the document I wrote, you can enter as a three-dimensional being, become a one-dimensional dot, and then experience a thousand higher dimensions before popping back out as a two-dimensional stick figure. Now why mention this? Mostly because a singular character does scale to this, a character who reached Atziluth to basically shield the world from The Mystery. Time and Space become meaningless to the Atziluth and they transcend the spiritual chain of descending worlds, of which there are infinite in number. At this point, I have no idea where to scale this.
God Tier/Absolute Top: At least 1-A. Nothing much to say here, the absolute ineffable God that exists above all understanding and notation. It works similarly to the Root from Nasuverse in the usage of Apophatic Theology, where attempting to assign a name and definition to, well, God, only creates a lower-faceted avatar. It exists above all things, unreachable and beyond anything in existence, etc. as the divine creator of all and you get the idea.
Not gonna lie, when trying to scale my verse, it makes it really complicated, thus, the long block of text you see before you.
