Now to veer off to a very different but similarly painful scaling-related topic: Tier Jumps.
Why tier jumps? Because as much as it pains me as a fan of hard magic systems, sometimes characters just become thousands of times stronger overnight for no real reason. Looking at you, every JRPG ever. You and your
Cloud Strifes jumping from Wall level to Multi-Continental just by getting emotional. You and your
Luminaries going from City Block level to Universal+ in between Acts. All the
Ren Amamiyas going from Continental to
Outerversal just by getting really
really motivated.
Suffice to say, I've given up on the bullshit. Honkai Impact 3rd and Honkai Star Rail have both feats and statements, and it just makes the most sense at this point to stick to both of them. Because, even when feats top out at Tier 6 while statements go up to Tier 4, when viewed through the lens of the JRPG genre that Mihoyo is very obviously inspired by (just look at their surveys for HSR), they're actually kinda
consistent?
Take a look at Honkai Impact 3rd. Most characters scale to people like Siegfried or Sirin or 2E Welt Yang, who all have a fairly consistent scaling from calcs yielding 6-A and High 6-A results. Meanwhile, the top tiers all scale to feats such as creating and moving stars, rivaling supernovas, and destroying worlds. At first glance it would seem odd to bridge the two extremes together. That is, until you take into account that the characters that these top-tier feats all apply to are consistently portrayed to be in a league of their own.
Destroying worlds and
rivaling supernovas are attributed to Kevin, who consistently bodies every single character that ever fights him all the way until the final battle of Part 1, where he fights the strongest forms of the protagonist trio in Kiana, Mei and Bronya. Even when fighting characters that are hyped up and are able to minutely hurt him, the instant he got serious, he
blitzed,
one-shot and
vaporized Senti - one of the strongest characters even up until the endgame. And Elysia, who the "
creating and
moving stars" statements are attributed to, is consistently portrayed to only be a little weaker than Kevin.
So tiering wise, as long as the character in question is directly compared or reasonably scales to another character that scales to 4-A, and is consistently presented as being in a league of their own compared to everyone else who scales to 6-A, then it shouldn't be a problem to scale them to the former tier.
