From my previous post (part 2 of a crossover no one asked for)
previous post here!!!
explanations for crossovers here!!!
I already covered status effects, so now I cover actual effectiveness
Spoilers for TWST (Twisted Wonderland) and BT (Blocktales) ahead!
[this format is for blocktales terms] | {this format is for twst terms}
Combat effectiveness:
It would likely depend on how they begin to interact with the BT world. In this case, it will be with a purposeful rift (see my lore post which i will link soon). This entails that the characters are placed in a relatively stable environment (Bizville post time travel).
Because of this, I'd like to double their [SP] drain for now. But the most panicked would be Idia. Most of the characters would likely experience stress from being in a new world, but there's a reason they're in the starting area. Assuming they return to a somewhat stable state, they would be ranked pretty similarly to how they normally would be.
Malleus is obviously the strongest, however several students would be at a disadvantage. Namely students with personalities that inhibit violence, or have {signature spells} that impair or otherwise don't help.
Riddle is the first that comes to mind. Most enemies in BT don't use [SP], which makes his {signature spell} effectively useless. Students with similar struggles would be Azul, Jade (somewhat), Rook, Idia, Silver, and Lillia. Personality wise, Kalim would have trouble with [nooblets] or similarly "cute" enemies. Idia would also have trouble with his avoidance of being outside and any problems. Deuce may also have some troubles, mostly with [noobs] as well as [redcliff knights] [splintered sky knights] and [astral isles mages]. And the [pirates] but he might have less trouble with them.
Some students with a bit of an unexpected edge would include Ortho. Despite not mentioning him in the previous post, Ortho does have guns built into him. Cater also has a small advantage in numbers. Trey could likely use {Paint the Roses} to give buffs that are [removed on strike] to bypass his short effectiveness window. Kalim could play support, but probably wouldn't engage in much fighting in the first place.
I'm not sure how {signature spells} that control people would work, especially since there's no equivalent in the game for obvious reasons.
I am treating all {signature spells} as a fancy buff, spare a few of them that control opponents.
Survivability:
not well. They're in a private school after all
With the already strained relations in the beginning of TWST, I'd assume they'd have trouble working together. Also because they probably are stealing [tix] after battles. Most of them are out of their mirth in survival situations, mostly sheltered students who would be forced to rely on towns and rest stops.
Lillia, Silver, and Sebek could likely survive in the wild for some time. Rook would probably be fine as well.
Other than those few, they'd likely struggle to survive for long periods away from civilization. Since they can't [fast travel] either (presumably) they'd have to plan rations assuming we didn't operate on BT's rules.
Even in civilization Azul's powers are worthless, because no one has {magic} or abilities to steal, spare the few baristas, workers and such. That's also assuming he can even convince them that he has something worth their time, which he likely doesn't other than service.
Ortho is up for debate, since I don't know if he needs to charge or something.
