I point to a similar skill pair, Underworld Flame and Holy Spark.

Underworld Flame is another split damage spell from Hexer, but unlike almost all of them, it is a single target spell, scaling 100% SWA and 70% Dark/Fire ATK. It can also inflict Burn, a neglected and honestly forgotten status effect that no modern build even tries to inflict.

Holy Spark is a similar one from Priest, though an actual AoE with the same initial target range of both Scarlet Twister and Blood Spike. All it does is shoot with the same 100% SWA and 70% Light/Lightning ATK. That's it. Not even a status effect.

In comparison, Blood Spike is instantly a way better spell, with a staggering 115% split elemental scaling, and applies Claret Call twice without a check, instantly becoming a powerful Ghost tool.

Scarlet Twister gets even stronger with its effective range, also able to apply Claret Call twice, and PULLING enemies too, which means it's unable to be resisted as you're pulled from your position, possibly through cinders (since cinder Ghosts are now becoming extremely prevalent), and take a metric asston of free damage.

Please, for the love of god, make sure Scarlet Twister isn't the best spell in the game with its ridiculous scaling for a very minor drawback in a one turn cooldown and HP damage.
