Nope. The current design is cute, no need for any other pretty. Though obviously, that stance can be used for a skill.
Classes named Kabbalist aren’t rare but in English they’re usually spelled Cabalist. That term, however, can refer both to a Cabal or a Kabbalah which can also be written as Cabala or Qabala, especially if the intention is to distinguish it from the Jewish tradition (Hermetic Qabala, Christian Cabala)
The description of the skill doesn’t seem to be related to the name of the class, though. If it really requires you to calculate I wonder whether we’ll also have to remember or identify monster stats, e.g., what does the rolled number represent, id, exp, health, etc., or just play with the number that has been rolled, e.g., when a 13 appeared you can use your Prime skill. I don’t think there will be a lot more complicated interaction as the control mechanics and the speed of the gameplay won’t allow it.
Of course, the class might also be like Ecaflip in Wakfu causing varying damage based on the dice roll.
