So, I been curious and I wonder if you have answers; how strong is Idia? I know physically that a new born kitten could woop him, while technology wise not even the master control could stand against him, but what about magic wise? And where does he stand in comparison to the other dorm heads? I know in ch 6 he was strong as heck but isn't that mainly because he was getting energy from the blots?
(Thank you for your time)
Mmm, well... I don't think "magic strength" alone accounts for how good of a mage someone is. You could have all the power in the world but could be a terrible mage just because of how you use it (like if you lack control), or perhaps because you can only cast a few powerful spells before you blow through your energy reserves. All spells are also not made equal; there are defensive spells, offensive spells, healing spells, and more! Because of all that, it's hard for us to really quantify how "strong" a mage is, because really each mage seems to specialize in their own skillsets. It's not "which class is the strongest?" but rather "which class fits your preferred play style?" For this reason, I'm not going to be formally ranking the dorm leaders but instead will point out their strengths and weaknesses.
As Idia points out in book 6:
Riddle has an artificially large magic pool because he started his magical training from a young age. He is capable of casting strong spells and favors offense, but also has low physical stamina and tires easily (from blot accumulation) because he tries to brute-force. His mental state is also said to be heavily impacted by external factors.
Leona can cast spells quickly and effortlessly; his magic pool is described to be "huge", but we don't know how this really relates to the other problem children in terms of scale. He also seems to boast precision, as he can "tailor" his defensive spells' strength to counter his opponents. Because of how efficient Leona is, he barely accumulates unnecessary blot. Stress does not have much effect on how fast he produces blot, but intense emotions do cause a significant spike in him. Additionally, Leona is skilled in flight due to playing magift/spelldrive.
Azul is a relatively slow spellcaster but makes up for that with precision and access to a variety of spells. He watches the flow of a battle, keeps cool, and then plays support/heals as needed. Idia also notes that while Azul can cast many different spells, Azul also does not have a large enough magic pool to support them and so has to be more careful about what and when he uses his magic.
Vil is very stable across the board and is quite resilient to blot. Stress does not have a huge effect on him, but the blot does seem to stick around for longer because of his larger magic pool. Something else to keep in mind is that Vil excels in making potions, which is another form of magic.
Please keep in mind that these refer to mainly COMBAT scenarios, which are not the only cases in which you would use magic... so this isn't an entirely accurate assessment; it's just the most convenient assessment since the game blatantly lays the comparisons out for us. Let's now piece together what we know of the remaining dorm leaders based on lore we have:
Kalim does not strike me as someone who has a particularly large pool of magic (it's never commented on, nor shown). I'd place him at around normal until otherwise refuted by the canon. We know he's not particularly proficient in his studies, as he just barely scrapes by in classes with intense help from Jamil. This may not always translate to poor performance in practical settings, but we also have no standout moments of Kalim pulling off impressive spells or being a notable mage. He also doesn't seem to be aware of the practical or strategic uses for his own UM unless others in his immediate vicinity are in need of large amounts of water. It's possible that he's incredibly powerful, but lacks awareness of how to best utilize his magic.
Malleus is stated in the lore to be one of the top 5 mages in the WORLD. He uses magic on a daily basis and barely blinks an eye to when he does amazing feats like STOPPING TIME ITSELF. Book 7 also reveals to us a hypothesis that fae might have access to an essentially limitless reserve of magic because they pull that magic from nature itself. I'd say that this definitively places Malleus at the top of the "magical power" hierarchy--there was never any doubt about that, the problem just comes in trying to sort everyone else under him.
And then there's Idia, whom we don't really see performing magic much by himself. No, he prefers to tinker with his computer parts which, technically, can count as magic since technomancy is the combination of technology and magic. (Does Ortho count as something resulting from Idia's "magic power"??) It's hard to say.
If I had to guess, I would think Idia is another stable user like Vil but is also highly volatile like Riddle (due to his guilt and grief being the main source of trauma). Idia HAS to cast spells or input magic into his devices because of his curse; if he does not accumulate blot, there's nothing for his curse to dine on... so it'll dine on his own magic instead, which can be detrimental to his health and wellbeing. (This is why the Shrouds are perfect candidates to work at STYX and research blot. All the blot present in STYX HQ fuels them and feeds their curses.) This implies Idia has to have output, and consistent output at that. More blot present in the immediate area may be able to power him up more and allow him to cast more spells/cast spells more frequently, but that's again highly dependent on his environment. Idia has the "flexibility" that the other dorm leaders lack, which can be a curse or a blessing given the scenario. Make of that what you will!
