Hello all. I've been an avid Final Fantasy XIV player for a few years now, not right from the start but almost, and for the longest time I've been wanting to get into roleplaying. Unfortunately, my sole character is stuck into a data center where, to my knowledge, not much RP is going on, I can't quite afford a transfer and I don't have enough time to handle a second character, but I digress — in the off-chance I can find some RP on the Light data center or eventually transfer, I want to try and establish my character's concept... and for it to be engaging, I think I'll need some help.
First off, a brief summary of the juicy bits about my character: she would be a Veena Viera who left the Skatay Range after a sick/heavily wounded wanderer reached her village (Veena are supposed to be more open towards outsiders than Rava, so I assume it would be feasible?) and died despite her people's attempt at healing them. This would leave quite a mark on her, and upon reaching adulthood she would leave her village in order to become a healer through any means necessary, under the idea that no disease should be incurable. She would find her way to Eorzea, and in particular Limsa Lominsa, drawn by the notions of Arcanima as a school of magic that uses precise manipulation of aether.
Now, my doubts mostly come in regards to the latest bit, as almost all the dedicated healers we see among the NPCs are Conjurers. My character would be an Arcanist, which shouldn't be an issue at all by itself, but the problem lies in how she would use it: rather than focusing on the offensive spells, she would actually use the precise nature of Arcanima geometry - along with basics of alchemy - to specialize in healing. For example, Miasma produces a choking poison in the target's lung, but using the same principles she could use it as a magical nebulizer of sorts to clear a patient's throat of poisons or gases; and I've heard (but I'm not entirely sure about it, so any corrections will be appreciated!) Bio pretty much creates infectious micro-organisms that attack the target, so this could be used to make helpful micro-organisms akin to a magical version of nanomedicine, and so on...
I also thought about having her create entirely new spells. We have multiple examples of NPCs developing their own spells -- but most of them are altered versions of existing spells, and while I like to think my character could learn a Physick II I feel like so much more could be done. I assume a skilled Arcanist could easily do that by drawing up new geometrical patterns to manipulate aether in different ways -- and I think that spells that use lightning-aspected aether to deliver a small shock to the heart like a defibrillator would certainly be very precise, but not outright impossible to develop. Another example would be a clever use of fire-aspected and ice-aspected aether as antiseptics to kill off micro-organisms and achieve a sterile environment.
Of course, all of the above is only useful as long as we don't consider basic healing magic like Cure or Physick and Esuna as able to cure everything. Considering that we see infirmaries (Rhalgr's Reach's comes to mind), I've personally assumed most of the skills we use in battle are mostly just meant to revitalize your allies, knitting wounds and acting as painkillers -- but if a character has, say, a parasite inside of them a single cast of Esuna probably wouldn't cut it, and more in-depth healing would be required. This might also be why alchemists are still a thing in the game world, and under that idea I imagine my character would be striving to act as a bridge between healing magic and alchemy to usher in new medical knowledge.
That was a lot and I'm not really good at explaining myself, but I hope what I wanted to convey is clear. Would such an idea for a character be feasible, or is healing best left to Hydaelyn's traditional means without trying to overanalyze it as if it was a Trauma Center game? I'd like to hear some thoughts and opinions on the matter.
