Arcanists and their spells

[Gamma621]

As guildmaster Thubyrgeim put it they are 'esoteric calculations to express the nature of aether in mathematical terms that are represented by arcane geometries.' These are the patterns that allow arcanists to manipulate aetheric energy and produce specific effects. It's also what allows them to shape the aether into summonable entities like carbuncle, the egis, and the fairies.

What I don't understand is how all these complex formulas and spells equate out to things of the biological variety like Bio and Miasma. We get a very clear cut definition of how conjurers and thaumaturges are able to cast the elemental spells that they can. (Nature and harnessing their own inner aether respectively)so why or how do arcanists produce these debilitating poisons and how exactly do they get into our enemies that don't have blood or other things of the biological variety like golems and skeletons and such?

You answered your own question while you were asking it.

If Arcanists/Summoners are able to shape aether into physical manifestations such as the carbuncles or egis, then why wouldn't they be able to shape microscopic manifestations that attack an opponent at the cellular level. They even have a move called "Virus," which means they shape the aether into bacteria to weaken the opponent. Same principal used for Scholars as they manifest leeches to extract disease from a teammate.

I ask because these are things that you would see in the arsenal of an assassin or ninja, not typically a math textbook.

I think you are confusing bio with poison. Yoshida said that the new ninja class will be utilizing poisons, such as weapons coated with Poisonous Potions. Bio implies biological, such as egis, or even bacteria.

After reading through this thread, I think their skills match the class rather well.

Or maybe they shape it into a virus, since that what the spell is actually called? virus =/= bacteria.

Yes, you're right, they're not the same.

Now I could post a link to a fascinating article on the debate of whether Viruses are accepted as being alive or not, or we could skip the biology lesson and continue discussing the game filled with magic and dragons.
