Just as the title suggests, what are the practical limits of free casting?
How far away can you cast? If casting at a distance, is it limited by line of sight? Because theoretically on a high-visibility day, on a flat plane, a person with normal eyesight could cast anywhere between 4 & 10 km.
During S’s training, it was also mentioned that you can distance the output to places you can’t see but can imagine. Is that limited only to places you’ve been to before? Would a photograph, drawing or description of the location suffice?
Could Lacer theoretically cast inside the high crowns throne room - granted it wasn’t warded heavily - while being outside of it? Does he have to be in the immediate vicinity or can he do it from his office?
Does distance become hindered by physical obstacles? Similar to the way WiFi and data can be blocked by large structures or by being underground.
Also, do all wards, whether minor or major, block free casting or can you overpower them? I would imagine there is more danger since you are opposing another thaumataurges will but given Lacers power, it should be possible. Like the way he overpowered S’s divination wards when he free cast a diagnostic divination.
That means to a certain point, depending on the power of the free caster, they can also free cast in areas with wards.
This makes free- casters immeasurably more flexible and more dangerous compared to other sorcerers in my opinion. Other sorcerers need to step into the space to cast the spell so they will trigger the wards anyway or may be even barred from entering but free casters can do it from a distance.
Does free casting past wards trigger them? Is there a way to free cast past wards undetectably? In Lacers attempts, Sebastian noticed but given the nature of her wards I would say it would difficult to bypass them silently. Do wards need to be broken or can they be circumvented of bypassed silently like jumping over a trip wire or something?
This is probably a lot but I’ve been so curious about it ever since I learnt about the mechanics of the world. Free casting just seems so much more inherently superior and has infinitely more utility so it makes sense that it’s so much more difficult to become a free caster that so few people have actually managed it. With it’s utility though, I would have thought there would be more of a push to producd free casters even if the success rate is low.
You can get more free casters if the success rate remains the same but more People actually attempt it. It seems that not everyone thinks they’re even capable or are intimidated by the prospect (the difficulty) of it so don’t even try and never have a chance to find out.
But then again the high crowns are trying to suppress increased power within factions that are not their own.
