Cool, thanks for the input. The devil's in the details, and I want to be as accurate as I possibly can.
I'd imagine it's a combination of prana leakage (especially since a large part of Presence Concealment is matching your emissions with your environment's - I think) and the "weight" of their soul (Gil's is huge, and he's not particularly good at hiding).
Yeah, that does make sense. I suspect the prana leakage is the biggest thing, though.
I'm not sure it's ever made particularly clear, though. Nasu is quite good at that....
Okay, first time I'll be using this thread here, but what would Kariya's chances of surviving the Fourth War be like under either of the following conditions (or both)?
A) Having a Lancer-class Servant instead of Berserker!Lancelot
B) Having had actual magus training while away from the Matou family
Just curious, because of certain details that I'm trying to write into a story, if anything.
In the first case, still zero. Even if he had had no servant at all
he'd have died within a few weeks. Even winning the war couldn't save him (well, unless he wished for it to, which he wouldn't since he needed to save Sakura). In the second case he might fare a little better, but I think the worms would still kill him in the end.
And, having a different servant might make things worse
, since Berserker was actually quite strong. With a weaker servant he'd have lost quickly or, even, been killed by Kiritsugu since he wasn't useful
