So uh, it'd be up to Hantu in the Ryuudou Temple posting cycle I guess? If we have one?
For some reason, I vaguely recall the command seals throbbing at the presence of other masters or some other way of detecting them but since I'm not 100% sure I've left it out of my post to avoid uninformed meta. hmu if I'm wrong there and I'll edit in being jumpy and unsure instead of just waiting to see what happens.
Yes, once the Servants are summoned and the CSs materialize properly, they'll burn while in the presence of another.
…
The Command Spell engraved on my right hand is hurting.
A small warning as if to get my attention.
"Someone's watching us."
"Hm."
I extend my consciousness to the surroundings.
I roll out the threads of my consciousness and search through the park
“… I can't find him.
What about you, Archer?”
"It's difficult. I can't even feel the stare."
"…Then, it must be a Master watching."
I don't know who it is, but if Archer can't sense it, it has to be a Master.
"…The Command Spell reacts to other Command Spells. So that must mean that if you are a Master, you should be able to recognize other Masters when you see them. Then wouldn't that mean you should be able to identify the other Master too?"
"Yes. But a superior magus can conceal their magical energy. Even though Command Spells react to each other, they operate on magical energy. If the Master has closed his Magic Circuit, it will be hard to find him."
"…That's troubling. That means we are showing them our location."
"That's right. Well, if I search around my house, I should be able to find something that kills my magical energy, but…"
Is it ok if I finish that other CS later and then try to steal and then try to steal some low-life's command spells? I think this would be a good dick move for pseudo-Kayneth-chan.
Sure.
