Switch on is the activation, not the beam of light.
No. Dead end is the activation/true name release, and it's a beam of light

Yes, because her profile is frankly bad and needs an overhaul.
It doesn't, you don't get to just decide on your own that her shield is island level without np release without showing proofs and despite obvious counter feats of not taking every attack thrown at us.
A++ weapon. Invulnerable to anything below an A-rank attack. Need I say more?
You're definitively not saying what you think you're saying. A++ is higher than A (well, equal since it works based on rank), so he tanked it on his durability
If someone is fast enough to overwhelm someone superior in speed, from your logic, then obviously someone slower should be extra overwhelmed GoB spam or not.
Aside from the wrong idea you seem to have that gilgamesh is slower than artoria even though he was winning the one time they fought with their weapons... GoB spam absolutely make someone go from "overwhelmed" to "overwhelming", and even trying to argue otherwise just show how low you've fallen.
Nobody ever says anything about a conceptual advantage most of the time in Nasuverse, Jing Ke only says she's boosted... also Mordred doesn't really give a rats ass about dying either, if she needs to do it she'll do it.
And she and Spartacus were summoned in the lostbelt. Not that it matters, because I was just disproving your lie.
It's relevant in our debate because it basically solves your issue with Jing Ke using a virus on someone who transmitted their consciousness to a computer. She was then caught off guard by Qin not only being able to get around that, but having a grand servant-level body just lying around
It's really not. No need for a skill to hack the sole electronic device of a world. The whole point was that because he is the only electronic device, there's no way he would use an anti-virus or anything like that. But again, that's beside the point anyways in the current predicament, except in making it so that caligula is guaranteed to not lose since Jing Ke HAS to trade her life for his if she wants to win, which is definitively not what you're trying to prove..
