"As a warning, try to avoid making too many at once. I developed a mass version of this technique, that knocked me out from memory overload when I dismissed it. 'Too many' is, unfortunately, variable between people."

"I'll work up to it slowly - is there a warning sign when you're approaching too many? Does it suffice if you don't dismiss them all simultaneously?"

"You'll start getting headaches. And that reduces the impact but does not eliminate it; large quantities of clones can also have a domino effect with dismissals, which I believe is mostly due to a hard to isolate flaw in the original technique."

"A domino effect like how?"

"Dismissing one can cause others to dismiss. Usually not all of them, but there's a small risk of it spreading from each additional dismissal."

"Okay. I'll work up to it and see if I get headaches."

He nods.

"I can teach you a few other techniques that seem likely to be both simple and useful."

"Yes please!"

Illusion breaking: theoretically very simple, but can be hard against experienced genjutsu users. Breaking illusions on yourself is slightly different from breaking them on other people.

Transformation: the same technique Tobirama used to change his appearance earlier. Tricky to make it anywhere near believable.

Speed boosts: what they sound like. There's a couple of ways of doing this...

Substitution: the name's deceptive. This actually is a modification of puppet techniques, and pulls an item towards you. If you're fast, you can use that and a smoke screen technique, combined with a simple illusion, to effectively swap places without someone else automatically noticing. This one's the trickiest of the listed to actually get to a usable point.

Cam wants to know what becomes hard about illusion breaking against experienced users. He's not sure speed boosts will be very useful to him unless they work in the air; he can't really... run. The transformation might not work for him because of the whole way daeva self-concept interacts with indestructibility.

Mostly that they're better at compensating for you trying that. You're trying to disrupt the thread of their chakra interacting with your own. They're trying to keep that thread stable.

Speed boosts can involve directly pushing off against things, or making muscles more effective. He should be able to apply the latter to his wings.

Sounds fun!

They're unlikely to get through the basics of much more before other people start stirring.

Well, fortunately, Cam can now be in multiple places at once. One of him can go practice flight speed and one can read things and one can entertain his guests.

Sarutobi has wisely decided to enable everyone else to pretend he doesn't exist.

Sasuke's still moping, but does come out to fetch Tobirama for plans.

"Morning. How are you holding up?"

He shrugs. "I'm functional."

"Better than the alternative. You need anything?"

He rubs at his face. "A planet of sensible people?" Sigh, and: "Probably at some point we should figure out what size library and what contents make a good initial bribe for Orochimaru." That sounds like effort, but possibly less effort than anything social, so.

"Inconveniently that sounds like a job for someone who knows more than I do about local writing, unless he's likely to be interested in science experiments or romance novels or whatever from my worldset."

"He won't be interested enough in anything local, and would also be distracted by a new language. Primers on languages that have a lot of scientific literature... Probably he's most interested in biology and can't do anything anti-social with that fast, plus sensors would pick up on anything he's doing there the easiest. If your world has books on medical ethics that'd be potentially helpful, too."

"We do! Oodles! I can start in on that." He messages the clone who has been assigned to read things.

"I'm - unsure on the balance between 'drowning him in information' and 'keeping some back to bribe him with further.' Though moving through different fields each time we bribe him might keep him entertained..."

"If he's distracted by languages and doesn't learn them in a week apiece then that's years of distraction all by itself. I don't know how many languages you guys have but I haven't even had trouble with anybody's accent yet, here, so I suspect fewer."

"He'll probably get bored eventually without a reason to learn them, but lots of medical journals in their original languages and a primer on each language probably works for years of distractions."

"Shinobi learn fast, and he can make clones too, but I don't think he's that fast."
