"Yes."

"Fair enough. What's the spear like?"

"It can extend to be up to twelve feet long. It improves your dexterity and running speed. While you hold it, you can jump twice as high, and you are never injured by falls."

"What's its minimum length?"

"About four feet long."

"What are the Tome and the Monocle?"

"The tome, once read, permanently gives you a set of four shadowy, translucent tendrils that defend you against harm, within the limits of their six-foot reach. It also will improve your skill at magic and your general intelligence. As for the monocle, it allows you to see through solid objects and generate harmful rays and orbs of orange light."

"...What other characteristics do these tentacles have?"

"They act independently of you, but always in your best interests, and they can reach through solid matter."

"Can they be tucked away when I don't want to walk around being Tentacle Person?"

"They're still six feet long, but they can intersect your own body. So yes."

"How much control do I have over when? You said they act in my best interests but not how they can tell what my interests are."

"They will do what you want, but can react to things that you yourself have not perceived yet."

"So less like semi-autonomous agents and more like regular limbs with reflexes up to eleven?"

"Somewhere in between."

"So any of the other magic items could end up being taken away, but not the effects of the Tome once I've read it?"

"Yes. They are permanent."

"How would the shadowy tentacles be seen by the general population of those in the new world? How useful is skill at magic?"

"They would be strange and unsettling. As useful as skill with technology is in your world."

"Am I likely to be in combat situations often enough to warrant one of the weapons?"

"Only if you go looking for combat situations."

...

"Are your kind of thing going to be in this world?"

"Yes."

"How vulnerable are you to those weapons?"

"More than to normal munitions."
