Bow of Light: nope.

Fierce Deity Mask: A cracked and chipped thing which might have once been a painted ceramic mask. It's shaped like a face, but missing an ear and a cheek. It's buried in rocks and dirt. The missing bits are not conjurable. The mask practically crumbles to the touch.

Fairyblade: A large and very colorful sword, with a crystal green blade edged by purple and red. Surroundings are unconjurable. At any radius.

Sagestabber: nope.

"Cam?"

"Mask in terrible condition, can't get the bow or the sage thing at all, the fairy one exists and looks fine but I can't get anything at all about where it is with any zooming out so possibly it's been lost in some kind of planar accident."

"Now, who is that?"

The Deku Tree peers over, insofar as he can emote that when already looming like a mountain over the object and also not able to move.

"An artifact of telecommunication? I have not seen such a creation for... hundreds of years, it must be."

Link pauses if Cam wants to introduce himself.

"My name is Cam, and, yes, telecommunicating from a ship hovering above the forest."

"Few come to Korok Forest in this age, but if Link calls you friend, you are not unwelcome. You must have some form of location magic, I take it? It must be potent, to work long-lost legends as such."

"I can conjure up things, such as the named artifacts or whatever happens to be around those things, but only if it's... things, so the fairy weapon is surrounded by non-things."

"Perhaps the fairies reclaimed their work at last."

"You can make the fairy sword? Does it do anything?"

Cam makes a full size version to give it a swing.

It's a sword. On the light side for how big it is, if Cam has a sense for that, but it doesn't sparkle magically or shoot lasers or anything. If he does some failure testing it's more durable than any ceramic or metal manufactured by Earth, though perhaps not the theoretical upper limits of demon-made designer composites.

"It's light? It doesn't exhibit other obvious special properties but it wouldn't if they were magical."

"Fascinating. You can create true-to-form replicas. But only replicas, it seems, without the magic... even an artifact with depleted power would echo with a presence I can sense. What manner of place do you hail from?"

"It has many names. I usually call it Hell."

"I had not heard of such a place, and I have heard of many," it chortles. "What role do you play, in today's new story? You were not here one hundred years ago, I am sure."

"I was not. If you know Revali he summoned me here."

"Revali... the name is familiar."

"The Rito Champion."

"It would please me to learn more from your mouths, but I can sense that our hero here is getting impatient. If you have more to ask of me, the Calamity threatens more than the smallfolk of Hyrule. I can do little from these hidden woods, but questions I may answer to the extent I can."

"Can you think of a good way to defeat the Calamity with the power to create stuff?"

"I'm going to talk to Hestu. I'll leave the transmitter here. Or will you bring the drone over?"

"I can bring the drone if it will no longer run into invisible obstacles."

Link looks off to the right for a few seconds.

"They'll get out of your way," he says, and he trots off.

"Objects, but not magical effects, do I understand you correctly? I question where the specific boundary lies."
