"They let you transmute certain specific things from the right raw materials including more tables."

"Oh, neat!!"

"Yeah, it's a big part of how people do things back home."

"What are the magic metals - I'm not asking for any -"

"Let's see, there's meteorite, hellstone, demonite, crimtane, cobalt, palladium, orichalcum, mythril, adamantite, titanium, chlorophyte, shroomite, spectre metal and luminite."

"...I think at least some of those are normal nonmagical metals but I guess I have no idea why you speak English."

"Huh, which ones do you think are mundane?"

"Titanium and cobalt and I think palladium but I could be remembering wrong about that one, it might be like mythril which I do think is not normal."

"That could be a problem... though the real issue would be if mythril or orichalcum were mundane. Cobalt just makes someone hit harder and run faster when made into armor and palladium does that plus heals you when you hit something animate that you're trying to damage. Other than that it just lets you make really sharp weapons and supernaturally good crossbows."

"I haven't heard of cobalt or palladium doing those. They make airplanes out of titanium, I think."

"You need Mythril or Orichalcum to make anything dangerous from Titanium."

"Huh. So titanium itself isn't magic then."

"I think that depends on what you mean by magic. Refined titanium doesn't have any inherently magical properties as far as I'm aware. But of those I mentioned only Hellstone and Meteorite do and all those do is stay hot. The magical properties come in when you transmute them into things."

"Huh. How hot?"

"They're magically warm, they are a little below the temperature needed to burn someone who isn't indestructible. They're also always a bit warmer than the material surrounding them even if that material is really hot. Their ores are similar except those are magically guaranteed to burn anyone who isn't protected against being burned."

"Huh. I can't really think of a use for that. If they're not hot enough to burn they're not hot enough to cook."

"That's generally the way of things, objects from my world are mostly designed to fulfill a particular purpose or aesthetic and aren't very amenable to uses falling outside those limits."

"Why's that? Who's designing 'em?"

"Most items and the core magic were made by the Logic they're the ones who created the entire cluster of worlds we're from with all their variants. My siblings and I came along after and carved out our own subcluster and added new things and tweaked older ones to be more to our preferences."

"The... Logic?"

"They're a group of people who took a worldseed and turned it into the cluster of worlds known as Terraria."

"A worldseed?"

"All of the world clusters I visited before this one and I suspect this one too are crafted from worldseeds. They're the concentrated potential of a universe. I don't really know how people find them or how common they are. I know me and my siblings came from somewhere else but we lost a lot of our memory as part of the trade for being able to carve out our subcluster. When I spoke to the Logic they've said that they are in a similar situation to my siblings. I guess they could be lying."

"So you're saying God exists, and there are a bunch of them, and their claim to fame is stumbling across seeds and deciding to make something of them??"

"Maybe? That word you're using has a lot of meaning behind it and I don't think it all applies. Creators are people the same as visitors and the instantiated. They don't have unlimited time or attention and they're usually not particularly smarter or more skilled than the average person."
