Does the Lyre of Building require the materials to be on hand?

Or does it summon the materials that you need to create whatever you wish?

[Klebert L. Hall]

It's a Fabricate effect, so I would say that you need some sort of raw materials, but they could be anything. The Lyre then converts them into whatever you're building.

That isn't a rule or anything, just my take on it.

The base spell is fabricate so yes you do need the materials. The other clue is that item uses Transmutation magic, not Evocation or Conjuration which brings things from nothing or elsewhere, repectively. What the Lyre does, is save on labor and a lot of time. An advantage it has over fabricate is that it's not dependent on Craft checks.

Need materials on hand, but it could (in theory) tear down one building to build another.

This is really an "Ask your DM" question, since I just gave you my answer I'd use in a PFS game if a player used it.

The lyre is crazy powerful if you could somehow play it for several hours straight.

In three hours you have done the work of 100 humans working for 18 days. Couple with a few unseen servents and a real work force..

You have a priest cast lessor restore on you every few hours and you cn get 10-15 hrs in easy. 15 hrs =3 months of work. 4 x a month =1 yrs work in a month.

It's crazy powerful even so!

Interesting, but is it the musician that needs a rest before it continues playing, or is it the instrument?

The lyre can be used in this way once per day... Once a week, its strings can be strummed so

The description of the item does not seem to specify that it the limitations on playing are due to the player and not the instrument.

The instrument has 2 basic functions. It negates damage to inanimate objects, and it does construction-labor.

I don't think any materials are required for the negate damage to your castle or ship. It seems to make the ship just repair itself like a Borg Cube.

There is no material component for performing labor, but the laborer needs materials to work on. That being said, aren't there nearly always materials on hand to build things out of? If there are no trees to cut down, are there reeds to bundle together? What about the ground itself? can't you mix water in with the earth itself to make clay? Is there no rockbed to cut into? Can't you just dig into the ground itself and make tunnels and ramparts?
