Astrolabe

[Kiirseva]

Has anyone ever seen a price (in any d20 book) for an astrolabe?

I'm looking for suggestions on a price tag and it's benefit (maybe it's just a masterwork artisan's tool?).

[Mr. Friendly]

I would say Masterwork Artisan's Tool, gives a +2 to Survival checks to avoid getting lost, +2 on Profession (Astronomer or Astrologer) checks and +2 on any other applicable check. (i.e. related to the stars for astrological, navigational or astronomical purposes)

[nargbop]

It's a precision mechanical device, but does not require magic to make, only intelligence, patience, and hardened tools to carefully trim the wheels.

I would make a bronze astrolabe cost 100 gp, and make it give a +2 on Survival checks to determine location and astronomy or related checks.

[Sleet]

I'd grant a +2 to Knowledge (arcana) checks related to the stars, planets, or moons. I've seen a magic item astrolabe that 1/week, when used to analyze the heavens, grants a bonus to a save or initiative check as if it were astrological prediction. Can't recall what book that was in.
