Astronomical chart
Astronomical chart is a members item. No shop sells Astronomical chart and no monster drops it, so an Ironman makes it: it takes 63 Construction and gives 45 Construction XP, using 3 × Bolt of cloth.

Ironman verdict
Where the materials come from: Bolt of cloth (sold by Construction Supplies (Sawmill) for 650 coins). Making ten takes 30 × Bolt of cloth and gives 450 Construction XP. Reaching level 63 Construction takes 368,599 XP in total; the Construction calculator counts the actions and materials to any target, and the Construction guide has the Ironman training route. Astronomical chart is members-only. It is untradeable, so every account, Ironman or not, gets it the same way.
