Crafting
To craft, a monster must be sent into the Wondermine for a chance to gain a number of Wondermine-exclusive Crafting Items such as this. Sending more elementally complex monsters will gain a higher chance of obtaining, up to a maximum of 100%. For this Crafting Item, using a Quint-Element Monster will give an 32% chance of a single per sending. Sorry, but no monster can give a 100% guaranteed chance for this Crafting Item.

Purchasability
It is extremely difficult to purchase Copper before another player purchase it. If you need Copper, purchase Copper as soon as you see a Copper icon in the Market without hesitation.

Sellability
It will sell very quickly when advertised, regardless of price. It will even sell if you do not directly advertise it and/or players spy on your Market.

Skyship requirements
The Skyship requires three sets of three orders of a number of Crafting Items per shipment. For every order, a certain number of Crafting Items is required. is the utterly most difficult Wondermine-exclusive Crafting Item to obtain, so the Skyship may ask for 3 orders of 1 to 2 per order, summing up to 3 or 6 per shipment.
