The Crafting Skillcape reduces the time per action by 0.5s, making it very useful for players looking to keep gaining XP after reaching 99.
Acquiring Materials
Although it is possible to receive Leather and Dragonhides from fighting various Monsters, it is much faster to buy them from the Shop. Leather can be purchased directly from the shop for 100 per pieces, and Dragonhides can be purchased for an amount of GP and Leather depending on the tier. This guide will assume you are purchasing all materials from the store as gathering them via combat will take substantially longer than it would to make the money through other means.
Early Training
From level 1 to level 57, players should make the best leather item they can. Jewelry materials cannot be feasibly acquired in large enough quantities to offer a real alternative, although players who already have Gold Bars and gems on hand may choose to mix them in to speed things up slightly.
From levels 57 to 71, items made out of Green Dragonhide are the most efficient XP/level. Since Green Dragonhide can effectively be purchased from the shop for 200 per piece and items made from Green Dragonhide sell for an amount equal to 200 per piece of dragonhide required, making Green Dragonhide items is cost neutral as a baseline and will actually turn a small profit thanks to materials saved by the Mastery effect.
After reaching level 71, players have a choice: They can continue training using Green D-hide Bodies all the way to 99 while turning a small profit or they can begin creating Blue D-hide bodies and gain slightly faster XP in exchange for losing money. There are three routes from 71 to 99:
