This is probably the most important crafting rule.
S-Tier materials
Screws
One of the safest materials to keep or sell to other players.
Screws are currently used by 142 crafting recipes and 4 quests, more than any other component in the recipe set.
They can be produced through Weaponcrafting from:
Bronze Ingot + Iron Ingot at crafting level 1- Iron Hog's Metal Hoof at crafting level 5
They are required across several professions, not just Weaponcrafting.
Launch prediction: Very high demand.
Spool of Thread
Tailoring level 1 converts an Animal Fur Bundle into a Spool of Thread.
Thread is used in 82 recipes and is also required by a crafting quest.
Leatherworking and Tailoring consume large amounts of it.
Launch prediction: Very high demand, especially while players are leveling Tailoring and Leatherworking.
Processed Leather
Processed Leather is currently required by 101 recipes.
It can be produced from:
Lv.1: 5 Leather
Lv.4: 10 Jr. Necki Skin- Lv.6: 10 Ligator Skin
- Lv.9: 10 Croco Skin
That gives Leatherworkers several different farming routes as they progress.
Launch prediction: Excellent bulk-selling material.
Ingots
Do not casually NPC ores or ingots.
Smithing feeds several other professions, which makes metal supply one of the most important parts of the crafting economy.
Particularly useful materials include:
Bronze, Iron, Mithril, Silver, Gold and Orihalcon Ingots.
Mithril becomes especially important because many higher-level weapons and armor pieces consume it.
Gems and Black Crystal
Arcforge converts ores into crafting gems.
Keep:
Garnet, Topaz, Emerald, Sapphire, Aquamarine, Amethyst, Diamond and Black Crystal.
Black Crystal becomes especially interesting later because current Arcforge recipes use it for several stat scrolls and the Gloves Crit. Rate Scroll: Lesser.
