Beside the RARE CRAFTING COMPONENTS, the next task we have to deal with in The Lord of the Rings Online are the mastery crafting components. These items or components are used to increase chance of a critical success through the Mastery Option. You have probably clicked few times "Mastery Options" tab in your trade skill window, but it stays unreachable until you complete both the Proficiency and the Mastery or the given tier of the item you wish to create.
How crafting mastery works? There are two different effects of profession mastery depending on whether you're looking at a gathering profession or a crafting profession. When you master a tier of a gathering profession like Prospector or Forester you receive a small chance to perform a "critical" combine while processing items from that tier. On a successful critical combine (about a 5% base chance), you get 3x as many of the completed good as you normally would without using any additional resources.
The other effect of mastery kicks in when you master a tier of a crafting profession like Metalsmith or Tailor. When making items from a mastered tier in these professions there's a 5% chance to make a superior quality version of the item you're attempting. These superior quality items look the same as the base item but usually carry better statistic bonuses and are extremely useful for players of the appropriate level. You can see what the superior quality version of an item is by clicking on the "Mastery Options" tab in your tradeskill window (but only on a tier you've mastered).
This is where the Mastery Items come in. If you open up your Mastery Options tab again, you'll notice that there's an item listed in the box above the superior quality crafted item. That item will usually be an animal body part of some kind, and it's the Mastery Item you need to super-charge your chances of crafting that superior quality item. If you have one of those items in your inventory when you attempt the combine, you can use them to dramatically increase your critical combine chance-- to 44%, actually.
We would like to thank Fizen and company for making a similar list back in the EU beta days (Fizen's Lotro rare crafting components) because it was a most valuable resource in compiling this list.
