For some of the skills there may also be a section showing alternative routes, for where some items might be difficult to acquire, and other items might need to be made in order to skill up. After that there is a table of items which are needed, but are made using another Trade Skill. Lastly there is a table of useful items that can be made, and are required by another trade skill.
For instance, if I am making an arrow that will go trivial at 162 I might make them until my skill is around 157, and then move on to the next highest trivial arrow. Also, when I have been following guides to help me with my trade skills, I sometimes skip certain stages that would not gain me many skill points, or where I would find it difficult to get hold of some of the items.
For instance, if my Fletching skill were 36 (arrow gone trivial) the next numerical step I could take would be to make the 46 trivial arrow. However, as I am near the trivial mark I skip that type of arrow, and move on to making the 56 trivial arrow instead.
The guides here reflect the choices that I made on my way to mastery. There may be some items in between two trivial levels that can be made, but I didn’t use them, so they are not here. I chose the quickest, easiest and cheapest routes I could find, and as has been said before, there is no definitive list on this site of every item under the sun that can be made.
Hopefully my guides will be of good use to people wanting to get their skill up there as efficiently as they can, and hopefully to others aswell. If you have a doubt about something, or wonder if there is a step you feel you would rather do please visit the links section where there are many fine websites listed that can help you in your quest:)
