Tailor

Tailor is the Dwarf class that makes armor.

To begin your tasks, head over to the wheat field. There, you will kill cows with your diamond axe. Using the leather that the cows drop, you will create diamond armor. By opening your Spell Book and clicking the armor gem (diamond), you will obtain several armor gems depending upon the amount of leather that you've amassed. When you gather several armor gems, you should put them in the nexus by either opening your book and clicking on the nexus, or simply by typing /nexus. Your gems can be used simply by left clicking with them; no further crafting is required.

Currently, there are two legendary items from Tailor. Both are spawned from the "cube of potential," which randomly drops from cows. It may be seen floating on the back of a cow so that it can be targeted. One of the legendary items is an unbreakable diamond chest-piece that will slowly deteriorate over time. The other is a heavily enchanted golden chest-piece, but it will rapidly break.

tl;dr:

Kill cows, make armor gems which spawn diamond armor from your Spell Book and leather, and put it in nexus. Two legendary chest-pieces spawn from the cube of potential which is a random drop from cows. To use a gem, left click with it.
