Just like in the real world, in Taborea, fashion is everything.
To tailor, you first need to be near Tailoring Tools (See Below). Just look for the green arrow with the thread and needle icon floating above it. Go to "Crafting" in the system menu and select "Tailoring". Then select the item you want to create and the quantity.
An * denotes a dropped recipe
Tailoring recipes for level 11 and above will require the use of 1 Disenchant Rune.
