Skiller A skiller is a person who doesn't work on combat skills but instead focuses on developing skills such as woodcutting and mining.
You may want to take up offers from skillers if you lack a certain skill (or don't have proficiency in it). Skillers are known for low prices most of the time. However if a skiller is bragging about their skills or money, you may want to exercise the right of "buyer beware!"
If a skiller is handy, you may want to befriend one. They may sell you things at lower prices as long as you "skill" with them sometimes.
