Create an XML file in data/npc:

<?xml version="1.0" encoding="UTF-8"?>
<npc name="Old Blacksmither" script="name_of_the_script.lua" walkinterval="0" floorchange="0">
        <health now="100" max="100"/>
        <look type="128" head="17" body="54" legs="114" feet="0" addons="2"/>
</npc>

You can change the look of the NPC by changing the numbers (outfit looktypes,and colors):

<look type="128" head="17" body="54" legs="114" feet="0" addons="2"/>

To configure the recipes,change the table below:

local recipes = {
        [2390] = {
                {2157, 1},
                {2400, 1},
                {2149, 100}
        }
}

Always follow table structure by placing a comma at the end key "}" except the last.

13:44 Zysen: hi
13:45 Old Blacksmither: Hello, Zysen. Actually I can trade rare stuff for some items, pretty, heh? This is what I have: magic longsword
13:45 Zysen: magic longsword
13:45 Old Blacksmither: Good choice, I will need 1 gold nugget, 1 magic sword and 100 small emerald. Agreed?

Yours,
Zysen.​
