Also a tip!

As you know, to equip something, or learn a skill, you right click to use it.

When you buy something from the NPC, (especially skills), make sure you CLOSE the NPC window before trying to use it.

Having an NPC window open while right click will make you sell your item. (usually with weapons and armours it'll ask you if you're SURE you want to sell it, but it doesnt ask you when you sell a skill).
