I was able to mess around with crafting in the Tera Euro CBT last weekend so I took this time to experience and play around with the crafting systems in Tera. So I have attempted to put together a primer on crafting as some of the experience was frustrating before I figured every thing out. Hopefully I save a few people from the pain. As I played a Slayer this time around I mainly focused on leather working and weapon crafting. However these practices should apply to all the crafting save alchemy, which I will touch on briefly. Just follow the link below to view the guide.
Here is a nice little primer guide on crafting from Domeran, the same guy that did the video class guides.
