Crafting

Obsidian has not yet confirmed the existance or non-existance of this skill in NWN2.

You are trained in a craft, trade, or art, such as alchemy, armorsmithing, basketweaving, bookbinding, bowmaking, blacksmithing, calligraphy, carpentry, cobbling, gemcutting, leatherworking, locksmithing, painting, pottery, sculpting, shipmaking, stonemasonry, trapmaking, weaponsmithing, or weaving.

Like Lore, Perform, and Profession, Craft is actually a number of separate skills. For instance, you could have the skill Craft (carpentry). Your ranks in that skill don’t affect any Craft (pottery) or Craft (leatherworking) checks you might make. You could have several Craft skills, each with its own ranks, each purchased as a separate skill.

A Craft skill is specifically focused on creating something. If nothing is created by the endeavor, it probably falls under the heading of a Profession skill.
