Skills

Craft (Int)
Spellcraft:

In some instances the spellcraft skill may be used to actually make something. This will generally be done in conjunction with some other craft skill, though not always. As an example when creating a permanent portal of stone a craft (sculpture) or craft (stonemasonry) is required, but the intricate runes required to make a permanent portal are so precise that a spellcraft check is also required. The DC for a number of such tasks and the craft check (if any) associated with each creationare detailed below. Using spellcraft in this way otherwise functions exactly as though it were a sub-skill of craft.
 * For adding HD to undead the XP reward for the proposed undead is used as the "market price" for determining GP in materials needed, and crafting time.
