As minor creation, except the character can also create an object of mineral nature: stone, crystal, metal, etc. The duration of the created item varies with its relative hardness and rarity:
Hardness and Rarity Examples Duration --------------- --------
Vegetable matter 2 hours/level Stone, crystal, base metals 1 hour/level Precious metals 20 minutes/level Gems 10 minutes/level Mithral* 2 rounds/level Adamantite** 1 round/level
*Includes similar rare metals. Items made of mithral are 50%
lighter than similar items made of steel.
**Items made of adamantite weigh 75% as much as similar items
made of steel. They are also harder and better capable of
retaining an edge, so armor and shields provide 1 higher AC and
weapons allow +1 on attack and damage rolls (although the items
are not magical).
