Benefit: When the magus enhances her weapon using her arcane pool, she may spend 1 additional point from her arcane pool to duplicate the qualities of either cold iron or silver. This infusion does not modify the weapon’s hardness, its hit points, or its weight, but the weapon is considered to be made of the special material for purposes of bypassing damage reduction. Only a single metal type may be infused at one time. At 9th level, the infusion may instead duplicate the abilities of adamantine for purposes of bypassing damage reduction, and for bypassing hardness less than 20 when sundering weapons or attacking objects.
