Defabricate

You focus a green ray on a creature or unattuned object within range.  Make a ranged attack.  On a hit, you deal 1d4 force damage.  If you miss a creature, but the result is 10 + its Dexterity modifier or higher, you disintegrate part of that creature's nonmagical armor or natural armor.  Roll 1d4, if the result is a 1, this creature takes a cumulative -1 penalty to its AC (minimum 10 + its Dexterity modifier).  A nonmagical object damaged by this spell disintegrates a fist-sized portion into a fine dust.  The DM has statistics for  the AC and hit points of objects.  A magic item is unaffected by this spell.  The penalty to a creature's natural armor is removed if it receives magical heali8ng or heals to its full hit points.  Armor and objects can be restored with the Mending spell or a DC15 skill check by a creature proficient with the appropriate tools.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th (3d4), and 17th level (4d4).
