You unleash a russet ray at a metallic object.
The air around you smells of hot metal.

This russet ray corrodes metal that
it touches. You must succeed on
a ranged touch attack with
the ray to strike a target.
It can effectively destroy
any nonmagical iron
or iron alloy object.
Such objects struck by
a rust ray take 2d6 points
of damage +1 per two
caster levels (maximum
+10), ignoring hardness.

You can also target a weapon
being wielded or metal armor
being worn. Metal armor affected
by this ray takes normal damage
from the spell and loses 1d4 points
of Armor Class through corrosion.
If an item is reduced to 0
hit points, it is destroyed. Ferrous
creatures struck by the ray take the
same damage as objects.
Magic items can negate the
effect with a successful Fortitude
saving throw.

Material Component: Rust particles
or a piece of a rust monster.
