When cast, this spell summons 2d10 birds, which are transformed into living stone. The birds are under the control of the caster and retain all of their avian abilities. Each stone bird is treated as a 1 Hit Die creature with a THAC0 of 19. A stone bird has 4 hit points and inflicts 1d4 points of damage with each pecking attack.
Stone birds can be directed to fly into a creature. If the bird successfully strikes a creature, it inflicts 2d8 points of damage and dies.
Birds remain in their stone form for 10 minutes per level of the caster, or until they are killed. At the end of the spell's duration, the birds are no longer under the caster's control.
