SQ antimagic cone
Environment Astral Plane
Antimagic Cone (Su): An astral dreadnought's single eye continually produces a 150-foot antimagic cone extending straight ahead from the creature's front. This functions just like the spell Antimagic Field with Caster Level = HD, with one exception noted below. Once each round, during its turn, the astral dreadnought decides which way its eye faces. The astral dreadnought can only make bite attacks against creatures to its front. All magical, spell-like, and supernatural effects within the cone are suppressed, except for those that brought the subject to the Astral Plane in the first place (e.g. Astral Projection spell). These effects are locked in place while the subjects are in the cone and cannot be dismissed, trapping the subjects on the Astral plane while under its effect.
Sever Silver Cord (Ex): If the astral dreadnought can attack an astral traveller's back (by flanking it, catching it flat-footed, or pursuing it while panicked and fleeing), it can attack the silver cord that connects the astral form to its material counterpart. The normally insubstantial cord is treated as a tangible object with the owner's AC, hardness 10, and 20 HP. A silver cord visibly trails 5ft behind an astral traveller before fading into the astral plane. Attacking it draws an attack of opportunity from the astral traveller. When the cord is damaged, the astral traveller must succeed at a Fortitude save (DC13) or be immediately forced to return to its body. Severing the silver cord destroys both the astral form and the body on the Material Plane.
