This spell functions as blade drone, except as noted here. Three separate Drones are activated by the spell, which can each target a different enemy. In addition, upon casting the spell, the caster may designate one of three effects to apply to all three drones:

• Each drone is invisible as if affected by a greater invisibility spell at the caster's caster level.
• Each drone can be commanded to explode individually as a swift action, dealing 5d6 points of slashing and fire damage, Reflex save for half. This destroys the drone.
• Each drone also deals force damage. As a force effect it can damage incorporeal creatures without the normal reduction in damage.
