Anti-magick Field

You create a zone that is divorced from the Mist, supressing magickal effects. Within the sphere, spells can't be cast, summoned creatures disappear, and even magick items become mundane. Until the spell ends, the sphere moves with you, centered on you.

Spells and other magickal effects, except those created by an artifact or a deity, are suppressed in the Sphere and can't protrude into it. A slot expended to cast a suppressed spell is consumed. While an effect is suppressed, it doesn't function, but the time it spends suppressed counts against its Duration.

Targeted Effects: Spells and other magical effects, such as Pulse or Entice, that target a creature or an object in the Sphere have no effect on that target.

Areas of Magick: The area of another spell or magickal effect, such as Fira, can't extend into the Sphere. If the Sphere overlaps an area of magick, the part of the area that is covered by the Sphere is suppressed. For example, the flames created by a Fire Wall are suppressed within the Sphere, creating a gap in the wall if the overlap is large enough.

Spells: Any active spell or other magickal effect on a creature or an object in the Sphere is suppressed while the creature or object is in it.

Magick Items: The properties and powers of Magick Items are suppressed in the Sphere. For example, a +1 long sword in the Sphere functions as a nonmagickal long sword. A magick weapon's properties and powers are suppressed if it is used against a target in the Sphere or wielded by an attacker in the Sphere. If a Magick Weapon or piece of magick Ammunition fully leaves the Sphere (For example, if you fire a magick arrow or throw a magick spear at a target outside the sphere), the magick of the item ceases to be suppressed as soon as it exits.

Magickal Travel: Teleportation and Planar Travel fail to work in the Sphere, whether the Sphere is the destination or the departure point for such magickal travel. A portal to another location, world, or plane of existence, as well as an opening to an extradimensional space, temporarily closes while in the Sphere.

Creatures and Objects: A creature or object summoned or created by magick temporarily winks out of existence in the Sphere. Such a creature instantly reappears once the space the creature occupied is no longer within the Sphere.

Dispel Magick: Spells and magickal effects such as Dispel have no effect on the Sphere. Likewise, the spheres created by different anti-magick field Spells don't nullify each other.

A mage's worst nightmare.
