A new possible spell "Xavar’s Point Defense" anyone care to comment?
This is my first post on this forum.
Here is a new 3e DnD spell i cooked up, and hoping for any pointers.
Xavar’s Point Defense
Abjuration [Force]
Level: Sor/Wiz 2
Components: V, S
Casting Time: 1 action
Effect: 2 or more disks of force
Range: Personal
Target: You
Duration: 10 minutes/level (D)
This spell creates, mobile, transparent disks of force that hover 2 feet away for you. You create 2 disks and 1 extra for every 3 caster levels above caster level 3, to a maximum of 4. The disks continuously change color and are so transparent that is they do not interferer with your vision. You target one opponent for each disk and the magical guided disks tracks and intercept attacks from the designated opponent. Only one disk can be assigned to a given an opponent at a time. A disk provides you half cover (+4 AC) from the designated opponent and only that designated opponent. The disks do not provide cover against area effects. The disks move out of the way when you attack, thus they do not provide any cover to the target opponent. You can change or set the target of one disk once per round as a free action on your turn, you can do further changes as move-equivalent actions. You must be able to see the opponent when you designate a disk to a target. If a targeted opponent becomes impossible for you to track by visual means, the disk immediately stops tracking that opponent and hovers uselessly out of the way. You do not have to continuously look at the targeted opponents but must be able to see them if you do look in their direction. If something other that attacks by the targeted creatures would connect with the disks, the disks move out of its way. The disks also negate magic missiles attacks from the targeted creatures.
Since the disks provide you half cover from the designated opponents they cannot take attacks of opportunity against you. The cover does not stack with the shield spell.
