Lightning Curtain

This spell creates a crackling, shimmering, vertical plane of electrical force. The lightning curtain reacts to nearby metal objects; anyone wearing or carrying such an item will be "sparked" by the wall if she approaches to within 5 feet of the curtain. A "spark" inflicts 1d8 points of damage.

Those passing through the lightning curtain suffer 2d8 points of damage, plus 1 point per experience level of the caster. For those wearing metal armor or carrying at least 4 pounds of conductive objects (swords, iron spikes, etc.), the damage is 3d8 points, plus 1 point per level of the caster.

No saving throw is allowed for creatures passing through the curtain. Touching the lightning curtain with a metal object has the same effect as walking through it. The wizard who creates the lightning curtain is immune to its effects.

The lightning curtain is fairly transparent, allowing persons on opposite sides of it to see each other. Its glow is sufficient to illuminate the area on either side of it up to a distance of 10 feet. Spells and missiles can be cast through the curtain, but missiles must successfully save vs. electricity or be destroyed. The lightning curtain does not hinder any spells except for electrical attacks, which it absorbs.

The lightning curtain will persist for as long as the wizard concentrates upon it, or for 2 rounds plus 1 round per level if concentration is not maintained.

The material components a piece of amber, a bit of fur, and a square of fine velvet.
