Shield

Abjuration [Force]
Level: Sor/Wiz 1
Components: V, S
Casting Time: 1 standard action
Range: Personal
Target: You
Duration: 1 min./level
Spell Points: 1

You create an invisible mobile disk of force that hovers in front of you.

The spell provides a +4 shield bonus to Armor Class (which applies against incorporeal touch attacks, since this spell is a force effect). Since it hovers in front of you, the effect has no armor check penalty associated with it.

Augment: For every 4 additional spell points you spend, the shield bonus to Armor Class improves by 1.
