Shield

When the shield spell is cast, an invisible barrier comes into being in front of the wizard. This shield totally negates magic missile attacks and provides protection to varying degrees against all other forms of attack. Note that these benefits apply only if the attacks originate from in front of the wizard, where the shield can move to interpose itself.

Note: This version of shield originally appeared in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
