Wards of Defense - Witch

This potent abjuration creates a stationary force field at a range of 20 feet from the witch, shielding her from any magical attack or physical missile that must pass through the wards. The witch can cast spells of 3rd level or less and fire or throw missiles through her own wards, but no other individual inside or outside the protected area can do so. The spell is stationary, but as long as the witch does not leave the area of effect, she can move about freely. The wards of defense spell does not hinder or deter the movement of creatures, so an enemy can advance through the ward and then attack the witch once inside.

The spell ends when its duration runs out, when it is successfully dispelled, or when the witch leaves the protected area.

The material component is a piece of tortoise shell.
