It looks like a sheet of glass, but it is more impervious than a sheet of adamantine.
A wall of force spell creates a translucent (but not invisible) wall of force. The wall cannot move, it is immune to damage of all kinds, and it is unaffected by most spells, including Dispel Magic. However, Disintegrate immediately destroys it, as does a rod of cancellation, a sphere of annihilation, or a Mage’s Disjunction spell. Breath weapons and spells cannot pass through the wall in either direction, although Dimension Door , Teleport, and similar effects can bypass the barrier. It blocks ethereal creatures as well as material ones (though ethereal creatures can usually get around the wall by floating under or over it through material floors and ceilings). Gaze attacks can operate through a wall of force.
The caster can form the wall into a flat plane whose area is up to one 10-foot square per level. The wall must be continuous and unbroken when formed. If its surface is broken by any object or creature, the spell fails.
Augment: You can augment this spell in one or both of the following ways:
For every additional spell point you spend, you get an additional 10-ft. square of wall.
If you spend four additional spell points, the wall as a whole does not need to be flat, although each individual 10’ section still has to be.
