Distance Distortion

This spell can only be cast when the magic-user has an earth elemental conjured up, but the elemental will not react hostilely to co-operation with the spell caster when he or she announces that his or her intent is to cast a distance distortion spell. 

The magic places the earth elemental in the area of effect, and the elemental then causes the area's dimensions to be distorted in either of two ways: 

1) the area will effectively be one-half the distance to those travelling over it, or 

2) the area will be twice the distance to those traveling across it. 

Thus a 10-ft x 100-ft corridor could seem as if it was but 5-ft wide and 50-ft long, or it could appear to be 20-ft wide and 200-ft long. 

When the spell duration has elapsed, the elemental returns to its own plane. The true nature of an area affected by distance distortion is absolutely undetectable to any creatures traveling along it, although the area will radiate a dim dweomer, and a true seeing spell will reveal that an earth elemental is spread within the area.

Material needed for this spell is a small lump of soft clay.
