Range: visual range of the caster
Casting Time: 6
Duration: special
Area of Effect: 30 ft cube
Saving Throw: neg.

Following his excursion into new spell areas of effect with the Force Helm, Otiluke sought to expand his repertoire and gain experience of channeling from the Para-Elemental Plane of Ice with this spell. While having several combat uses, it was intended for other purposes and Otiluke is said to have been disappointed with the result. Spheres and screens have occupied his attention since.

This spell causes the caster to project a magical ball that will magically freeze the ground within a 30-foot cube. All in that area must attempt a saving throw or be frozen for a duration totally dependant by the success made by the creatures' saving throws. A victim is not harmed but is open to deadly attacks as he waits helpless.

The cube will hold those that failed vs. spells at the following modifier:

* -6 for 1 round
* -5 for 2 rounds
* -4 for 3 rounds
* -3 for 4 rounds
* -2 for 5 rounds
* -1 for 6 rounds
* No modifier for 7 rounds
* +1 for 8 rounds
* +2 for 9 rounds
* +3 for 10 rounds
