This spell allows a priest to animate nonliving chunks of space debris (man-size or smaller) into motion. It is effective in wildspace, phlogiston, and atmosphere alike.
The debris must be present already, not contained by or part of a larger mass. The debris whirls about within an oval area, no more than 10 feet per level long and 5 feet per level wide or deep. The priest can use the field as a barrier or direct it as an offensive weapon. Those contacted by or within the field suffer 4d4 points of damage per round. Exposed ceramic, bone, or glass items in a debris barrier must make a successful item saving throw vs. crushing blow each round or be destroyed.
The debris field moves at a rate of 18 (MC: C). The caster can move the field about within the spell range by concentration. The field remains stationary if the priest casts another spell or is rendered unconscious. A successful dispel magic spell causes the objects to disperse immediately.
Notes: Common for priests from a spelljamming culture; otherwise, very rare.
