Patternweave allows the caster to make sense of apparent chaos. The caster can see such things as pottery shards reformed into a whole pot, shreds of paper formed into a page, scattered parts as a working machine, or specific trails appearing out of overlapping footprints.
After casting the spell, the mage studies seemingly random elements-broken bits of glass,shreds of paper, intermingled trails, etc. The items to be studied must be tangible-coded flashing lights, garbled speech, or thoughts of any kind cannot be studied.
The wizard must study the random elements for one round, after which the DM secretly makes a saving throw vs. spell for the wizard. If the saving throw is failed, the spell fails. However,if the saving throw is successful, the caster sees in his mind the pattern these objects form. If the items studied are truly random, no information is gained.
After the caster has visualized the pattern, he can attempt to reassemble the parts into their original form. This requires another saving throw vs. spell to determine whether the mage remembers sufficient details to accomplish the task. The amount of time required and the quality of restoration vary according to the complexity of the pattern. Reassembling a shredded map may be easy; reassembling a broken clock is significantly more difficult; rebuilding a shattered mosaic is extremely difficult. In any case, the wizard can make only a reasonable copy of the item. He can use this spell to restore works of art, but they will be worth only a small percentage of their original value.
The material component is a small hand lens through which the caster studies the objects. The lens is not consumed in the casting.
