There are two uses for this spell. You may increase the power of vyord crystals, or you may decrease it.

If you increase their power, the range of the affected vyord crystals' nullification field changes from touch to a 15-foot emanation. Metal or creatures partially in the emanation can spread the field outside of the emanation through touch, just as if they were touching a normal vyord, up to the range of the spell. This power affects both pink and blue-grey vyords, but it doesn't extend the pink's ability to grant creatures SR bonuses.

If you decrease their power, the affected vyord crystals lose their nullification field for the duration of the spell. It also removes the SR bonus granted to a creaure by a pink crystal.

Material component: A scale from a gem dragon, or a vyord crystal (you must overcome the gem's nullification field to cast the spell).

This spell can be affected by permanency. Minimum caster level: 11th. XP cost: 1,500.
