Protection from spells

Protection from spells was an abjuration spell that granted resistance to hostile spells.

Effects
Subjects benefit from a much greater chance to resist spells and magic that functioned like spells, but not natural and supernatural effects.

Components
In addition to verbal and somatic components, this spell required a diamond valued at 500 gp or more, which was ground to a powder and tossed over the spell recipient(s).

In addition, this spell needed a focus. Each being to be protected needed to one whole diamond worth 1000 gp while the spell was in effect. If they lost it, the spell ended for them.
