This potent spell invokes devastation on a localized (and thankfully temporary) scale.

Within the area you choose to affect, the terrain takes on a strange pale hue, as if colors were muted. Periodically, ripples of vibrant color wriggle through the terrain.

Within this area, any spell, spell-like ability, or magic item activation automatically triggers a primal magic event--a spellcaster can avoid triggering such an event by making a concentration check (DC 15 + twice the spell's level), but non-spellcasters who activate magic items have no such option.

You gain a +4 insight bonus on concentration checks made to avoid triggering primal magic events while within an area you have created, and if you do trigger a primal magic event, you may roll d% twice and pick which of the two results you wish to have occur.
