Deepen Shadows

Over the course of a minute, the shadows in a 10-food cube grow larger, deeper, more ominous and concealing. Brightly-lit areas become dimly lit, dimly-lit areas become dark, and dark areas become menacing. The change is so gradual that it requires a Wisdom (Perception) check, using the caster's Spell Save DC, to notice the casting of the spell.

Any light-based magic cast in its radius will end this spell.

Leveling: The size of the affect area doubles as its caster reaches 5th level (20=foot cube), 11th level (40-foot cube), and 17th level (80-foot cube).
