Dancing Shadows

A roiling mass of leaping, dancing shadows surges into existence at a point you choose within range, creating a 10 foot radius sphere. The area within the sphere is lightly obscured and light sources have half their normal effective range while inside.

Additionally, creatures within the sphere can take the hide action, potentially concealing themselves from creatures outside the sphere. Finally, creatures in the area of the sphere have half cover; if the spell is cast in an area of dim light or darkness, however, this instead becomes three-quarters cover.
