Blindsight

This spell grants the Blidsight feat. The target creature gains sensitivity to vibrations, so that it maneuvers and fights as well as a sighted creature. The target creatures senses extend to a 30-foot radius, and the creature need not make perception checks to notice creatures within this range. Invisibility and Darkness are irrelevant, though the creature can't discern ethereal beings.

At higher levels: 1 additional creature can be targeted for every additional spell slot above 3rd level.
