This spell grants the wizard the ability to use sonar to "see" and move safely at a normal rate in the dark, even in magical darkness. The wizard can tell size and general shape of objects up to 10 yards away in any direction he faces. The wizard must actively concentrate to "see" his surroundings, but merely ceasing concentration does not end the spell, and the wizard may resume the sonar again within the spell's duration. The material component is a bit of bat guano.
