Blindsight (spell)

Blindsight was a transmutation spell that could grant the caster the sense the shape of objects without vision. The spell was utilized by both divine and arcane casters.

Effects
After the casting of the spell, anyone touched by the caster was granted an extraordinary capability of sensing vibrations so well as to be able to fight and move as deftly as a creature with vision. This magical sense extended for ten yards (nine meters)  and lasted for two or more minutes, depending on the power of the caster.

Since it did not require vision, a creature granted blindsight could easily detect invisible creatures or creatures hiding in total darkness, but it did not allow one to sense the presence of ethereal beings. It allowed one to also sense the true location of creatures under the effects of blur or displacement spells, but it did not allow someone to perceive color or read. A creature under the effects of this spell was not prone to gaze attacks or blinding flashes of light&mdash;unless it still had normal vision. Deafening attacks did not weaken the spell, as it relied on felt vibrations, not hearing, but it could not function in a vacuum.

Components
Blindsight required only verbal and somatic components.
