Nothing escapes the notice of your nanites. Your blindsight (vibration)
granted by the all-seeing nanites knack increases its range to 20
feet. This blindsight also extends to any area to which your nanite
cloud has line of effect, to a range of 20 feet. Traces of your nanite
host can even penetrate solid material, granting you the sense
through (blindsight [vibration]) ability, which is blocked by especially
dense or thick materials as normal. Finally, when you apply a nanite
tracker to a target using the all-seeing nanites knack, you can sense
the target as though you had blindsight (vibration) with a range of a
number of miles equal to your Constitution modifier.
You must have the all-seeing nanites knack to select this knack.
