Life Sight

At 8th level, you gain blindsight to a range of 10 feet for a number of rounds per day equal to your wizard level. This ability only allows you to detect living creatures and undead creatures. This sight also tells you whether a creature is living or undead. Constructs and other creatures that are neither living nor undead cannot be seen with this ability. The range of this ability increases by 10 feet at 12th level, and by an additional 10 feet for every four levels beyond 12th. These rounds do not need to be consecutive.
