While burrowed gain advantage on stealth roles

A monster with Darkvision can see in the dark within a specific radius. The monster can see in dim light within the radius as if it were bright light, and in Darkness as if it were dim light. The monster can’t discern color in Darkness, only Shades of Gray. Many creatures that live Underground have this Special sense.

A monster with tremorsense can detect and pinpoint the Origin of vibrations within a specific radius, provided that the monster and the source of the vibrations are in contact with the same ground or substance. Tremorsense can’t be used to detect flying or incorporeal creatures. Many burrowing creatures, such as ankhegs and umber hulks, have this Special sense.
