Burrow/Surface: As a bonus action, Rek'Sai can burrow underground. If a person is within 5ft of a Rek'Sai, they take 1d4 bludgeoning damage and must make a (DC 15) dexterity saving throw or be knocked prone.

Improved Tremorsense: While Burrowed, Rek'Sai loses primary means of vision and gains tremorsense out to a mile. Only means to not being detected is to not move (DC 10 stealth).

Land Shark: Rek'sai moves through the ground she inhabits as if it was water. Making her difficult to track (DC 20 Nature or Investigation). As well as any terrain she moves through is undisturbed.

Tunnel: While burrowed she can use her reaction to make tunnels spanning in one direction a total of 20ft. She can use these tunnels to move without using movement. A target other then Rek'Sai can stand on any of the tunnel openings for a turn to destroy them.

Void Mark: The singe of the void lingers on her claws, marking targets with lingering remnants of the twisted realm she was drawn from. Any target she hits with any attack is marked until the end of the targets next turn.
