  Sand Form. The sand assassin can move through a 
  space as narrow as l inch wide without squeezing. 
  In addition, the sand assassin can enter a hostile 
  creature's space and stop there. The first time it 
  enters a creature's space on a turn, that creature 
  must succeed on a DC 14 Constitution saving 
  throw. A creature that ends its turn inside the sand 
  assassin's space must also make the saving throw. 
  On a failed saving throw, a creature is blinded for l 
  minute. A creature repeats the saving throw at the 
  end of each of its turns, ending the blindness on a 
  success. 
  Dispersal As a bonus action, the sand assassin can 
  disperse or end its dispersal. While dispersed, the 
  sand assassin is Gargantuan, its space is lightly 
  obscured, enemies have disadvantage on attack 
  rolls against it, and it is indistinguishable from a 
  cloud of dust, but it cannot make attacks and it 
  automatically fails all Strength saving throws and 
  ability checks. 
  Glass. If the sand assassin takes more than l 5 fire 
  damage at once, it partially glasses; its speed is 
  reduced by 5 feet for l minute. 
  Undetectable in Sandstorms. While the sand assassin 
  is heavily obscured by sand or dust, it is invisible 
  and it can't be sensed by blindsight or tremorsense. 
  Actions 
  Multiattack The sand assassin makes two Sand Claw 
  attacks. 
  Sand Claw. Melee Weapon Attack: +9 to hit, reach 5 
  ft., one target. Hit: 18 (3d8 + 5) slashing damage. If 
  the target does not have any allies within 5 feet of 
  it, the sand swirls around it and the attack deals 9 
  (2d8) bonus slashing damage.

  SAND AsSASSIN 
  A sand assassin resembles an athletic human made entirely 
  of sand usually with more sand shaped into cords or rags 
  wrapping around it. With just a bit of dust or sand about, this 
  unusually lawful elemental is easily mistaken from afar for a 
  normal desert traveler, but a good look at its head reveals that 
  it has no face, save for the one hollow eye in its forehead 
  Sand assassins are bound to guard a stretch of land for 
  eternity, hunting down and slaying all those who trespass 
  upon their charge. These elementals sometimes come to 
  decide that a particular place is worthy of protection for 
  inscrutable reasons of their own, but usually they are bound 
  by the one who summoned them, often someone long-dead 
  such as a long-forgotten resident of ancient ruins buried in a 
  canyon or stretch of desert that the elemental still guards. 
  Loyal Sentinels. Often the elemental doesn't recall what it 
  was in the location that it required protection, and rarely do 
  they care to remember, either. For the sand assassin, the task 
  is all that matters. Those that are slain by sand assassins are 
  usually mistaken for victims of a sandstorm, and even those 
  lucky few that escape the reaches of the elemental almost 
  never know what it was, hidden beneath the sands, that they 
  were warded away from. 
  Ruthless Hunters. Sand assassins detest being seen by 
  those who have not yet trespassed and prefer to hide from 
  such beings. In combat, this elemental tries to sneak up on its 
  victims, hiding as a dust cloud or among a real sandstorm to 
  approach its targets, then blinding them with its Sand Form 
  trait before attacking them with surprise. It usually prefers to 
  strike those that are alone so it can deal bonus damage. 
  If it is in melee range with a target that isn't alone, the 
  elemental will seek a target in the fight that is more alone, 
  blinding those that threaten opportunity attacks and flying or 
  burrowing to reach its next lonely victim. If its enemies stay 
  grouped together to avoid the bonus damage, the sand 
  assassin attempts to blind many targets at once instead 
  Elemental Nature. A sand assassin doesn't require air, 
  food drink, or sleep.
