When a creature the shadow thief is merged with makes an  Intelligence  ability check to recall knowledge, the shadow thief must make a  Charisma  saving throw. If the result of the saving throw is less than that of the creature\xe2\x80\x99s  Intelligence  check, the shadow thief\xe2\x80\x99s Penumbral Theft ability ends. \n'b'\n'b' ACTIONS \n'b'\n'b'  Claw .  Melee Weapon Attack : +3 to hit, reach 5 ft., one target.  Hit : 5 (1d4 + 3) slashing damage plus 3 (1d6) cold damage. \n'b'  Penumbral Theft . The shadow thief magically absorbs the shadow of a creature within 5 feet of it. The creature must succeed on a DC 12  Wisdom  saving throw. On a failure, the shadow thief merges with the creature. While merged with the shadow thief, the creature\xe2\x80\x99s shadow moves erratically, causing the creature to make  Dexterity  ( Stealth ) checks with disadvantage. The shadow thief can\xe2\x80\x99t be targeted by any  attack , spell, or other effect while merged, but it can be affected by spells like  protection from evil and good . The shadow thief cannot take  actions  or  reactions  while merged, except to Swap Shadows or Coalesce Memories or to end the merge as an action. The merge also ends if the creature is reduced to  0 hit points . An affected creature can be identified as such by their  shadow\xe2\x80\x99s  oddities with a successful DC 15  Intelligence  ( Arcana ) or  Wisdom  ( Perception ) check. The creature can repeat the saving throw after every 24 hours, ending the effect on a success. After three successive failures, the merge lasts indefinitely. \n'b'\n'b' REACTIONS \n'b'\n'b'  Darkness Dissolution (1/Day) . When damage would reduce the shadow thief to  0 hit points , the thief remains at 1 hit point and magically teleports to an area of darkness it can see within 1,000 feet. If it can\xe2\x80\x99t  teleport  in this way, it dies. \n'b'  Swap Shadows . When a Tiny creature the shadow thief is merged with moves within 5 feet of a larger creature, the shadow thief uses Penumbral Theft on the larger creature, which makes its  Wisdom  saving throw against the effect with disadvantage. \n'b'\n'b' ABOUT \n'b' One of the many creations of the unfathomable denizens of the distant cosmos, shadow thieves are small creatures with strangely angular bodies that lie underneath a veil of shadow. Despite the aura of dusk that perpetually surrounds them, shadow thieves are corporeal and remain as such even when they merge with a mortal creature to steal the mortal\xe2\x80\x99s shadow. \n'b' Shadow thieves were initially created to gather information for their alien masters. By assuming the form of different mortal creatures\xe2\x80\x99 shadows, a shadow thief could infiltrate society via progressively more important figures. At least, this was their creators\xe2\x80\x99 intention. However, as the first shadow thieves traveled through the vastness of space, they lost their connection to their elder creators but not their interest in the societies of mortals. Now they wander the planet with their own mysterious designs in mind. \n'b' The experience of having one\xe2\x80\x99s shadow stolen by a shadow thief is not pleasant but stories exist of mortals who form friendships with shadow thieves, willingly allowing the monsters to accompany them on their journeys. For unwilling hosts, the easiest way to rid oneself of a shadow thief is to offer the being a tantalizing morsel of knowledge.'
