The  cambium  makes four Needle Fingers or Poison Ray attacks. It can replace two attacks with a use of Spellcasting. \n'b'  Needle Fingers .  Melee Weapon Attack : +10 to hit, reach 10 ft., one target.  Hit : 21 (3d10 + 5) piercing damage. \n'b'  Poison Ray .  Ranged Spell Attack : +9 to hit, range 60 ft., one target.  Hit : 22 (4d8 + 4) poison damage, and the target must succeed on a DC 17  Constitution  saving throw or become  poisoned  until the end of its next turn. \n'b'  Spellcasting . The  cambium  casts one of the following spells, requiring no material components and using  Charisma  as the spellcasting ability (spell save DC 17): \n'b'\n'b'  At will :  alter self ,  detect thoughts , spare the dying \n'b'  3/day each :  hold person ,  protection from poison ,  heal  \n'b'  1/day :  plane shift  (self only) \n'b'\n'b' BONUS ACTIONS \n'b'\n'b'  Damage Ability . The  cambium  twists the bodily humors of a creature within 30 feet of it that isn\xe2\x80\x99t a Construct or Undead and that it hit with Needle Fingers in the past minute. The target must succeed on a DC 17  Constitution  saving throw or its  Strength ,  Dexterity , or  Constitution  score (the  cambium\xe2\x80\x99s  choice) is reduced by 1d4. The target falls  unconscious  if this reduces an ability score to 0. This reduction lasts until the target finishes a long rest. \n'b'  Imbalance Humors . If the  cambium  has hit a creature that isn\xe2\x80\x99t a Construct or Undead with Needle Fingers in the past minute, it can cause a surge in one of the target\xe2\x80\x99s bodily humors, causing an imbalance. The target must succeed on a DC 17  Constitution  saving throw or suffer one of the following effects of the  cambium\xe2\x80\x99s  choice. Unless noted otherwise, the target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. \n'b'  Sanguine Flux . The target can\xe2\x80\x99t regain  hp \xe2\x80\x94naturally or magically\xe2\x80\x94until after it finishes a long rest. \n'b'  Choleric Flux . The target becomes confused for 1 minute. This effect works as if the target failed a saving throw against the  confusion  spell, except the  cambium  doesn\xe2\x80\x99t have to maintain concentration. \n'b'  Melancholic Flux . The target is  incapacitated  and its speed is halved for 1 minute. \n'b'  Phlegmatic Flux . The target is  poisoned  for 1 minute. \n'b'\n'b' ABOUT \n'b' Unfolding impossibly from beneath voluminous robes, this creature\xe2\x80\x99s pockmarked, spindly arms end in clusters of narrow spikes. Its long, hollow, needle-like fingers and its many-jointed arms move with surprising speed and strength for such an emaciated creature. \n'b'  Hunched and Robed . The  cambium  skulks through mortal society, hunched and contorted, concealing its nine-foot height and its supernumerary arms. \n'b'  Devours Bodily Humors . The source of a  cambium\xe2\x80\x99s  interest lies in every mortal body: the four humors. It drains these from victims in precise amounts, sometimes to fix its own imbalances, sometimes to concoct serums to sell in hellish markets. Its victims are left in a desperate state, eager for a corrective fix and willing to obey the  cambium\xe2\x80\x99s  every whim as servants and toadies. \n'b'  Abandons Victims . After a sufficient crop has been harvested, the  cambium  abandons these addicts to die slowly from violent withdrawals, and allows the local population to lie fallow for a decade or so.'
