The aurora horribilis can move through other creatures and objects as if they were  difficult terrain . It takes 5 (1d10) force damage if it ends its turn inside an object. \n'b'  Reality Adjacent . The aurora horribilis does not fully exist in physical space. If the aurora is subjected to an effect that allows it to make a saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails. In addition,  attack  rolls against it have disadvantage. A creature with truesight doesn\xe2\x80\x99t have disadvantage on its  attack  rolls, but if that creature looks at the aurora, it must succeed on a DC 16  Wisdom  saving throw or be  incapacitated  with a speed of 0 for 1 minute. An  incapacitated  creature can repeat the saving throw at the end of each of its turns, ending the effect on a success. This trait is disrupted while the aurora is  incapacitated  or has a speed of 0. \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The aurora horribilis makes two blistering touch attacks. \n'b'  Blistering Touch .  Melee Weapon Attack : +8 to hit, reach 5 ft., one target.  Hit : 15 (3d6 + 5) cold damage plus 10 (3d6) radiant damage. \n'b'  Void Song . The aurora horribilis creates a dissonant song. Each creature within 100 feet of the aurora that can hear the song must succeed on a DC 16  Wisdom  saving throw or be  charmed  until the song ends. This song has no effect on constructs, undead, or creatures that can speak or understand Void Speech. The aurora must take a bonus action on its subsequent turns to continue singing. It can stop singing at any time. The song ends if the aurora is  incapacitated . While  charmed  by the aurora, the target suffers the effects of the  confusion  spell and hums along with the maddening tune. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. A target that successfully saves is immune to this aurora\xe2\x80\x99s song for the next 24 hours. A target that stays  charmed  by the aurora\xe2\x80\x99s song for more than 1 minute gains one long-term madness. \n'b'\n'b' ABOUT \n'b' A ribbon of light flies just above the ground, its gleam flickering in and out of view as it emits a discordant tune. \n'b'  Hidden Among Polar Lights . Though auroras horribilis can manifest anywhere on a world, they prefer to dance and sing within naturally-occurring auroras. When they notice admirers of boreal lights, they descend from the sky to share their songs.\xc2\xa0Unfortunately, they are unaware of the bewilderment their songs invoke in listeners and are subsequently surprised by hostile action toward them. \n'b'  Terrible Harbinger . While an aurora\xe2\x80\x99s direct effects on most creatures is cause for alarm, the aurora\xe2\x80\x99s presence is typically a prelude to something worse. Auroras tend to attach themselves to the forefront of a wave of devastation wrought by unknowable beings. Given the nature of such beings, auroras can precede the beings by days or even centuries. \n'b'  Lessons from the Void . Because auroras horribilis travel with ancient beings from the Void, they hear many secrets about the universe, which they incorporate into their songs. \n'b' An inability to understand the incomprehensible knowledge contained in their songs often induces madness in their listeners. This makes the auroras valuable to apocalypse cults welcoming the beings they herald, as well as to the desperate who seek to avert the coming catastrophe.'
