Call to Beyond

You channel an intense torrent of magical energy into a nearby creature, lighting it up as a beacon to extraplanar creatures. You spend an hour channelling magic into a creature you can see, this channelling as well as the spell when fully cast is obviously present to divination spells that reveal magical presences such as detect magic. At midnight, every day that the spell is active roll a D100, the creature suffers the following effects.

• 70-100: The spell ends automatically, with a wave of energy emanating visibly from its eyes and mouth.
• 50-69: The creature is favoured by a strange entity, they gain advantage on death saving throws for the next 24 hours
• 30-49: The wracking energies of the spell cause the creature to undergo painful convulsions, it takes 4d4 psychic damage after which it has disadvantage on perception checks for 24 hours
• 25-30: The creature is a magnet to magical effects and enchantments, all newly casted spells that have a target casted within 30ft of the creature instead target the effected creature.
• 20-24: The creature acts as the host for 1d4+4 Imps, Quasits, Sprites, or Mephits for 1 hour, these creatures will not act with hostility towards the creature, but are not under its sway.
• 15-19: The creature begins to perceive mysterious visions and forces within their sight, they gain Truesight of 30 foot distance but are plagued with nightmarish omens.
• 10-14:The creature immediately splits into two the next time it falls unconscious, with the duplicate formed being akin to the Simulacrum Spell.
• 1-9: The creature is seen from a dark horror from beyond, whom attempts to manifest. The next time the creature falls asleep its body serves as a portal of its dimensions as described in the Gate spell to a random location in the far realm for 1 hour, at which point the spell ends.
