Cthulhu's Boon

You summon 2 writhing green tentacles at points of your choosing within range. Including you, any creature within 5 feet of either tentacle must make a Dexterity saving throw against your spell save DC or take 2d8 bludgeoning damage per turn that they fail the save. All creatures including you within a 10 foot cube of either tentacle must make a Wisdom saving throw or enter the effects of madness. Any creature that enters the spells area of effect must make a Wisdom saving throw including creatures that have already passed the save. If a creature has passed the Wisdom saving throw and does not leave the spells area of effect they are temporarily immune to madness until they leave the spells effect range.

Roll a d6 to determine the effects of madness for every creature under the effects of madness. Different creatures can react differently to the spells effects.

1) They fall into fits of hysterical laughter. The creature falls prone, cannot move, attack, or speak. This effect ends if they take damage or the spell ends.

2) They must attack all living creatures that they can see. If they are unable to reach a creature to damage it, they begin to attack themselves. This effect ends only when the spell ends.

3) They feel compelled to eat any and every non living thing that they can see. This effect ends if the target takes damage from any non ingested substance or if the spell ends.

4) They see 1d4 horrifying images around any creature that they consider an enemy. If they move towards these images they take 1d6 psychic damage per horrifying image that they see.

5) They hear deep chanting in their head known only to them. They lose the ability to hear and cannot cast concentration spells. This effect ends once the spell ends.

6) They feel inebriated and have disadvantage on attack rolls.
