Weird

9th-level Illusion
Casting Time: 1 action
Range: 120 feet
Components: VS
Duration: 1 minute

Drawing on the deepest fears of a group of creatures, you create illusory creatures in their minds, visible only to them. The illusion calls on the creature's deepest fears, manifesting its worst nightmares as an implacable threat.

Multiple Targets. All creatures within the area of effect are affected by the spell.

Area of Effect. The spell creates a 30-foot-radius sphere centered on a point of your choice within range.

Save Negates. All targets affected by the spell must make a Wisdom saving throw. If they succeed, the spell does not take hold.

Ongoing Effect. If a target fails the saving throw, they become Frightened for the duration. At the end of each of a Frightened creature's turns, they must make a Wisdom saving throw. On a failure, they take 4d10 psychic damage. On a success, they take half the damage and the spell ends. When the spell ends on a creature it is Incapacitated until the end of its next turn.

The illusion calls on the creature's deepest fears, manifesting its worst nightmares as an implacable threat. At the end of each of the frightened creature's turns, it must succeed on a Wisdom saving throw or take 4d10 psychic damage, or half as much damage on a successful one. On a successful save, the spell ends for that creature, and the creature is incapacitated until the end of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 10th level or higher, the damage increases by 1d10 for each slot level above 9th.
