You can warp everything a creature sees into a hellscape full of terrible creatures. When a creature fails its saving throw against your Hex: Hallucination cantrip, you can further distort its mind. The creature has the Frenzied condition. A creature with the Frenzied condition loses the ability to distinguish between friend and foe, regarding all creatures it can see as enemies. While Frenzied, the creature chooses the targets for its attacks, spells, and abilities randomly from among the creatures it can see within range, and it must make an Opportunity Attack if any creature provokes one. The Frenzied condition ends after 1 minute, or when the spell ends.
Once you use this feature, you can't use it again until you finish a Short or Long Rest. You can also restore your use of it by expending a level 2+ spell slot (no action required).
