Dungeons & Dragons 5e Element 133 Class Feature: Psychic Scream

You gain the ability to release a deadly psychic scream. You may choose to use your attack action to target a number of creatures up to your Charisma modifier within 30 feet of your Host. A deadly sonic screech emanates from deep within.

Each of the targeted creatures needs to make a Constitution saving throw with a DC equal to 14 + your Charisma modifier. On a failed saving throw, the creature takes psychic damage equal to 10d4 + your Charisma modifier, and are stunned for 1 round (next round it won't be able to act). On a successful saving throw, the creature takes half as much damage and is not stunned. You may use this ability once per long rest.

This ability may be used an additional time at 5th tier, and a third time at 7th tier before needing to rest.
