Illithid Mindforce (5e Feat)
From D&D Wiki
Prerequisites: You must be an illithid.
Your mind blast carries the awful force of your alien intelligence, and you have learned to properly shape it. You gain the following benefits:
- Increase your intelligence score by 1, to a maximum of 20
- Your Mind Blast becomes a 30-foot cone, the damage dice increase to d8s and you can add your Intelligence modifier to the damage dealt. Also, any creature that fails its saving throw against your Mind Blast is also stunned until the end of your next turn or until they take damage.
- When you use your Devour Brain racial trait to consume the brain of a creature with a Intelligence score of 13 or higher, you regain the ability to use your Mind Blast trait, as if you had taken a short or long rest.
