You can shield yourself and others with telekinetic force. As a Bonus Action, you can choose creatures, including yourself, within 30 feet of yourself, up to a number of creatures equal to your Intelligence modifier (minimum of one creature). Each of the chosen creatures has Half Cover for 1 minute or until you have the Incapacitated condition.
Once you use this feature, you can't do so again until you finish a Long Rest unless you expend a Psionic Energy Die (no action required) to restore your use of it.
