Preserving Aurora

Auril the Frostmaiden has granted you the gift of preservation. Your skin now shimmers with a thin frost which you can use to invoke a protective light to shelter those close to you. You gain the benefits listed below;

• Increase your Wisdom score by 1, to a maximum of 20.
• When a creature (that can be blinded) you can see attacks a target other than you that is within 30 feet of you, you can use your reaction to impose disadvantage on the attack roll. Further attacks targeting any other ally within 15 feet of you until the start of your next turn are also at disadvantage. However, during this time, attacks have advantage to hit against you and you can't benefit from being invisible. You can use this reaction a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
• Using the above outside of combat gives you advantage on Intimidation checks. In addition when you talk with this feature active, your voice booms 3 times louder like in the thaumaturgy cantrip (this cannot trigger avalanches).
