Banner of the Resolute

This well fashioned banner can be attached to a staff or worn as a cape. You can use an action to raise the banner and give an inspiring speech. Allies within 30 feet who can hear you gain temporary hit points equal to your level + your Charisma modifier (minimum of +1). Allies cannot benefit again from this effect until after a short or long rest. 

In addition allies under the effect of the banner are immune to the frightened condition for 10 minutes. If an ally has to the frightened condition, it is removed.
