Frenzy of the Hound

While raging, you can choose a target, within 160 feet. The target must make a DC 21 Con save or be under the effects of a frighten for 1d10 rounds of combat.

To them you have a terrifying aura around you, resembling fiery skulls of Hellhounds. These beasts add a +1d8  to your melee attacks as the hound lashes out and bite the target. (You can only apply 1 hound bite of 1d8, but the illusion depicts three hounds.).

Nobody else can see the aura unless they cast detect magic. If the target succeeds the save, nothing happens. You can only use this three times per long rest.
