once you finish a campaign, your dungeon master can grant you traits of the Ashen rider which are:

Aura of Silence. When a enemy creature starts its turn within 30 feet of you, you can force that creature to make a DC 15 Wisdom saving throw if you can see it. On a failed save, that enemy creature can’t speak and is deafened for one turn.

Mount. If you aren’t mounted, you can use a bonus action to magically teleport onto the creature serving as your mount, provided you and your mount are on the same plane of existence. When you teleport, you appear astride the mount along with any equipment you are wearing or carrying. While mounted and not incapacitated you can’t be surprised, and both you and your mount have advantage on Dexterity saving throws. If you are reduced to 0 hit points while riding your mount, your mount is reduced to 0 hit points as well.

note: you need to have acquired the feat called, (E.N.H.) Rider Evolution, in order to take this feat.
