Starting at 7th level, you can temporarily transfer your consciousness to your echo. As an action, you can see through your echo's eyes and hear through its ears. During this time, you are deafened and blinded. You can sustain this effect for up to 10 minutes, and you can end it at any time (requires no action). While your echo is being used in this way, it can be up to 1,000 feet away from you without being destroyed.
At 3rd level, you can heighten your echo's fury. Whenever you take the Attack action, you can make one additional melee attack from the echo's position.
You can use this feature a number of times equal to your Constitution modifier (a minimum of once). You regain all expended uses when you finish a long rest.
