Upon reaching 18th level as an Echo Knight Fighter you gain the ability Legion of One.
You can use a bonus action to create two echoes with your Manifest Echo feature, and these echoes can coexist. If you try to create a third echo, the previous two echoes are destroyed. Anything you can do from one echo’s position can be done from the other’s instead.
Can you move both echos 30′ each or is it just a shared 30′ of movement between the two?
