Martial Echo

1st-level Infinite

At 1st level, you can use a bonus action to magically manifest an echo of yourself in an unoccupied space you can see within 15 feet of you. This echo is a magical, translucent, gray image of you that lasts until it is destroyed, until you dismiss it as a bonus action, until you manifest another echo, or until you're incapacitated.

If your echo has to make a saving throw, it uses your saving throw bonus for the roll. It is the same size as you, and it occupies its space and is considered a creature for effects of targeting. On your turn, you can mentally command the echo to move up to 30 feet in any direction (no action required, at the cost of 5 of your movement). 

You may have a number of echoes active equal to your proficiency bonus, but once an echo is destroyed it remains destroyed until a long rest.
