The Echo Knight’s echo, does it count as a creature for the purpose of optional flanking rules and as a target to spells and attacks? If you're an Echo Knight in D&D, the magical echo you create is an image of yourself that occupies its space. It isn't a creature.
If this translucent, gray image were meant to be a creature, the rule would say so. #DnD https://t.co/ox6pxE8rY7

So how does a creature target the echo for an attack then? The rules say "Pick a target within your attack's range: a creature, an object, or a location." Would you have to rule that you are targeting the location of the echo? That seems kind of wonky

An Echo Knight's echo is an object. It's a translucent, gray image that occupies space; it isn't a creature; and it can be targeted. Object.
It's like you're targeting a moving painting or a hologram with substance. #DnD https://t.co/kmCZdEnNmu
