@JeremyECrawford @matthewmercer question about the echo knight, can you switch places with the echo if you are using the echo avatar feature?

The intent is that you can't do anything with the Echo Knight's echo while using Echo Avatar, other than scout with it. The text stating that intent is mysteriously missing from the book. We'll fix it in a future printing! Sorry about the confusion. #DnD https://t.co/AZXJGZUYLw

RAI, with the Echo Knight, is it supposed to be susceptible to Fireball? How about Shatter? @matthewmercer @JeremyECrawford
I know how I am currently ruling for my game, but I wondered.

The fireball spell in D&D forces creatures to make a saving throw. The Echo Knight's echo is intentionally not a creature, so it doesn't make the save.

The shatter spell affects creatures and nonmagical objects. The echo is intentionally neither of those things. #DnD https://t.co/3jlUa7QAQt

@JeremyECrawford When casting Temporal Shunt at 6+, if one of the additional creatures is concentrating on a spell, are they able to maintain concentration through time, or does the lapse cause it to break? #EGtW #DND

The temporal shunt spell in D&D has no effect on a target's concentration.

The rule on concentration (PH, 203) lists what breaks concentration. An effect doesn't break concentration unless it's on that list, a rule makes an explicit exception, or the DM rules otherwise. #DnD https://t.co/apS451VZxg

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
