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

@JeremyECrawford is the Explorer's Guide to Wildemount considered official D&D material? Certainly Mr. Mercer is an expert weaver of tales and is very familiar with the mechanics but are these subclasses, items, and spells tested? Has it gone through what other books go through?

EXPLORER'S GUIDE TO WILDEMOUNT is a delightful introduction to the world of @CriticalRole. Like every D&D book, its rules have been tested by players, developed by the D&D team, and vetted by me. There are juicy subclasses, spells, magic items, and monsters awaiting you! #DnD https://t.co/by9s5P8tK9

@JeremyECrawford @matthewmercer @Dan_Dillon_1 Is the Pride Silk Outfit actually armor? As in you need Light Armor Proficiency to wear it? Or would anyone (i.e. Sorcerers and Wizards) be able to and still benefit from the improved AC without any drawbacks?

In Explorer's Guide to Wildemount, a pride silk outfit is not armor. It's clothing that gives you an AC calculation if you're not wearing armor. #DnD https://t.co/zG5NqmxoM9

So does it stack with Mage Armor?

— love, steveo (@ravenwing263) April 6, 2020

In D&D, Armor Class calculations don't stack.

For example, if one feature lets you calculate your AC as 11 + your Dexterity modifier and another lets you calculate it as 13 + your Dexterity modifier, you have to pick which one to use. You don't get both. #DnD https://t.co/mdg9q71Ag4

Hey @Dan_Dillon_1 & @JeremyECrawford, just checking:

Is the Echo Knight's echo constrained by the Echo Knight's available movement modes, or does "30 feet in any direction" implicitly include the Z axis?

I *assume* they are constrained?

— Harbinger of Doom (@BrandesStoddard) March 24, 2020

Includes Z axis.

It does occupy physical space and needs a clear path to move.

— Dan Dillon 👥 (@Dan_Dillon_1) March 24, 2020

The Echo Knight's echo has no speed and no movement modes. You can move it up to 30 feet in any direction—horizontally, vertically, or diagonally. #DnD https://t.co/pKvuVNEnTu

@matthewmercer @JeremyECrawford For Echo Knight's opportunity attack it says "When a creature that you can see within 5 feet of your echo moves at least 5 feet away from it," if I've got a weapon with reach, would that mean I can do this attack from 10ft away?

So I’m fixing to be the world’s first Tortle Blood Hunter and I’m leaning on the Order of the Mutant. Q: What happens if I feed a mutagen to a ally or foe? Like via a dart or coated on a blade? Is it all possible for them to roll to embrace or avoid the effects? From a balance standpoint, anyone who’s body isn’t tuned to the mutagen (anyone but you) gain no effects from it. Your DM can choose otherwise, but that is the intended design.
