@Vectner Take a look at the spell's last sentence.

@JeremyECrawford If Magic Missile doesn't affect creatures on the Ethereal Plane, what does the DMG mean by a "thing made of Magical Force"?

— Austin Lance (@takenbysubway) February 7, 2017

See wall of force for an example of something made of force that extends into the Ethereal Plane. #DnD https://t.co/rpJPaB9oox

@JeremyECrawford Cloak of Elvenkind grant the equivalent of the Ranger’s Hide in Plain Sight ability? Bypassed by Blindsight or Truesight?

— John Welker (@Saga_Welker) January 27, 2017

@Saga_Welker The cloak of elvenkind grants the benefits specified in its text—no more, no less.

@JeremyECrawford If an Oathbreaker Paladin is multiclassed, does the Control Undead Channel Divinity use character level or Paladin level?

— Ryan Muller (@Arcium_XIII) January 31, 2017

Control Undead refers to the paladin's level. The intent there is the character's level as a paladin. #DnD https://t.co/ekdCQAkhsY

@JeremyECrawford Dragonborn Sorcerer with Draconic Bloodline has two Draconic Ancestry traits. Can both be used for Elemental Affinity?

— Jeramie Brown (@jeramie_brown) January 21, 2017

Elemental Affinity refers to the draconic ancestry in the sorcerer, not Draconic Ancestry in the dragonborn. #DnD https://t.co/nEccITzKdT

— Jeremy Crawford (@JeremyECrawford) January 22, 2017

@DerynDraconisDragonborn traits use your dragonborn draconic ancestry
Sorcerer features use your draconic bloodline origin That's correct.

@JeremyECrawford can legendary resistances bypass portent dice? How does that interaction play out RAW and RAI?

— Karl Quigley (@Mister_Karlsky) January 31, 2017

Legendary Resistance is used in response to failing a saving throw. The trait doesn't care how that save was failed. #DnD https://t.co/TRVTUoykS3

— Jeremy Crawford (@JeremyECrawford) January 31, 2017

@Mister_Karlskyso our wiz sees the fail in his portent and then it passes anyway? Like a big aul scary legendary? It is, indeed, legendary.

@JeremyECrawford so how many spells can a caster actually cast in one round?

— Will White (@PlmbrWill) February 5, 2017

Is there a limit on the number of spells you can cast on a turn? See the Sage Advice compendium: https://t.co/dh02JRnEH8 #DnD https://t.co/MrsOqCM1QD

@JeremyECrawford If you Shove/Push a grappler grappling an ally, does it break the grapple (because of reach) at the cost of 1 attack? RAI?

— Marc Sharma (@LeMarcSharma) January 25, 2017

Leaving the reach of a grappler does, indeed, end the grapple, as stated in the third bullet of the grappled condition (PH, 290). #DnD https://t.co/sMpDlsHkMB
