@JeremyECrawford @mikemearls @ChrisPerkinsDnD Spellcasting focus. Can a bard use their voice for this? Or a dance?

— Matthew Roderick (@tazyMatt) September 11, 2016

A spellcasting focus subs for a material component. Your voice is a verbal component. Dance would be somatic. #DnD https://t.co/lvmvyPiALw

That doesn’t make sense, the voice is an instrument. The music definition of instrument is an object or device for producing musical sounds. The rule on a bard's spellcasting focus (PH, 53) refers to the sorts of musical instruments that appear in the PH equipment chapter.

@PhilippMordashe MM says that beholder zombie’s eye rays are magical. Does that mean that you can use Dispel Magic to end paralyzing ray effect? yes

— (((Mike Mearls))) (@mikemearls) October 24, 2016

@PhilippMordashe great to know! But what is the target DC to end the effect? For spells it’s 10+spell level, but paralyzing ray doesnt have level I'd use 10 + creature CR

— (((Mike Mearls))) (@mikemearls) October 24, 2016

@mikemearls @JeremyECrawford would it also be viable to use the DC for the effect itself?

— Emmanuel Acosta (@EmmanuelBAcosta) December 21, 2016

@mikemearls @EmmanuelBAcostathat’s a good approach Dispel magic has no effect on something that isn't a spell. But if a DM rules otherwise, this works.

— Jeremy Crawford (@JeremyECrawford) December 21, 2016

@EmmanuelBAcosta @mikemearlshmm… so the “magical effect” described on the spell HAS to come from another spell? That's correct.

— Jeremy Crawford (@JeremyECrawford) December 21, 2016

@EmmanuelBAcosta @mikemearls No problem!

@JeremyECrawford Just my monthly ask about whether Careful Spell can be used with Cloudkill?

— Eric Green (@quadhund) March 9, 2017

Careful Spell is used the turn you cast a spell and is intended to affect saving throws made that turn. #DnD https://t.co/QK1QurR4FO

— Jeremy Crawford (@JeremyECrawford) March 10, 2017

@aweeks007so careful fireball should mean your protected targets take half damage? *cough* #wafflecrew That's correct.

— Jeremy Crawford (@JeremyECrawford) March 10, 2017

This has got to be the worst RAI ruling I’ve ever seen. Careful spell is now compatible with 5 sorcerer spells that don’t do damage. Careful Spell works with fireball, lightning bolt, and many other spells.

@Sands_Tavares @mikemearls @ChrisPerkinsDnDThough it’s easy enough to deduce, why not include proficency bonus on monsters’ stat blocks? It's rarely relevant when you're running a monster.

— Jeremy Crawford (@JeremyECrawford) March 11, 2017

@CinarDemir @Sands_Tavares @mikemearls @ChrisPerkinsDnD isn’t it v relevant for NPCs at the end of MM? Like Guards, Knight etc An NPC's proficiency bonus is accounted for in its stat block.

— Jeremy Crawford (@JeremyECrawford) March 18, 2017

@CinarDemir @Sands_Tavaresyes it is, I meant it might be easier if it had a string on its own like “AC 14, Speed 30, Prof +2.” How would you use that number on a regular basis?

— Jeremy Crawford (@JeremyECrawford) March 18, 2017

@Lexar131Can a warlock 5th level cast Eldritch Blast aim one beam at a target, move 20 feet then aim the 2nd beem at a different target? believe yes #WOTCstaff

— (((Mike Mearls))) (@mikemearls) November 12, 2016

@Lexar131 @mikemearlsso it follows same rules as with multiattack with weapons? you can break it with movement. Same applies to scorching ray? "If.. an action that includes more than one
weapon attack, you can break up your movement…"Specifically WEAPON p190

— Brail (@BrailSays) December 11, 2016

@BrailSays @Lexar131 @mikemearls No general rule allows you to move between the attacks of a spell.

@JeremyECrawford Are spells like Cone of Cold and Lightning Bolt “spells that target only you” in regards to Find Steed’s boon to the steed?

— .|||. Matt (@KingOdysseus) January 26, 2016

A spell that targets only you is one that has a range of self and no area-of-effect parenthetical. #DnD https://t.co/iLcuOuFJLx

— Jeremy Crawford (@JeremyECrawford) January 29, 2016

@Hashike so, excluding AoE spells, the spell range must be strictly “self”, meaning a spell unable to target anyone else?
Regards That's correct.

— Jeremy Crawford (@JeremyECrawford) February 8, 2017

For the purposes of the find steed spell, a spell like cure wounds that you cast on yourself—targeting only you—also affects the steed. #DnD https://t.co/m27UbswWXw

— Jeremy Crawford (@JeremyECrawford) May 15, 2017

Would this also apply to the boost to Dex saves provided by the shield master feat?

“Spell or harmful effect that target only you.” That tweet of mine was only in reference to the find steed spell.
