@JeremyECrawford @mikemearls Does throwing a weapon benefit from dueling, archery, or neither?

— Alex Curnell (@ACurnell) September 2, 2017

The Archery and Dueling fighting styles are tied to ranged and melee weapons respectively, not to what you do with those weapons. #DnD https://t.co/zH8YBa3pQ3

So I.e. This is the difference between a true ranged weapon and thrown weapon than?

— Jon Gardiner (@Lothmegal) September 3, 2017

In the Player's Handbook's "Equipment" chapter, ranged weapons are on the ranged weapon lists & melee weapons are on the melee lists. #DnD https://t.co/lESeB8tVn5

A halfling fighter disengages can they run through the space of an enemy & attack using action surge?

Halfling Nimbleness lets you move through, but not stop in, the space of any creature that is of a size larger than yours. #DnD https://t.co/JkWuXZJLpp

— Jeremy Crawford (@JeremyECrawford) August 8, 2017

Follow-up question: Anyone can move thru nonhostile creature's space as difficult terrain. Is it normal terrain for a halfling?

— Keith Ammann (@geeniusatwrok) August 8, 2017

Halfling Nimbleness doesn't change the rule that other creatures' spaces are difficult terrain to you. #DnD https://t.co/5JEVCLHBk7

@JeremyECrawford does knowing primordial mean you can speak the other dialects? Storm Sorcerer not class specific from my reading in SCAG.

— Barry Zanone (@BarryZanone) August 13, 2017

If you know Primordial, you understand its dialects. For more on that topic, take a look at the "Languages" section in the PH (p. 123). #DnD https://t.co/Xbpu0t9JHz

Polymorph says “the creature can’t (…) benefit from any of its equipment.” Does that include magic items?Yes.

@JeremyECrawford Does having an ability score above 30 affect your modifier? Do you just consult the table on pg. 13 and determine the score

— Ernst Mikkelsen (@TheErnstinator) September 1, 2017

Ability scores go no higher than 30. For regular folk, they go no higher than 20. #DnD https://t.co/d4uKJPIZou

Is something like twin spelling polymorph OUTSIDE of the original intention of the twin spell mechanic? Or is that too far of an assumption?I kind of want to disallow twin-spelling spells that require concentration because it feels unfair. Am I totally off base here?No, that's reasonable

— Mike Mearls (@mikemearls) August 18, 2017

Twinned Spell intentionally works with concentration spells.

Situation: Area is under the Silence Spell. If a caster casts a spell and holds it in concenration outside of the Silenced area, and moves in to the area to release it during their same turn, would that require a reaction to release? Or part of the same action? All happening within 6 seconds.
You can end your concentration at any time. Doing so requires no action or reaction. #DnD https://t.co/rC4BJ21Rtq

Follow-up: does concentrating on a spell with a verbal casting component require the caster to chant for the duration of the concentration?

— Mavalanche (@aus_maverick) August 4, 2017

Components are required to cast a spell, not to concentrate on a spell. #DnD https://t.co/m0iJBPMqS6

My party is currently fighting another group of 3. the area the Barbarian is fighting inside of is currently under the effects of Silence. He’s low on health, and we’re having trouble healing him. Can our druid on his turn, cast the Verbal part of Cure Wounds outside of the silenced area, then move 20ft into the area and touch the Barbarian to heal him? Being as it’s the druids turn, would that require concentration, and if so, would it require him to expend a reaction to heal the Barbarian? If you want to cast a spell but wait to release the magic in response to a trigger/circumstance, that's what the Ready action is for. #DnD https://t.co/jMDf9FQVqo

— Jeremy Crawford (@JeremyECrawford) August 4, 2017

Right, I was wondering at what speed you had to cast a spell. For example, could you do V, wait a few seconds, do S, and touch the target?

— Keith (@Glytched) August 4, 2017

The Ready action doesn't let you divide up the casting of a spell. You cast it entirely, then hold it. #DnD https://t.co/btr78FpQXc

— Jeremy Crawford (@JeremyECrawford) August 4, 2017

What’s the rationale in having spellcasting work different from other actions with readying?The Cast a Spell action represents a subsystem. It is unlike the other actions that you can use with Ready.

— Jeremy Crawford (@JeremyECrawford) August 4, 2017

Yeah I saw- So ready allows to take an action and cast a spell then wait till a later initiative to see effects-even if not legal thn 2 castThat's correct.

— Jeremy Crawford (@JeremyECrawford) August 4, 2017

Hold? So you can then cast it outside of silence then have it go off in silenced area?That is, indeed, possible. See the final paragraph of the Ready action (PH, 193).

— Jeremy Crawford (@JeremyECrawford) August 4, 2017

So I was assuming that there was some reason, game balance or otherwise, why reading a spell involves casting it on your turnI was referring to the subsystem in chapter 10 of the PH. The Ready action must be different for spells simply because of casting times.

— Jeremy Crawford (@JeremyECrawford) August 4, 2017

The Ready action accounts for casting times and is meant to make readying a spell risky.
