@JeremyECrawford I am sorry for such a long question, however I'd love your opinion on the matter. Sorry for this being a picture format but I have a question that I need your opinion on. How would you go on about explaining how someone can move 600 feet or 183 meters in 6 seconds (Single round)?A Barbarian with a base movement speed of 40 feet, plus10 feet from the feat mobile and someone tasted on him haste. That makes his movement speed 100 feet per turn. Now he goes the extra mile.Mufticlassin into a rouge for Cunning action making him able to dash as a bonus action as well as action. He then with haste has 3 dashes in a single turn making his movement speed 400 feet in a single round, but then he goes even further and mufticlasses into a fighter to gain action surge so he can have two additional dashes equaling 5 dashes on his base speed of 100 when all is active. I just end with telling the person he has a point of exhaustion once he does that because it pushes his limit beyond human capabilities. What say you about this? It’s one hack of a combo, he goes and dashes as a bonus action up to a person, stabs him with a knife using reckless attack to gain sneak attack because of advantage then dashes away and because of the mobile feat the target has no attack of opportunity, and is to slow to catch up to him so it goes in circles. There is a way around this and that is sentinel feat, or simply holding an action but a fight like this is insanely anime like. Sorry for the extremely long post, if you have read this then thank you even if you don’t have an answerjust state your opinion.
@matthewmercer yours as well. <3 pic.twitter.com/DBnmXo0OAj

@NikolaSuki @matthewmercer You get no more than 1 bonus action on your turn. And haste is a spell; its magic is meant to be extraordinary.

— Jeremy Crawford (@JeremyECrawford) December 7, 2016

@NikolaSuki @matthewmercerdoesnt action surge refresh bonus action as well? No.

— Jeremy Crawford (@JeremyECrawford) December 7, 2016

@NikolaSuki @matthewmercerI see. So the book refers to the possible bonus action as the one you already posses? That's correct.

@_Blackstormdoes ritual casting of a spell counts as casting that spell for all the effects related to the spell? Yes.

— Jeremy Crawford (@JeremyECrawford) January 31, 2017

@JeremyECrawford Are atwill spells meant to be cast without any v,s,m components, I ask because illithids use psyonics for theirs.

— Nathan Punnett (@VeiledDiscord) February 9, 2017

Being able to cast a spell at will doesn't remove components. A feature, like a mind flayer's Innate Spellcasting, can make exceptions. #DnD https://t.co/XoXa4qntcU

@P_Hataway @mattcolville For you, what is unclear about the spell?

— Jeremy Crawford (@JeremyECrawford) December 13, 2016

@P_Hatawaya few things actually: if the creature makes the save, does it avoid both the damage and the restraint? Yes.

— Jeremy Crawford (@JeremyECrawford) December 13, 2016

@JeremyECrawford in other words, does the spell save occur the turn the spell is cast, if there is a creature within its area of affect?

— Jaron P. Hataway (@P_Hataway) December 13, 2016

Does creating an area of effect on someone mean they entered it? See Sage Advice Compendium (look for "Evard"): https://t.co/WWVq6Y8bNj #DnD https://t.co/ww5tuueWmc

— Jeremy Crawford (@JeremyECrawford) December 13, 2016

@P_Hataway lastly, I’m assuming that a creature would need to make the Dex save for every turn it starts in the affected area. Yes.

@JeremyECrawford @ChrisPerkinsDnDIs there a way for a Monk (,or any class for that matter,) to have an animal companion? *sans multiclassing, there a way for a class other than ranger, druid or wizard to have an animal partner?

— Mathew Michalak (@Trogaf) February 2, 2017

Animal Companion—use a spell/feature that gives you one (player controlled), or get one to join you via skills/roleplay (DM purview) #DnD https://t.co/DE2kx3GcCh

— Jeremy Crawford (@JeremyECrawford) February 2, 2017

@armando_doval @Trogafby DM discretion I think he means letting player invest time, money and Animal Handling proficiency to tame a beast Precisely.

@JeremyECrawford If you critically hit with the attack part of Green Flame Blade, and are greater than level 5, do you roll extra dmg against the 2nd target?

— Eric Green (@quadhund) April 17, 2017

The splash damage of green-flame blade isn't affected by the attack critting. Think of the attack as process X & the splash damage as Y #DnD https://t.co/ptNK60i46A

— Jeremy Crawford (@JeremyECrawford) April 17, 2017

@JeremyECrawford Do you play mutually blind combatants both get disadvantage? Or does advantage and disadvantage cancel out as Raw implies?

— Klaude Thomas (@vonklaude) May 27, 2017

Advantage and disadvantage cancel each other. That's fundamental to how they work. #DnD https://t.co/QHbyxuUIyV

— Jeremy Crawford (@JeremyECrawford) May 27, 2017

@JeremyECrawford I was wondering what should a player do if they want to tackle a character? Or at the very least barrel into a foe for dmg?

— Haka (@Hakasami) April 2, 2017

Tackling someone? Use one of these options, depending on your goal:

Unarmed strike
Grappling
Shoving

See Player's Handbook, p. 195. #DnD https://t.co/VdGxV1D1Gc
