@JeremyECrawford Please can you confirm an AoE spell cast into an area with PC's and creatures will effect everyone not just enemies?

— Mike Verling (@mverling) February 1, 2016

An AoE spell like fireball targets everyone in its area (says "each creature"). Other spells are selective. #DnD https://t.co/ch98U6dycx

“5 foot-radius sphere centered on a point within range” which one is correct? #dnd @ChrisPerkinsDnD @mikemearls pic.twitter.com/qe6JxXQlc2

The circle on the left has a 5-foot radius. The circle on the right does not. https://t.co/uegJ8E2LOg

@DM_Screen @DropTheDie @DnDDomain @ChrisPerkinsDnD I’d use the red one – blue one is pushing radius a bit further out to snap to grid

@mikemearls @DnDDomain @ChrisPerkinsDnD Thanks for the insight, Mike. Most people seem to agree. These will help: pic.twitter.com/brH6BYXclk

@DropTheDie @xenon_ST @ChrisPerkinsDnD yup – that’s the intent

— Mike Mearls (@mikemearls) February 28, 2016

@ChrisPerkinsDnD @DropTheDie @JeremyECrawford The question then becomes how much of a 5ft grid square has to be covered for it be affected?

— Mavalanche (@aus_maverick) February 27, 2016

If an area of effect is circular and covers at least half a square, it affects the square (see DMG, 251). #DnD https://t.co/Qilytnphqk

@JeremyECrawford @mikemearls Druid Wild Shape: 1)Can only be used to take the form of "beast" type? 2)Can be used to become a Swarm of Bats?

— Draconis (@DerynDraconis) January 18, 2016

Wild Shape lets you transform into a single beast. A swarm is a collection of beasts, not one. #DnD https://t.co/PLy45nvdVp

@JeremyECrawford @DerynDraconis @mikemearls what if you got a bunch of druids together and all wild shaped into the same type of creature?

— Ken Livingston (@undrhil) January 18, 2016

The druids could then turn into a cuddle puddle composed of cute animals. #DnD https://t.co/bmuW8w7dAk

@JeremyECrawford Counterspell & Dispel Magic: when I cast them, I know or I don’t know the spell’s level of the opponent spellcaster? Thanks

— Draconis (@DerynDraconis) February 29, 2016

My house rule: you ID a spell being cast (default lvl.) if it’s on your spell list and you observe the casting. #DnD https://t.co/fxd24pHnBE

— Jeremy Crawford (@JeremyECrawford) February 29, 2016

@ZarconistPreist @DerynDraconisWait so its not normally known what the level of the spell is? I thought that was the default. You know the spell’s default level, as opposed to a higher level that it might be cast at.

@JeremyECrawford How does savage attack (and brutal critical) differ between greataxe and greatsword? 2d12 and 4d6 or 3d6?

— Jeromy D'Amico (@Herodragon33) January 14, 2016

Savage Attacks (half-orc) and Brutal Critical (barbarian) add 1 die. Greataxe: +1d12. Greatsword: +1d6. #DnD https://t.co/jfYm6bg0Bn

@JeremyECrawford Is Monk's Diamond Soul feature intended to grant proficiency in Death saves?

— Mike Everard (@TheGingrel) January 15, 2016

The monk's Diamond Soul feature grants proficiency in all saves. A death saving throw is a save, so yes. #DnD https://t.co/Q7bVcyOXwg

@JeremyECrawford True strike followed by witch bolt what happens mechanically?

— Anonymous Mouse (@DoomsdayDog) January 16, 2016

Your concentration on a spell is broken the instant you cast another spell that requires concentration. #DnD https://t.co/YVOFhCMJ3J
