@MerricB Doesn’t casting a spell with a longer casting time require concentration? The reference on PHB 202 even mentions rituals. That's correct!

Does Greyhawk exist in Dungeons&Dragons 5 edition? How does the history of Tenser, Mordenkainen and Bigby (& their related spells) relate to #ForgottenRealms?

Greyhawk does, indeed, exist in the D&D multiverse, which is talked about in the introduction of the PH (p. 5–6) and in the DMG. #DnD https://t.co/ttbeO2TvaY

@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 If cutting words is used on an AoE effect like fireball, does it reduce the damage the group would take or only the bard?

— Todd Sampson (@fmacanadaguy) September 20, 2016

An AoE like fireball has a single damage roll. If you use Cutting Words on such a roll, the damage reduction applies to all targets. #DnD https://t.co/RnpxSNogrH

If mage armor doesn't count as armor then would a monk get ac 13+Dex+Was? #WOTCstaff @ChrisPerkinsDnD @JeremyECrawford

Does mage armor work with Unarmored Defense? The Sage Advice Compendium has the answer: https://t.co/dh02JRnEH8 #DnD https://t.co/NT0xIYmcHn

@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 When the monster Manual list a specific save do you add that to the monster's stat bonus or is that the total save modifier

— kent dyer (@saxononyx) November 15, 2016

Take a look at the Monster Manual introduction, specifically the section on saving throws (p. 8). In a stat block, save bonus = total. #DnD https://t.co/SXaO7XYHQG
