@JeremyECrawford I'd love to hear the background on why 1s and 20s aren't auto-success/fail for ability checks. Would you be willing to share?

— Callum Grier (@CalGrier) April 10, 2018

In the realm of ability checks, there are meant to be tasks that only an expert can accomplish and other tasks that an expert would never reasonably fail. For such checks, we don't give a 1 or 20 on the d20 any special meaning because we don't want to subvert that intent. #DnD https://t.co/no59E2F2XA

@ToddKenreck @mikemearls @JeremyECrawford Sword Coast Guide details sun & moon elves but @DnDBeyond lacks these races, even with legendary bundle. Any plans to include them in the future?

— Eli Dalton (@KSDrae) April 22, 2018

As described in Sword Coast Adventurer's Guide, sun and moon elves have the racial traits of high elves from the Player's Handbook. You can already play either of those races by choosing high elf.

Sun elves and moon elves are in the "Player's Handbook." They're high elves. #DnD https://t.co/G8mJ5WoH8K

@JeremyECrawford Can disintegrate disintegrate a creature that is already at 0 hit points?

— Jackson Bockus Ban Nazis, Jack (@JacksonBockus) April 14, 2018

The disintegrate spell has a loophole in it. RAI: The spell disintegrates you whether it deals damage to you when you're at 0 hit points or it reduces you to 0 hit points. RAW: You aren't disintegrated if the spell deals damage to you when you're already at 0 hit points. #DnD https://t.co/MW1pw8KbfX

Will that be corrected in future printings?

— Daniel Stanton (@DanielStanton98) April 14, 2018

Whenever we discover an error in our books, we put the correction into the reprint queue. We make corrections from that queue—usually a batch of them—when the printer's schedule allows it. After that, we publish an errata document describing the changes. #DnD https://t.co/yCt7uTbDml

@JeremyECrawford Spell Thief feature lets you force a saving throw with spellcasting ability mod. Is it considered to be the same kind of ST as the modifier? For example, if the creature use int mod for spells,Is it a Int save? I ask because of proficiency bonus.

— Ironforged (@TrueIronforged) November 22, 2017

If you make a saving throw using a particular ability modifier, you're making a saving throw using that modifier's ability. For example, an Intelligence saving throw is a save that uses your Intelligence modifier. See "Saving Throws" (PH, 179). #DnD https://t.co/TM74CtVyPu

— Jeremy Crawford (@JeremyECrawford) November 22, 2017

Okay, so a int save uses int modifier and any save using the int modifier is an int save.Yes.

@JeremyECrawford can the sun blade be used to cut and/or incapacitate enemies?

— Runa Snow (@Runa_Tiger) April 15, 2018

When the blade of the sun blade is present, the magic item functions as a longsword. It can do the things longswords can do. #DnD https://t.co/IdhkRonWTX

@JeremyECrawford One player wants to play an Aasimar (from Volo's Guide to Monsters) Sorcerer with the Divine Soul origin (from Xanathar). Seems like a natural combo, but breaks the PHB+1 rule. The inverse (Tiefling with evil Divine soul) would be fine. Should I allow it?

— David Parkinson (@drdrparky) March 13, 2018

The PH + 1 rule applies to Adventurers League only. In your home game, allow whatever you like! #DnD https://t.co/kPNDn5NmGv
