@ChrisPerkinsDnD If I add Luring Song (see: Harpy) to a custom monster, how much CR adjustment do you recommend? It's not in DMG 280-281.

I wouldn't make any adjustment to the creature's challenge rating. #WOTCstaff https://t.co/fIi89L3jTA

@ChrisPerkinsDnD @JeremyECrawford @mikemearls How do you Insight rolls? Lie detector or body language reader?Hidden or open?Your/their roll?

— Marc Sharma (@LeMarcSharma) March 8, 2017

I let players roll, use it to sense lies, get a general sense of creature's mood/state of mind. #wotcstaff https://t.co/wVQ9S3f67b

@JeremyECrawford @mikemearls @ChrisPerkinsDnD I.e. poly'd into a T-Rex. Do you see your friends still…or nice bite-sized morsels?

Hey @SUEtheTrex can I get your insight into this question as a tyrannosaurus Dungeon Master? #wotcstaff https://t.co/u1ZZXD6v2L

@ChrisPerkinsDnD Question; is the damage from an Elemental considered magical, or is it natural? I always saw them as incarnations of nature

— Mike Grenier (@EternalRavager) February 22, 2017

If a creature's attacks are magical, its stat block says as much. (For example, see the balor demon.) #WOTCstaff https://t.co/CVY493DjPa

@ChrisPerkinsDnD @JeremyECrawford considering you created the revenant does the DnD setting allow for a vampire PC that is not evil?

— shnelle hope (@shnellehope) March 2, 2017

D&D can accommodate just about anything, including non-evil (and preferably non-sparkly) vampire characters. #WOTCstaff https://t.co/ZV7ZynvfJB

@ChrisPerkinsDnD assuming a planer portal is fixed to a location, do you think birds could develop migratory patterns that cross planes?

— Lindsay Scammell (@Scammell_) February 15, 2017

That's a very cool idea, so let's say YES! #WOTCstaff https://t.co/3u98iBt3ll

@ChrisPerkinsDnD Should I actively try and pull punches to avoid a TPK? How do you approach that when DMing?

— Blake (@blake_denzer) March 10, 2017

That's really your call. Intelligent foes might choose not to kill characters and instead knock them unconscious. #WOTCstaff https://t.co/kVtZ6Qtwqf

@mikemearls if you were to challenge a devil to a fiddle contest, what would his Performance bonus be?

— Wait…What? (@davoerlo) March 9, 2017

Congrats to today's winner of D&D. Folk lore suggests devils have an affinity for fiddles, so I'd say proficiency + Dex #wotcstaff https://t.co/h6hMHFNpEq
