@andrewphillipc1 @JeremyECrawford @ChrisPerkinsDnD @Wizards_DnD @NerdarchyCan you cast enlarge/reduce on a sphere of annihilation? (DMG201) I would allow that – spell works on objects

@JeremyECrawford If you have War Caster, can you cast as a reaction on OAs triggered by the Sentinel feat?

— Daniel Gray (@filmadept) March 15, 2016

The attack granted by the third benefit of the Sentinel feat isn't an opportunity attack. #DnD https://t.co/XT5UPjjMQS

@JeremyECrawford Question about glaives and halberds: Can the bonus attack from Polearm Master be taken at 10 feet reach as well?

— NinjaKirby1322 (@ninjakirby1322) March 25, 2016

The bonus attack of Polearm Master can use the weapon's reach. The feat would tell you if it couldn't. #DnD https://t.co/xwQpmNgUBW

@JeremyECrawford Do air/fire/water elementals suffer any penalties for fighting or using skills in a medium or smaller space?

— Miksar (@Miksar1) March 22, 2016

An air/fire/water elemental ignores the movement part of the squeezing rule (PH, 192) in a 1+ inch space. #DnD https://t.co/fh6q3H3hXX

— Jeremy Crawford (@JeremyECrawford) March 22, 2016

@Miksar1 So the squeezing clause in them only applies to movement and not fighting? That's correct.

@JeremyECrawford Darkvision specifies that you see dim as bright in 60', then says you see dark as dim. Is that also 60', or unlimited?

— MelTorefas (@MelTorefas) April 1, 2016

All of darkvision's benefits are limited by its radius. #DnD https://t.co/zkmumFtzKl

@MtS_Designer @JeremyECrawfordWhy ring of warmth is only uncommon, while the ring of resistance (cold) is Rare and do less stuff? oversight? oversight – resistance was probably added and overlooked in design

@ChrisPerkinsDnD Do you ever miss being a PC at all?

— John Wehr (@Ozai75) March 23, 2016

Yes, but @JeremyECrawford runs a game that I'll be playing in soon, so that should fill the void nicely. https://t.co/IKfZHQUPpY

@LeonardoRaele @ChrisPerkinsDnD @Ozai75What character will you be playing, Chris? He plans to play a halfling rogue.

Dear Mr @ChrisPerkinsDnD. What class is your preferred weapon of choice when you play (not dm) dungeons and dragons??? Big fan by the way

— Batcat (@Batcat13) March 23, 2016

A wizard is always fun. I like to play rogues and rangers as well. https://t.co/lO0Bp6MH5K

@TheFakeHaragos @ChrisPerkinsDnDDoes fog cloud block sunlight? If not does any spell? #AskingforaVampireFriend only darkness effects would block it
