@TimDeCapioCan surprised player with high initiative use a reaction after ‘his turn’ is done in surprise round? Yes.

@JeremyECrawford Wil you be able to get OA with the sentinel feat on a flying creature with the "flyby" trait?

— Bernt Bergum (@Maraxion) October 17, 2016

A Flyby creature doesn't provoke an opportunity attack when it flies out of a foe's reach. Nothing in the Sentinel feat counters that. #DnD https://t.co/1p8AQBBqvu

@JeremyECrawford @Maraxion on that note, would a pole arm master get an OA as the flyby enters range?

— Dreadwolf (@HVargavinter) October 17, 2016

Flyby protects you when you fly out of a foe's reach, not when you fly into it. #DnD https://t.co/cBMv5Yh8Kj

@JeremyECrawford Can you hide from a creature with blindsight: behind a pillar? In a barrel? Around a corner? Behind a wall? Camouflaged?

— Poljack (@Poljack) June 17, 2016

You can't hide from a creature if you're in its blindsight radius, unless magic cloaks your presence entirely. #DnD https://t.co/9lEjumLFYt

@JeremyECrawford Can a fighter use rally on himself? It uses the same language noted in spells targeting yourself on page 204.

— Colin Smith (@NerfPyroPlz) September 28, 2016

The Rally feature targets one of your companions—an ally of yours. #DnD https://t.co/zC7Tf6Q5AV

— Jeremy Crawford (@JeremyECrawford) October 26, 2016

@NerfPyroPlzAre you sure? Same language in inspiring leader to a different effect. Isn’t ‘a creature you can see and hear’ the target? The pertinent words in Rally are "a friendly creature."

— Jeremy Crawford (@JeremyECrawford) October 28, 2016

@NerfPyroPlzThanks for the response, but I’m still confused. Inspiring leader also says “friendly creatures” and allows self targeting. Yes, Inspiring Leader says you can target yourself.

— Jeremy Crawford (@JeremyECrawford) October 28, 2016

@JeremyECrawford ofc, but if target words are "friendly creature" and IL lets you target yourself, doesn't it follow that rally can too?

— Colin Smith (@NerfPyroPlz) October 28, 2016

An exception (a spell/feat/class feature/etc.) has no bearing on the interpretation of another. The exceptional builds on the general. #DnD https://t.co/KPly0cuK9s

— Jeremy Crawford (@JeremyECrawford) October 29, 2016

@NerfPyroPlzIt absolutely must when there’s no non-spellcasting target rules. RE: on 204 it says “creature” can target yourself. cont. Rally and Inspiring Leader contain the necessary information for their targeting.

— Jeremy Crawford (@JeremyECrawford) October 29, 2016

@NerfPyroPlzIf self contained, why create an exception to a rule 1 sentence earlier in inspiring leader? At very least, bad editing. Inspiring Leader creates an exception to the meaning of the word "companions" because that's the design intent for the feat.

— Jeremy Crawford (@JeremyECrawford) October 29, 2016

@NerfPyroPlzWhy? If it’s self contained, say “everyone” instead of “not you, but you”. Makes ‘companion’ look like 4e (ally = you also) The exception is made precisely because the game doesn't normally depart from the English meaning of "companions."

@mikemearls @Asmogorgon @ChrisPerkinsDnD @JeremyECrawford @MikeMercer Sorry – when do you use Passive Perception instead of rolls?

— Bryce Walton (@BryceWalton) October 28, 2016

A DM uses passive Perception when you might notice something but aren't actively searching. If you search, you make a check. #DnD https://t.co/9QhN7mM007

@Scottbad88 You have my blessing to do whatever you enjoy. It's your DM's call.

— Jeremy Crawford (@JeremyECrawford) October 24, 2016

@Scottbad88so I have your blessing to play as a TREX with long arms… because that is ridiculous! If your DM wants to house rule that you can play a tyrannosaurus rex, go for it! That brave DM must deal with the consequences.

— Jeremy Crawford (@JeremyECrawford) October 24, 2016

@Scottbad88a level 1 monk, does it get two attacks (each hand or leg) and then a bonus attack from martial arts? I'm curious, why do you think the monk would get two attacks before the bonus attack?

— Jeremy Crawford (@JeremyECrawford) November 7, 2016

@JeremyECrawford just like a ranger or fighter with two light single handed weapons get 2 attack per attack action

— Scott Badalamenti (@Scottbad88) November 7, 2016

The rule on two-weapon fighting requires a bonus action (see PH, 195). It doesn't add attacks to the Attack action. #DnD https://t.co/QgBke7I12T

@cisko@JeremyECrawford Talking spellcasting today, I guess! Can a wizard use a magic wand (e.g. wand of Magic Missile) as her arcane focus? Yes.
