@JeremyECrawford PHB p152 Lock: "creature proficient with thieves tools can pick this lock". It means I cannot use a tool if not proficient?

— Draconis (@DerynDraconis) February 17, 2016

That is a rule for the generic lock (PH, 152), not for tools in general or even all locks. #DnD https://t.co/9mueWht8Dm

@JeremyECrawford Ok, it's lock specific rule. So, even though I never studied music, I can play musical instrument without being proficient?

— Draconis (@DerynDraconis) February 18, 2016

The DM decides if your music is pleasing & proficiency with an instrument lets you use your prof. bonus w/ it. #DnD https://t.co/OiHrZAwbDf

@JeremyECrawford @ChrisPerkinsDnD Is there a difference between attunement and identify?

— D&DDungeonMistress (@DnD5eMistress) August 16, 2016

Identify is faster than the attunement process, and the spell tells you more. #DnD https://t.co/XcaRZHA8Cd

@JeremyECrawford If you have levels of Monk 1/Bladesinger 4, do you stack the Intelligence AC bonus on top of the normal Monk Dex+Wis?

— Christopher Goto (@Umbralatro) June 28, 2016

A bonus applies as long as you don't already have a bonus from the same feature/effect. #DnD https://t.co/G1cgx0yZwh

@PerestaMASo does that mean no? Just like when you try to combine monk with mage armor? That means yes. A bonus goes on top of an AC calculation.

— Jeremy Crawford (@JeremyECrawford) July 27, 2016

@PerestaMAbut don’t both set your ac at a value and not “give a bonus?” Bladesong explicitly gives you a bonus.

@JeremyECrawford For making magic item, Vorpal Sword says "any sword that deals slashing". I take it that excludes other slashing? axe/whip?

— Joseph Bridgewater (@JOSEPH91304707) October 26, 2016

"Any sword that deals slashing" does, indeed, refer only to swords. #DnD https://t.co/CHySt1sQOg

@JeremyECrawford Fighter hidden with Extra Attacks and a bow: if attack a target he gets advantage on attack with all 4 arrows, or only 1st?

— Draconis (@DerynDraconis) October 4, 2016

If you're hidden and you attack, you give away your position when your first attack hits or misses (see PH, 194–5). #DnD https://t.co/GnVTc41szI

— Jeremy Crawford (@JeremyECrawford) October 4, 2016

@JeremyECrawford Does this apply to spells like Scorching Ray as well? Or you'll have advantage on all 3 rays?

— Philipp Mordashev (@PhilippMordashe) October 6, 2016

If a rule applies to attacks and makes no exceptions for different types of attacks (weapon, spell, etc.), it applies to all attacks. #DnD https://t.co/L209v70v1Z

— Jeremy Crawford (@JeremyECrawford) October 6, 2016

Unless the rules explicitly expand, narrow, or completely redefine a word, that word retains the meaning it has in idiomatic English. #DnD

@JeremyECrawford If a spell cast from a spell scroll is counterspelled, does the scroll lose its magic as if the spell was cast?

— Marc Sharma (@LeMarcSharma) October 14, 2016

When successful, counterspell foils a spell that is cast. The casting isn't undone. The spell fails and is wasted. #DnD https://t.co/3X228KdMOf

With Brutal Critical and a Greatsword do you get to reroll only 1d6 or both 2d6?

The barbarian’s Brutal Critical gives the number of dice the feature specifies (greatsword gets 1 die to start). https://t.co/h1AtbMnzx0
