@IHitItWithMyAxeHI Jeremy? Does uncanny dodge work automatically on every seen attack the rogue gets hit with? Magic too? Yep! Uncanny Dodge works against attacks of all sorts, even spell attacks.

@nirvanstryder @IHitItWithMyAxedoes it work against each successful attack made by opponent who has multiple attacks or is it one attack A use of Uncanny Dodge works against one attack. Like Defensive Duelist, it expends your reaction.

@imnotasnowflakeElf trance: does it affect long rest for Elves? How? Just less sleep? A long rest is 8 hours for an elf, but the elf can spend much of it on watch and doing light activity, while others sleep.

@GrogSDWhy does it say 4hr = “you gain same benefit that a human does from 8hr” when a rest is 8 hr of sleep.
A long rest can be a mix of sleep and light activity.

@TinyConstructWith cantrips, does a MC caster use their character or class level for determining damage? A multiclass character uses character level to determine the damage of a cantrip.

@tragicjones @mikemearlsIs the bard’s Jack of All Trades feature intended to apply to initiative? PS, congrats on a spectacular launch! Yes, Jack of All Trades can apply to initiative, since that roll is a Dexterity check.

— Jeremy Crawford (@JeremyECrawford) August 21, 2014

@vamp7777so it would also apply to concentration checks No. Jack of All Trades benefits ability checks, not saving throws. @tragicjones @mikemearls

@bjrollet @mikemearlsDoes Quicken allow a sorc. to cast 2 reg. spells a round or is the second spell cantrip only, as on pg 202 PHB? A spell affected by Quickened Spell follows the normal rules for a bonus action spell (PH, pg. 202).

— Jeremy Crawford (@JeremyECrawford) November 15, 2014

@JeremyECrawford OK so does that mean it has to only be a cantrip or can it be a leveled spell for the quickened.

— Harold Houck (@HHouckFamily) May 15, 2017

Quickened Spell turns a 1-action spell of any level into a bonus action. Want to cast another spell? See "Bonus Action" (PH, 202). #DnD https://t.co/o61DDyKYn3

— Jeremy Crawford (@JeremyECrawford) May 15, 2017

@HHouckFamilyOK so Cantrip only For the second spell, yes.

@wax_eagle @JeremyECrawfordCould I get some clarity on thieves tools and lockpicking. Do you need the tools? Do you need proficiency? anyone can use tools, prof bonus adds if proficient. No tools, DM can say no check or disadvantage.

— Mike Mearls (@mikemearls) November 14, 2014

DMG p.103 “locked doors” entry states you must have the tools AND proficiency to pick the lock. Is this a typo, or specific over general? The specific always overrides the general.

— Jeremy Crawford (@JeremyECrawford) November 28, 2017

So, anyone can use thieves tools, but you have to be proficient to pick a locked door? What about a locked chest? Disable traps? Anyone can try, prof just means add bonus, unless lock/trap/dm expressly says otherwise

@mikemearls @JeremyECrawford @ChrisPerkinsDnD Is Sacred Flame really the only offensive Cantrip for Clerics? Seems highly restricting.

— John Appleton (@jaa0109) November 12, 2014

@jaa0109 @mikemearls @ChrisPerkinsDnDDo you see allowing access to one more offensive Cantrip based on Domain as unbalancing? A cleric can pick up other damaging cantrips by taking the Magic Initiate feat or by multiclassing.
