How do you work morale in 5th ed?

— Dustin Reader (@KiltedNTilted) November 2, 2016

There's an optional rule for morale in the DMG. As DM, I roleplay the morale of monsters and NPCs. #DnD https://t.co/9Fa2ZliTfw

@JeremyECrawford does heavy armor master affect damage done from traps? (I.e falling rocks bludgeoning DMG)

— Brian Daniel Smith (@bdsmith1986) October 7, 2016

Heavy Armor Master only reduces bludgeoning/piercing/slashing damage from nonmagical weapons. #DnD https://t.co/M51pMrjbKN

@JeremyECrawford Does that mean it's useless against natural attacks (claws, bites, slams, etc.)?

— Rick Kittenhugs (@thekittenhugs) October 8, 2016

If a natural weapon is nonmagical, Heavy Armor Master works against it. #DnD https://t.co/1RU3yq8E6X

Does a Nat 20 on a skill check=a Critical (automatic) success?

Rolling a 20 on a d20 is an automatic success only for an attack roll, not for an ability check or a save. #DnD https://t.co/I0Iq4Nms4T

@JeremyECrawford But it should be a success. If a natural 20 isn’t a success, then there’s no point in allowing the roll in the 1st place.

@devilmonkey77 @TJBoardexactly! If the only chance you have is to crit a success then there is no other way of doing it. So no point. Some DCs are impossible for certain characters to hit. Working as intended.

@JeremyECrawford Isn't a saving throw because your physically or mentally trying to resist an effect? If so why no rule to choose to fail?

— Steven Connor (@Mazoshi1987) October 25, 2016

Effects that involve saves are intended for you to use on others. If you use one on yourself, you're in DM-adjudication territory. #DnD https://t.co/0K5XAPTCIz

@JeremyECrawford D&D question: Shield of Faith requires a bonus action to cast, but paladins&clerics in the PHB don't get a bonus action —

— Noëlle Anthony (@noellejoyeuse) August 27, 2016

A spell/feature that can be used as a bonus action gives you the ability to take such an action (see PH, 189). #DnD https://t.co/DS2fJ9Kb6H

— Jeremy Crawford (@JeremyECrawford) August 27, 2016

@JeremyECrawford @noellejoyeuse is there a reason RAW isn't "you always have a bonus action but just nothing to spend it on?"

— Joran Dox (@NightFantomJ2) August 27, 2016

We don't want play slowed: "What should I do with my bonus action?" You have one to use or you don't. #DnD https://t.co/4F9LY3v1v8

Does Great Wepon Fighting fighting style let you reroll all of the attack’s damage dice or just the weapon damage dice?

The intent is that Great Weapon Fighting lets you reroll just the weapon’s dice, not Smite dice and the like. #DnD https://t.co/GCojfPXbPc
