@JeremyECrawford If a Rogue, with the Reliable Talent feature, rolls a nat 1, does it fail? Or is it a 10?

— Dan Conley (@Dan_conley19) October 23, 2016

It's not an automatic failure if you make an ability check and roll a 1 on the d20. 1 = a miss for an attack roll. #DnD https://t.co/ZpjHoVtIkV

@jasonshamblin @Dan_conley19Thank you, Mr. Crawford. Never liked the idea of crit fails or a magic 1/20 chance to succeed at ANY check. We especially don't want automatic success on ability checks. There are things you simply can't do or know.

@JeremyECrawford @Dan_conley19 conversely does a natural 20 mean an automatic success on an attack or skill check regardless of DC or AC?

— RATPTO1 (@ratpto1) October 24, 2016

In the core rules, rolling a 1 or 20 on a d20 has a special rule only if you're making an attack roll or a death saving throw. #DnD https://t.co/Kdi0fRM20W

@JeremyECrawford What's the DC to cast a spell from a scroll not on your class list? DMG pg 139 says anyone can cast & pg 140 mentions a DC.

Take a look at the description of spell scrolls (DMG, 200) for how they work. #DnD https://t.co/20zSpfDrUW

@JeremyECrawford Sage Advice question:
Does the thaumaturgy cantrip open a stuck, unlocked door?
Thanks in advance for the answer!

— Chris (@MikotoKondou) September 19, 2016

Thaumaturgy is meant to open unstuck, unlocked doors or windows, not stuck or locked ones. #DnD https://t.co/9HeSBNUXK2

@jeremyecrawford Is the grease from the Grease spell flammable? How much damage a creature covered in said flaming grease take?#dnd

— Pandantic (@Pandantix) May 26, 2016

If the grease spell created a flammable substance, the spell would say so. It doesn't say so. #DnD https://t.co/CuLZl4XDmq

— Jeremy Crawford (@JeremyECrawford) June 4, 2016

IMHO, if a spell does not mention a subject, go with the rule of cool. Burn that grease up! #dnd home rules FTW https://t.co/WdwKYM5E6c

House rules—the search for what's fun for a particular group—do, indeed, overrule official rulings. #DnD https://t.co/UPjyA8sZQH

— Jeremy Crawford (@JeremyECrawford) June 4, 2016

@JesterOC Having standardized rules for organized play is essential as well. Thanks for taking your time to make #dnd better for all You're welcome!

@JeremyECrawford pass without trace:can different targets be selected each round for the duration or are only the initial targets afffected?

— X (@x93temp) June 27, 2016

Pass without Trace: you can choose different targets throughout the duration. #DnD https://t.co/YmBWv7AqUc

If you shove/push a creature into Wall of Fire, Spirit Guardians, Spike Growth, etc, do they get affected?

A push is an effective way to force a creature to enter an area of effect, unless it requires willing movement. #DnD https://t.co/Zj1x7MSV7F

@JeremyECrawford What happens when you cast Produce Flame and want to grapple with a hand that is on fire? Is this hand considered not free?

— Philipp Mordashev (@PhilMordeshev) November 1, 2016

Produce flame—the flame doesn't prevent you from using the fiery hand. #DnD https://t.co/gQtrYrje9S

@JeremyECrawford Hello, Almighty! Does the Remarkable Athlete feat from Champion Fighter Archetype gives you plus to initiative?

— Roman Kitar (@RomanKitar) September 13, 2016

Remarkable Athlete benefits Dex. checks that don't use your prof. bonus. Initiative is a Dex. check (PH, 189). #DnD https://t.co/1upM7BZKyO
