@JeremyECrawford When the Stunned condition says Saving Throws, does that also count towards ability checks such as to resist grapple?

— James Patrick (@SsinssrinnDM) August 2, 2016

Something that applies to saving throws affects ability checks only if it says so. Saves & checks are different #DnD https://t.co/1IwwMNnHCu

@JeremyECrawford for death saves, rolling a 1 is 2 failures, but if I have Bless I can only roll a minimum of 2, this prevents 2 failures?

— Jeremy Graten (@JeremyGraten) October 13, 2016

Death Saving Throws: you suffer two failures if you roll a 1 on the d20 (see PH, 197). Modifiers to the roll don't matter here. #DnD https://t.co/4bP0jwxgct

@JeremyECrawford Could a 9th level monk grapple an enemy, and then use unarmored movement to move that enemy up a wall? Perhaps dropping it?

The rule on moving a grappled creature (PH, 195) works with movement of any sort. #DnD https://t.co/Wmx6bLBpHK

@JeremyECrawford Can you cast AOE spells (IE fog cloud) so they effect an area 1 or 2 squares off the ground (IE to confound flying NPCs)?

— Jeramy M. Pappas (@JMPappa) August 25, 2016

An area spell tells you if it must target an area on the ground or if it has some other targeting limitation. #DnD https://t.co/PLMzDnhDc0

@JeremyECrawford What exactly can I do with the Dexterity (Sleight of Hands) check granted by the Rogue/Fast Hands feature?

— Leonardo Raele (@LeonardoRaele) October 26, 2016

See the "Using Each Ability" section in the Player's Handbook (p. 175–9) for what Sleight of Hand and other skills can do. #DnD https://t.co/fFNIayRTNs

@JeremyECrawford If I Dispel Magic one of many creations from a 'Conjure ???' Spell, does the entire spell end, or just that one creature?

— Airatome118 (@Airatome) November 15, 2016

If you cast dispel magic on a creature, the spell affects only that creature. If you cast it on an object, it affects only that object. #DnD https://t.co/PLmvn2JDi6

@JeremyECrawford I've heard that creatures from the Bag of Tricks lasts for 10 minutes or until the next day. Could you clarify for me plz?

Bag of tricks—the DMG errata clarifies the duration of this magic item: https://t.co/7cBE3UUIDe #DnD https://t.co/EZMejG44Ll
