@SaulsterCan A character fire ranged/spell from cover and duck behind again making them impossible to hit? Yes.

@JeremyECrawford if a Swashbucker use Fancy Footwork to get out of range of a creature with the Sentinel feat, it will provoke an AoO?

Fancy Footwork creates an exception; it denies another creature the ability to make opportunity attacks against you. #DnD https://t.co/SIBdlAaQjT

@ashparnellhow? The swashbuckler is extraordinarily slippery and makes the attacks nonviable.

@JeremyECrawford Q that came up at game tonight, does spiritual weapon threaten the square it's in for attacks of opportunity?

— Ed Robinson (@Lwnasidh) February 25, 2016

The spell's description would say if the spiritual weapon made opportunity attacks. It intentionally doesn't. #DnD https://t.co/PbR9Dc0ixP

@JeremyECrawford Quick followup question: If you personally aren't casting the spell through a staff, how can it use your ability mod?

— Kevin Kost (@kpkost) August 27, 2016

If a magic item tells you to use your spellcasting ability, you do. If it doesn't, you don't (see DMG, 141). #DnD https://t.co/0Suc7v2lzT

@JeremyECrawford An Assasin rogue gets an automatic crit on surprised foes, can it take the +10 to damage from Sharpshooter in this instance

— Blake Holtsbaum (@WhaleliamBlake) June 15, 2016

Assassinate upgrades a hit against a surprised target into a critical hit; you still have to roll. #DnD https://t.co/uHe8hCFHO5

@JeremyECrawford Just by the lack of it being mentioned am I to assume that disintegration spell does nothing on a successful saving throw??

— kevin maze (@itssosublime) December 11, 2015

A spell doesn't do anything to a target on a successful save unless its description says it does. #DnD https://t.co/YoUdf8FqxY

@itssosublimeThat’s the way I understoodit just wanted to double check with one of the archmages of the arcane… Thank you sir!! No problem!

@johnnysmithdnd @mikemearls does reach feature of whips and polearms allow use with cantrips like booming blade, green flame blade at 10′? The reach of those weapons doesn't change the range of those spells.

@JeremyECrawford Does the Arcana Cleric's Potent Spellcasting add +WIS mod damage to the 1st target of Green-Flame Blade, the 2nd, or both?

— Daniel Branton (@danthebran) June 28, 2016

Potent Spellcasting adds to dmg. dealt by a cantrip. GFB: add to 2nd target, then to both targets at 5th lvl. #DnD https://t.co/6J5W53omWB
