@JeremyECrawford When spells are "centered on a point" does that allow the point to be between tiles on a battlemat? Ex. Cloud of Daggers

Take a look at the rule on areas of effect in the DMG. A point of origin is positioned on the corner of a square. #DnD https://t.co/b3uhyGpfkR

@JeremyECrawford How does the second feature of the Sentinel Feat work with weapons that have reach?

— Susan Stoddard (@valoriclight) October 25, 2016

The second benefit of the Sentinel feat works with your reach—whether it's 5 feet or 10 feet with a reach weapon or something else. #DnD https://t.co/VpFF5CA9ur

@JeremyECrawford if using a weapon with reach is it only at the 10ft range or can it be at the 5ft range as well? Thanks for responding.

— Susan Stoddard (@valoriclight) October 26, 2016

If you want to make an opportunity attack with a particular weapon, the attack is triggered when a foe leaves the reach of that weapon. #DnD https://t.co/uO4bTeR3Qf

@JeremyECrawford Does a Druid retain his Barkskin spell after he shapeshifts?

— John Bard (@dmjohnbard) September 21, 2016

The text of barkskin doesn't say the targeted creature must be humanoid. Changing creature type doesn't end it. #DnD https://t.co/tonualoyBW

@JeremyECrawford The issue comes about from the "replace your game statistics" line. People keep interpreting that as negating spells. :/

— Dan Dillon (@Dan_Dillon_1) September 21, 2016

"Replace your game statistics" in polymorph effects refers to your character's statistics, not the effects of a spell or a magic item. #DnD https://t.co/HVbpcgEz7z

@JeremyECrawford 'Nondetection' spell. Can it prevent 'See Invisibility' spell? Does it prevent all divination magic?

— Pavel (Ankheg) (@silvester_boots) October 7, 2016

The nondetection spell hides you from divination magic. See invisibility is a divination spell. #DnD https://t.co/pBLhSdKFLP

How do bonus action spell rules go when a noncantrip is cast as a single action then a bonus action spell?

If you cast a spell of 1st-level or higher with 1 action, you can't then cast a bonus action spell. #DnD https://t.co/gXVPr4Xtk5

— Jeremy Crawford (@JeremyECrawford) January 29, 2016

@warderbradBut this is not how the rules read, is there Errata to address that? The rule says you can't cast a bonus action spell and a noncantrip (a spell of 1st level or higher) in the same turn (PH, 202).

— Jeremy Crawford (@JeremyECrawford) January 29, 2016

do you have to manipulate cost components if you have a focus?

— Zasabi (@zasabi7) June 26, 2016

Having a spellcasting focus is irrelevant to a spell that requires a component with a cost. #DnD https://t.co/9t94JdE9tX
