How does Subtle Spell works on spells like Friends and Charm Person (where it is explicitly said that the target knows that he was charmed)? Maybe, after the social interaction, the targets know they were charmed but they have no idea about who has charmed them?

Subtle Spell can remove the somatic and verbal components of a spell. That feature has no effect on any other aspect of a spell.

For example, charm person says the target knows you charmed them. Subtle Spell has no effect on that statement. #DnD https://t.co/MFwCVt7omX

@JeremyECrawford @SageAdviceDnD Fire Shield: do you choose shield type (warm/chill) when you cast it? Can you change shield type during the spell's duration? RAW there is no wording, seems to indicate you can change shield type at any time, even without an action. What's the RAI?

SPELL: FIRE SHIELD
The intent is that you choose the flames' nature—warm or chill—when you cast the spell. #DnD https://t.co/rEMcsx0EVS

@JeremyECrawford if you're supposed to roll one d4 for damage on Magic Missile how does that work with the goblin ability Fury of the Small each Missile or just one? Also with an AoE spell does FotS add damage to the spell for all effected ceatures?

— Bren Pumpkaboo Pie (@Coppercredit) October 10, 2018

The goblin's Fury of the Small trait affects only one creature, and the trait deals a flat amount of damage to that creature, an amount equal to your level. #DnD https://t.co/js3b97Reyb

If I’m a druid and cast absorb elements as a bonus action, land in a fire, then use my wild shape to change into a bear, do I still gain the bonus damage to my next attack roll? Do I also benefit from the resistence?Absorb elements requires your reaction, not a bonus action.

When using mirror image. Does an attacker who targets a mirror image instead of you provoke an attack from the Sentinel feat? Yes.

Hey @JeremyECrawford can the Revised-Ranger take any Ranger Subclass? Or were the ones in XGTE designed for the PHB Ranger class? Or doesn't matter? 🙂

— Mat, but Spooky (@_Matafer) October 5, 2018

Subclasses in official products are designed for the game's official classes.

Unearthed Arcana material isn't official. If you'd like to use UA content with official options, go for it! It's all essentially homebrew. #DnD https://t.co/s2DGQUjVC2

@mikemearls @SageAdviceDnD @JeremyECrawford Do eladrin player characters count as fey like they do in MToF for spells like Detect/Dispel/Protection from Evil and Good?

— The Spooky Matt 🎃 (@MattNeutral) October 15, 2018

Playable elves are humanoid. Some of their kin are fey.

The playable eladrin in "Mordenkainen's Tome of Foes" are an elf subrace and are therefore humanoid. If they had a different creature type, they would have a trait that said so. #DnD https://t.co/ySU1DWu6OC

@JeremyECrawford When Divine Strike says "weapon strikes" is that flavor text or does it mean you can't use it with an Unarmed Strike? 1

— Dave Williams (@DaveWil33) October 11, 2018

When Divine Strike says "weapon strikes," it means weapon strikes. #DnD https://t.co/9xgGtWFd0B

— Jeremy Crawford (@JeremyECrawford) October 11, 2018

So to be clear (because lawd knows it needs to be chrystal) that's a no on Unarmed Divine Strike?

— Dave Williams (@DaveWil33) October 11, 2018

Unarmed strikes aren't weapons. If a rule refers to you using a weapon, that means something other than an unarmed strike. #DnD https://t.co/qrJp3w94TP

— Jeremy Crawford (@JeremyECrawford) October 11, 2018

However, do you find anything unbalancing in allowing it?

— John Appleton (@jaa0109) October 11, 2018

You're unlikely to break the game if you use unarmed strikes with features designed for weapons, but some unintended consequences might arise, since we didn't design those features to be used with your body. And we like to avoid encroaching too much on the monk's domain. #DnD https://t.co/opRGejk7Wx

— Jeremy Crawford (@JeremyECrawford) October 11, 2018

In particular, Divine Smite gives +1d8 damage per hit, and flurry of blows allows for +2 attacks per round; a Monk/Paladin can therefore trigger than +1d8 up to 4 times per round, rather than the 2 from Extra Attack (or 3, with two-weapon fighting)

— Thomas "You Can Call Me Tom" (@thomasabarry1) October 11, 2018

The tweet below is a great example of the sort of unintended consequence you get in D&D if you ignore rules that say "weapon" and use your body instead. #DnD https://t.co/YrDWtS40f0

— Jeremy Crawford (@JeremyECrawford) October 12, 2018

That implies Stunning Strike cannot be used on an unarmed strike, which does not seem like the correct result.

— Rob Wallis (@ghezbora) October 12, 2018

The rule on unarmed strikes specifically states that they can be used to make a weapon attack (a process). They still don't count as a weapon (an object). #DnD https://t.co/xIA2w6hYh3

— Jeremy Crawford (@JeremyECrawford) October 12, 2018

That is poor word choice that leads to the confusion. A weapon attack implies use of a weapon, especially with unarmed strike as a separate phrase. If an unarmed strike counts as a weapon attack, it implies the unarmed strike is also a weapon. This is how English works.That is indeed how English works, which is why the rule on unarmed strikes clarifies that these non-weapons can be used to make weapon attacks. The exception is explicit.

— Jeremy Crawford (@JeremyECrawford) October 12, 2018

I’m not arguing your ruling, I’m just saying peoples confusion in this area is justified and using less confusing language in future editions would be helpful to avoid this confusion. I agree.

— Jeremy Crawford (@JeremyECrawford) October 12, 2018

Unarmed strikes are not considered weapons, even though they are considered weapon strikes. Unarmed strikes can be used to make weapon attacks. "Weapon attack" is a rules term, just as "spell attack" is a rule term.

"Weapon strike" is just English.

— Jeremy Crawford (@JeremyECrawford) October 12, 2018

So a “weapon strike” requires a weapon but a “weapon attack” can be unarmed? That is… unintuitive… That's why the rule on unarmed strikes points out this exception. It's not something you'd expect, but the rules say, "Go for it!"

— Jeremy Crawford (@JeremyECrawford) October 12, 2018

Okay, this has been confusing me for a long time and I’m still not 100% clear, so I’ll ask it right out: Can Stunning Strike trigger off of an unarmed melee attack? Yep.

— Jeremy Crawford (@JeremyECrawford) October 12, 2018

wait what? but unarmed strike is listed in on weapons table as a simple melee weapon on PHB 149. And if it isn't a simple melee weapon do monks (or anyone else) never get prof bonus for unarmed attack rolls?

— Teao (@Questionor) October 12, 2018

Unarmed strikes originally appeared on the Weapons table in the "Player's Handbook." That was an error, which was corrected in the book's errata years ago and in all recent printings.
