@JeremyECrawford Is it true there is no longer a "Hold" action in 5e? I know my Players virtually live by it, but I've seen many sources say you can no longer hold your action till later in the round.

There is no Delay/Hold/etc. action in D&D. When it's your turn, you either act or don't act.

If you decide to do nothing, I recommend taking the Dodge action.

If you want to act later in the round, use the Ready action. #DnD https://t.co/4Bx6cNvj0q

So just to clarify in text what I gather from the little bit of the podcast I listened to the PoO of a Self AoE isn’t considered a target? So Burning Hands and Lightning Bolt work with War Caster and Shield Master? Assuming only a single target in the area itself That's correct! Spells with a range of "Self (XYZ)" are in a special category, where each spell defines how its targeting works. Also, in the range rules (PH, p. 202, 3rd paragraph), the caster is intentionally not called the target of such spells.

I have a question about Magic Resistance from something like the Yuan-Ti Pureblood race. Does it only affect Intelligence, Wisdom and Charisma saving throws, or does it affect a saving throw for any ability score? Hi there! That Magic Resistance trait affects any saving throw against a spell or other magical effect. It's not limited to Intelligence, Wisdom, and Charisma saving throws.

This question relates to the SCAG errata regarding Booming Blade… does the monetary value of the component now negate being able to use your Pact of the Blade weapon or Shadow Blade in conjunction with Booming Blade?

— Baumer Goodtree (@BigBaumer) November 11, 2020

If a D&D warlock creates a weapon with Pact of the Blade, that weapon has the value indicated in chapter 5 of the Player's Handbook (the text of Pact of the Blade directs the reader to that chapter to choose the weapon).

Shadow blade, in contrast, weaves together gloom. #DnD https://t.co/aKwfyUduo3

Don’t suppose you’re willing to explain the reasoning, here? The Pact of the Blade feature instructs you to pick a weapon from chapter 5 of the Player's Handbook. There you find the information for the weapon you chose, including its gp value, damage, weight, and properties.

Also, what is the value of an Improvised Weapon in this regard? Is it based on the value of the object?

— Dave 🔂 (@Glistam) November 11, 2020

Items in D&D have the value specified for them in the "Equipment" chapter of the Player's Handbook. If an item doesn't appear there or in another rulebook, the DM determines that item's value, if any. #DnD https://t.co/KsrskTh5p6

The Shadow Blade itself says “It counts as a simple melee weapon with which you are proficient.” All simple melee weapons are given a value as per Chapter 5 of the Player’s Handbook, and all those values allow it to work with the new version of Booming Blade.I can't stop finding ways to make it work, all RAW and supported by Jeremy's rulings (per the warlock pact weapon and improvised weapons).

— Dave 🔂 (@Glistam) November 12, 2020

As DM, I'd totally let the combo work. Shadow Blade creates a simple melee weapon, and if another rule cares about that weapon's value, I'd pick a value from the list of simple melee weapons in the Player's Handbook and apply that value ad hoc to the shadowy blade.

When a D&D rule uses the word "can"—as in "you can give high fives to up to three creatures within 5 feet of you"—it means you are able to do the thing. "Can" doesn't mean you must do it. #DnD

But if you don’t, I’ll be really sad you left me hanging, bro. 😢 Here's one for you! 🖐️
