@JeremyECrawford Can a Wizard 'copy' a cantrip scroll, and add it to his spellbook? That way it's added to his list of known cantrips?

A spell of 1st level or higher goes into a wizard's spellbook, whereas a cantrip is fixed in the wizard's mind. https://t.co/Gx9gtULz44

@GX_Sigmaso can he just look at it and memorize it?
No, a wizard learns a cantrip only when a feature says he or she does.

@GX_Sigma it seems weird that cantrips are the hardest spells in the world to learn. Shouldn’t they be the easiest?
A cantrip is special: it grows in power as you do, and it is magically bound to you. In most D&D worlds, that bond isn't easy.

@BrailSays
@GX_Sigma @JeremyECrawford I think of it like music;I was able to play lots of songs with the sheet in front of me,but fewer from memory. That's an excellent analogy! @GX_Sigma

@GX_SigmaThat’s a reasonable house rule, which I think a number of groups would enjoy. That's a reasonable house rule, which I think a number of groups would enjoy. @BrailSays

@PlaguescarredHi Jeremy, does a melee weapon that is thrown count as ranged? I.e Do Archery Fighting Srtyle work wt thrown dagger? The Archery feature is intended to work with ranged weapons. A dagger is a melee weapon even when you throw it.

@VandalHeart "does the damage dice from Hex double on a critical?" Yep.

@GX_Sigma "What is the intended rule? Round up for HD? Minimum 1 for HD?" @JohnnyZemo Minimum of 1

@Vinceborg2050The third bullet of the grappler feat refers to a rule that doesn’t exist. What would you suggest to fix it? The bullet simply shouldn't be there. It erroneously refers to an old version of the grappling rules.

@xanderh2404Is Eldritch Knights being unable to use a spellcasting focus intentional? Do they have to use a component pouch? An eldritch knight or an arcane trickster uses a component pouch.

@JeremyECrawford Forgive me if this has been answered. Does chill touch prevent a creature from gaining temporary hit points?

— SlyFlourish.com (@SlyFlourish) June 8, 2020

An effect in D&D that prevents you from regaining hit points doesn’t stop you from gaining temporary hit points.

This means a spell like chill touch, which can prevent healing, has no effect on temporary hit points. You can think of D&D's temporary hit points as an extra layer of resilience, which showed up to the game in a hit point suit. Whatever's inside that suit (a force field, a bit of courage, or something else) provides real protection, but it's not real hit points. #DnD

— Jeremy Crawford (@JeremyECrawford) June 9, 2020

If your D&D group struggles with the definition of temporary hit points, consider calling those points something else; durability points and toughness points are two possibilities. I've found that kicking "hit points" out of the name often helps new players get it. #DnD

— Jeremy Crawford (@JeremyECrawford) June 9, 2020

I forget if it was 4E or 5E, but one of the PHBs specifically said hit points were an intentionally abstract concept and I always liked that. It makes fights feel more heroic to know folks aren't constantly knicking one another with swords until one takes a fatal papercut 😝

— Nick Wester, P.I. (@WeHaveSnacks) June 9, 2020

Hit points in D&D represent more than physical health. Here's the first sentence of the rule on hit points in the Player's Handbook: "Hit points represent a combination of physical and mental durability, the will to live, and luck." #DnD https://t.co/yotN9eIXTS

— Jeremy Crawford (@JeremyECrawford) June 9, 2020

With that in mind, why does a character's Hit Points total rely only on Constitution modifiers, instead of Con, Wisdom, Dexterity and [insert Luck based modifier here]?

— Jez Gordon (@GibletBlizzard) June 9, 2020

Your hit points in D&D are determined by your level, your Constitution modifier, and dice. In D&D, dice represent the whims of fate. #DnD https://t.co/c1HZzGCHt6

@JeremyECrawford
Does using the Ready Action also prevents you from using a Bonus action in your turn, or you just transform an Action (normal) to Reaction (Readied Action)? #DnD

The damage of the Psi Warrior's Psionic Strike occurs after the attack that delivers it. That damage is therefore not rolled twice on a crit. #DnD https://t.co/XgSP4OCplr

I cannot for the life of me understand how this does not violate Combining Game Effects. Same name and the first three paragraphs are verbatim copies of one another. @JeremyECrawford can you explain why Psionic Powers doesn't have to adhere to Combining Game Effects?

— Eric Green (@quadhund) November 26, 2020

The two Psionic Power features are meant to be exceptions to the rule on combining game effects. The "detailed below" wording was meant to convey their exceptional nature, but we could have been even clearer about it.
