If a wild magic barbarian uses their ability to restore a spell slot to a warlock, does it only work if they can hit the warlock’s only spell slot level on the d3? That's correct.

@JeremyECrawford Can the new metamagic option Seeking Spell be used on the Green Flame Blade cantrip's attack roll after a miss? Essentially giving you "optional" advantage?

— Jacob Vogelhut (@jvogelhut) December 10, 2020

The Seeking Spell metamagic option can be used with the attack roll of any spell.

Cantrips are spells, so Seeking Spell can be used with cantrips, such as Green-Flame Blade. #DnD https://t.co/KuJ6FAv93B

What is the intention between Booming/Green-flame blades requiring a weapon with a value of at least 1sp, when no weapon (in PHB at least) has a value below 1sp?

— Zem (@TheRealZem) November 13, 2020

If a D&D spell’s material component lacks a monetary value and isn’t consumed, you don’t need that component; you could substitute a component pouch, for instance.

Booming/Green-Flame Blade need a weapon with a monetary value because they require an actual weapon. #DnD https://t.co/OTB8kTvQBo

— Jeremy Crawford (@JeremyECrawford) November 13, 2020

So removing the Shadow Blade option is fully intentional? I took the opposite intention out of this. What he seems to be describing is that the spell requires a weapon and that you can't sub out the "material component" for an arcane focus or component pouch. Shadow blade seems like an unintended consequence.

— Brett Richards (@brett_play) November 13, 2020

You're exactly right, @brett_play. The component entries of the two spells were simply incorrect; they didn't follow the rules for how components work. We've corrected them and, as a consequence, some combos that never should have worked no longer work.

— Jeremy Crawford (@JeremyECrawford) November 13, 2020

Okay now I’m the one confused. I know in one of your earlier replies, you talked about allowing booming blade and shadow blade to work together. Was removing this interaction intended? Or is it simply how it works now by RAW to standardize wording but isn’t a balance concern. This change has nothing to do with prohibiting or allowing Shadow Blade to combine with Booming/Green-Flame Blade. It's about fixing those two cantrips. As DM, I'd allow those them to combo, since I make liberal use of the rule on improvised weapons.

Hey @JeremyECrawford , if a Peace Cleric uses Protective Bond, and the raging barbarian uses its reaction to take the piercing damage in place of his ally, does he take full damage ou half because of his rage?

— Pedro Filippo 💙💭 (@FilippoPedro) December 2, 2020

If you use the Protective Bond feature in Tasha's Cauldron of Everything to take damage that was meant for someone else, any resistances, vulnerabilities, and other damage modifiers you have apply to the damage you take, as normal. #DnD https://t.co/Rbs51rT0U4

Hey @JeremyECrawford we fans or @dndoptimized wanna know if Custom Lineage Characters who are part elf can get the Elven Accuracy Feat. Basically can customs use racial feats if it falls in line with their backstory?

— Cumrade Corvus (@XCorvus777) March 3, 2021

In Tasha’s Cauldron of Everything, the custom lineage option is chosen in lieu of a race, such as elf or dwarf. If you choose the custom lineage, you don’t qualify for things in the game that require elf, dwarf, and the like. In contrast, if you're an elf and customize your origin (using the option in Tasha's Cauldron of Everything), you're an elf and qualify for elf things. #DnD

— Jeremy Crawford (@JeremyECrawford) March 4, 2021

Customizing your origin and choosing a custom lineage are two rules, addressing different needs. One is about making your elf/dwarf/etc. the way you want them. The other is about making a character who isn't mechanically attached to any particular species in the game. #DnD

— Jeremy Crawford (@JeremyECrawford) March 4, 2021

So I think the issue here is you’re saying mechanics, but people are imagining ancestry. So the custom lineage character isn’t attached to a species, but how did they come about. Are people allowed to say it’s part elf/part orc/part dragon etc? The custom lineage option allows you to create whatever ancestry you'd like for your character. It's a toolbox option. You could be the child of an orc and an elf, for example. Whatever story you tell, the rules consider the character's race to be "custom lineage."

— Jeremy Crawford (@JeremyECrawford) March 4, 2021

Does this feel even more divisive? or is it just me?

No, you’re not an elf, nor a dwarf… It's not for making your own personal version of an elf. It's for making something you want to play that isn't an existing race option.

@JeremyECrawford does a College of Creations bard have the ability to create spell components with their Performance of Creation ability? Especially at 14th level, am I able to make enormous consumable diamonds? #dnd #tashasCoE

— Rolling With Disadvantage Podcast (@RWDPodcast) December 2, 2020

The Performance of Creation feature in Tasha's Cauldron of Everything can create objects that are usable as the material components of D&D spells, as long as you abide by the limitations in the feature. #DnD https://t.co/iTLTJ2ph3E

— Jeremy Crawford (@JeremyECrawford) December 5, 2020

What about alchemical ingredients? Or… gunpowder? Constructed items like a wheelbarrow?Are those allowed? You can use Performance of Creation to create anything that abides by the limitations in the feature.
