Can a Cleric use Harness Divine Power without a Holy Symbol?

Harness Divine Power states (TCoE p.30):

As a bonus action, you touch your holy symbol, utter a prayer, and regain one expended spell slot […]

Does this mean this ability can only be used provided the Cleric has a holy symbol? In the Spellcasting feature for Cleric’s it says "You can use a holy symbol,[…]" which should mean they can cast spells with materials, they are not forced to use a holy symbol; if a player chooses to make a character that uses materials instead of a holy symbol, are they locked out of using this feature?

How to add the vector symbol on a letter?

Ho to add the vector symbol on a letter like this: $ \vec{r}$ ?

Consider the following code:

k0 = Graphics[{Text[      Style["\!\(\*SubscriptBox[\(K\), \(0\)]\)", 12], {0.5, -0.05}],      Thick, Arrow[{{0, 0}, {1, 0}}]}]; k1 = Graphics[{Text[      Style["\!\(\*SubscriptBox[\(K\), \(0\)]\)-q", 12], {0.5, 0.2}],      Thick, Arrow[{{0, 0}, {0.8, 0.2}}]}]; q = Graphics[{Text[Style["q", 12], {0.9, 0.15}], Thick,      Arrow[{{0.8, 0.2}, {1, 0}}]}]; l = Graphics[{Text[Style["\[Theta]", 12], {0.2, 0.03}], Thick,      Line[{{0, 0}, {0.2, 0}}]}]; Show[k0, k1, q, l, Boxed -> False] 

Can a creature under the effect of a Discord Symbol perform verbal spell components?

Symbol allows you to create a magical glyph that triggers on a condition you determine. One of the glyphs you can create is called Discord:

Each target must make a Constitution saving throw. On a failed save, a target bickers and argues with other creatures for 1 minute. During this time, it is incapable of meaningful communication and has disadvantage on attack rolls and ability checks.

Is a creature who fails the save against this effect capable of performing verbal spell components?

Do you need a free hand for your holy symbol if you’re wearing it visibly?

I’ve been creating a Paladin who uses the Defense fighting style while wielding two weapons (instead of the more common Dueling style with weapon and shield). However, I was worried that spell components would make this too difficult because the character wouldn’t be able to use a shield emblazoned with a holy symbol as their spellcasting focus. However, I reread the section on holy symbols and it says the following:

A cleric or paladin can use a holy symbol as a spellcasting focus, as described in chapter 10. To use the symbol in this way, the caster must hold it in hand, wear it visibly, or bear it on a shield. [PHB pg. 151, emphasis added]

By my reading of this, even absent a shield, the caster does NOT need a free hand for their focus. Simply wearing it on a chain outside their armor or clothing (or even affixing it to the outside of their armor) would be sufficient.

This surprised me, so I double-checked the material components section:

Casting some spells requires particular objects, specified in parentheses in the component entry. A character can use a component pouch or a spellcasting focus (found in chapter 5) in place of the components specified for a spell… A spellcaster must have a hand free to access these components, but it can be the same hand that he or she uses to perform somatic components. [PHB pg. 203]

At first glance, its seems that the statements "A character can use… a spellcasting focus… in place of the components specified for a spell" and "A spellcaster must have a hand free to access these components" would logically mean that a spellcaster must have a hand free to use a spellcasting focus.

However, is this a case of "specific beats general"? Using an arcane focus requires a free hand because it follows the general rule from pg. 203, but a holy symbol doesn’t as long as it’s visibly worn as written in the more specific rule on pg. 151?

(Related: Do these spellcasting foci from Xanathar’s Guide to Everything have to be held in a hand?)

Can a weapon be a holy symbol?

So I’m being part of a DnD campaign soon, and I’m making a tempest cleric that worships Thor. Since Thor’s weapon is a Warhammmer, and I also use a Warhammer, could the hammer count as a holy symbol or would there need to be some form of engraving/emblem on it for it to count?

[ Politics ] Open Question : Trump Slams NYC Black Lives Matter Mural As Symbol Of Hate?

NYC is cutting Police [budget] by ONE BILLION DOLLARS, and yet the [Mayor] is going to paint a big, expensive yellow Black Lives Matter sign on Fifth Avenue, denigrating this luxury avenue,” the President objected. “Maybe our GREAT Police, who have been neutralized and scorned by a mayor who hates [and] disrespects them, won’t let this symbol of hate be affixed to New York’s greatest street,” he continued. “Spend this money fighting crime instead!” That is one thing Black Lives Matter and de Blasio have in common – their hatred of the police.

What is the lore behind why soul coins have the symbol of Bhaal on them?

I am struggling to find an image of both sides of a Soul Coin (Baator’s currency), but everywhere I’ve looked, I’ve only found only one side bearing a letter and the other side depicting a skull with blood droplets flying around it.

But it is the symbol of Bhaal. Why does it appear on Baator’s currency?

Am I correct about how soul coins look? What images appear on the sides of a soul coin, and why?
