BBEG casts a spell, I counterspell, and the mob has a chance to counterspell my counterspell under normal circumstances, leading to a wasted slot and some hurt from the incoming spell.  If however I cast counterspell with subtle metamagic, am I right in thinking that this counterspell itself cannot be counterspelled as there is no way to identify that i'm casting this spell?  Subtle casting: "When you cast a spell, you can spend 1 sorcery point to cast it without any somatic or verbal components."

Counterspell   1 reaction, which you take when you see a creature within 60 feet of you casting a spell.   Can I Counterspell a creature that completely eliminates component requirement?     Subtle Spell   When you cast a spell, you can spend 1 sorcery point to cast it without any somatic or verbal components.   If the spell is subtle then can I see it’s being cast in order to counterspell it?

I would like to know what happens if you use the Magic Jar spell to possess a creature which is capable of casting spells. Below are 3 different situations. I post all these questions in the same question because all of them are heavily related.  1st Situation: Creatures with Innate Spellcasting.  For example Kraken Priest (MM 215).  Would I be able to use its Innate Spellcasting? I mean, being able to cast its spells as the creature does (X uses per day). I don't say using my spell slots because that is impossible (eg. a Drow Elf Warlock can't use its spell slots to cast Darkness).  2nd Situation: Creatures with Spellcasting (similar to Pact Magic).  For Example Warlock of the Archfey (MM 219).  Would I be able to use its spellcasting? Note that this creature is an "11th-level spellcaster", not an "11th-level warlock" (its spellcasting isn't a class feature).  What would happen with the spell slots? Would I be able to cast its spells with my own slots? Would I be able to cast my spells with its slots?  3rd Situation: Creatures With Spellcasting (similar to Spellcasting of Clerics or Wizards)  For Example Diviner (MM 213).  Would I be able to use its spellcasting? Note that this creature is a "15th-level spellcaster", not a "15th-level wizard" (its spellcasting isn't a class feature).  What would happen with the spell slots (considering that for example, I'm a 16th-level Wizard)?   Would our spellcaster level sum (as if multiclassing)? Should I use the highest spellcaster level instead of summing them? Should I count the spellcaster level separated, each one with its spell slots separated? For example, Would I have 8 1st-level spell slots (4 + 4)?   Finally (without considering a specific situation):  Would I have to recalculate the spell's attack bonus and spell's DC if my mental stats are different from the creature's stats?  I know that these are a lot of multiple questions, but I don't think that posting them separately would be beneficial. If you think so, let me know and I will do that.

This is a follow-on to   So, I have a spell, say Sanctuary, that is cast as a bonus action, yet requires Verbal and Somatic (and in this case Material, but that is taken care of by my character's holy symbol) components to cast.  Can my character take their off hand off their two-handed weapon (light crossbow) to cast this spell as the bonus action, then regrip the weapon with both hands in order to use it as the turn's regular action?  Or do they lose their regular action in order to regrip the weapon?

Imagine Wizard A tries to cast fireball. Wizard B casts  as a reaction to try to nullify said fireball.    Can Wizard C cast counterspell as a reaction to nullify Wizard B's counterspell? Can you have a group of Wizards of an indefinite population counterspelling each other ad nauseam?

Let's suppose I'm a wizard casting a ranged spell. An enemy is behind cover but I suspect he'll come out, so I ready an action to cast at him when he comes out; but I don't want to risk getting charged at by another enemy and losing concentration or taking disadvantage. Can I say:  "I ready a spell. When that guy over there leaves cover, or when any enemy gets within 5 feet of me, I will cast it on that enemy"?

Does a grease spell affect where the caster is standing, or the caster in general when cast on itself? I've read of some rules about AOE spells not affecting the point of origin or something... but would like to know RAW

Can magical spells actually damage objects?  So something standalone, e.g. the pile of wood over there in the corner of the room?  And on a character, e.g. the quarterstaff in a character hand?  [I think they can, but I'm concerned I'm confusing DnD 5e with earlier versions]

If I have cast something like Animated Objects or Bigby's Hand and then follow up the next round with casting Etherealness, can I still command/control those spells?

Charm Person has verbal and somatic components.  Is there anything in the rules as written that defines how obvious those verbal and somatic components are?  Would it be obvious the caster was casting a spell from 5 feet away?  From across a crowded room?  I'm specifically interested in an answer based on the rules as written, although interpretation and individual opinion are not unwelcome.

Last session, one of my players said he wanted to cast minor illusion - creating a high-pitched screaming noise - within the inner ear of a Worg. I ruled it was permissible, got the Worg to take a Constitution check to not be alarmed, and it succeeded, remaining unperturbed.  But I've since been thinking - could you cast minor illusion in such a small, specific location within combat? Could I perhaps rule that the PC should take a penalty of some sort? Is a Con check appropriate? What would the effects of such below-the-belt tactics be if they succeed?

Some spells have somatic and vocal components, that's well known.  How loud must a wizard talk? How obvious/wide should his gestures be?  Some spells that would be awesome would be fairly limited if you need to shout them (ex: mage hand, range 30ft).

says:     You create three glowing darts of magical force. Each dart hits a creature of your choice that you can see within range.    says:     You create the image of an object, a creature, or some other visible phenomenon....   If one caster creates an illusory creature with silent image what happens when another caster targets that illusory creature with magic missile?  Assuming of course that the mm caster is shooting first and asking questions later, ie, rather than using his or her action to investigate the illusion is simply choosing to attack it.  Or I suppose the magic missile caster might have failed the investigation check.  Either way, the magic missile caster believes the illusion to be real.  My own inclination would be to rule that magic missile would in fact appear to hit the illusory creature, but I can't find much to either support that conclusion, or to support another.

Some magic items allow you to cast spells using them, even if you are normally unable to cast such spells, such as the Wand of Magic Missiles or the Helm of Telepathy.  When you cast a spell with such a magic item, can you be visibly seen to be casting the spell? This is relevant to    Whether or not the spell can be Counterspelled Whether it is obvious to observers that any magic has occurred, if it's a spell like Detect Thoughts that has no visible effect after being cast.

Is it true that not even the person/creature/thing doing the initial action that starts a combat is able to use a full-round action?  According to all sources I can find, the initial attack already is part of the surprise round, so you're only entitled to a move action or standard action; but that leads to an (in my opinion) absurd scenario, so I just wanted to be sure whether there is something I'm missing:  Let's say sorcerer A is hiding in the bushes, 1HP left, waiting to finish sorcerer B (1HP left) off with magic missiles before B does the same to A. Then he suddenly spots sorcerer B - but sadly, he's some feet out of range. Now sorcerer A wants to use metamagic to double his magic missiles range and fire that on sorcerer B ... but now his magic missile takes a full-round action to cast, so sorcerer A cannot surprise sorcerer B with it anymore.  Is this interpretation right RAW-wise or am I missing something?

Let's say I have  and my one opponent has a  and no creatures in play. I might still want to cast Lightning Bolt to delve it later or to buff up my  or whatever. My question is...  can I cast Lightning Bolt without targeting anyone? Can I just decline to name a target and let the spell fizzle? Or if either I or my creatures are the only valid targets do I have to target myself?

My understanding is that when a spell is known or prepared via one of your class features, or if you cast it via a class feature, it's considered a "class spell" (sorcerer spell, cleric spell, etc.) for you. If you cast it via some method outside your class (items, etc.), it isn't considered a spell from your class.  For clarity, some class features care about whether or not a spell is a 'class' spell (emphasis mine):    Wild Magic Surge for Wild Magic sorcerers can only trigger "[...] immediately after you cast a sorcerer spell [...]". Overchannel for School of Evocation wizards can only be used "when you cast a wizard spell [...]" Empowered Evocation for School of Evocation wizards can also only be used on "[...] any wizard evocation spell you cast". Rod of the pact keeper gives a bonus "[...] to the saving throw DCs of your warlock spells".   Contrast with a feature like Blessed Healer for Life Domain clerics that just use the language of "When you cast a spell [...]", and you'll see why I believe there's an important distinction as to whether or not a spell instance is a 'class' spell.  However, comments on  made me question where my understanding of what makes a spell instance a 'class' spell comes from, and I'm not sure of a concise spot that explains it. What are the rules that govern what is or is not considered a class spell when cast?   Of particular concern is whether or not a spell is, in all instances, a class spell once you've obtained it from your class. For example, if you were a wizard that had magic missile both prepared and in your spellbook, would any instance of magic missile you cast be considered a wizard spell, even if it was cast by way of, say, a wand of magic missile?

I'm a little bit confused with the whole spell system and additions to them. If I pick for instance Tempest Domain Spell, are the spells additional to the other ones? (2 at level 1) So do that make it 3 spells? Does the domain add slots too?  And also, I've read about people choosing multiple domains, is that possible?
