Are undead and creatures immune to charm excluded from the HP count of Sleep?

From the spell description:

Sleep (…) Creatures within 20 feet of a point you choose within range are affected in ascending order of their current hit points (ignoring unconscious creatures). Starting with the creature that has the lowest current hit points,(…) Subtract each creature’s hit points from the total before moving on to the creature with the next lowest hit points. A creature’s hit points must be equal to or less than the remaining total for that creature to be affected. Undead and creatures immune to being charmed aren’t affected by this spell. (PH p.276)

Now, to build the ascending order of their current hitpoints, the spell instructs to count everyone in area of effect, but only ignore unconscous creatures. Then later on it says that Undead and creatures immune to being charmed aren’t affected.

Are those two latter kinds of creatures excluded from the roll of current HP by default? Following the “if they were it would say so” philosophy of Sage Advice, it doesn’t seem so to me.

Can a Succubus use its Charm action to make my undead minion attack me?

I animated a corpse (into a zombie) using the animate dead spell. During a fight with a succubus, the succubus tried to charm the zombie using its Charm ability:

One humanoid the fiend can see within 30 feet of it must succeed on a DC 15 Wisdom saving throw or be magically charmed for 1 day. The charmed target obeys the fiend’s verbal or telepathic commands. If the target suffers any harm or receives a suicidal command, it can repeat the saving throw, ending the effect on a success. If the target successfully saves against the effect, or if the effect on it ends, the target is immune to this fiend’s Charm for the next 24 hours.

The zombie is not immune to being charmed according to its stat block – but the animate dead spell says that I command the undead how to act.

Can the zombie be charmed into fighting me? In general, can creatures you command (familiars, summoned, animated) be charmed into fighting their master?

Does an Iron Flask (5e) work on a creature that is immune to Charm?

The Iron Flask states, “You can use an action to remove the flask’s stopper and release the creature the flask contains. The creature is friendly to you and your companions for 1 hour and obeys your commands for that Duration. If you give no commands or give it a Command that is likely to result in its death, it defends itself but otherwise takes no Actions. At the end of the Duration, the creature acts in accordance with its normal disposition and Alignment.”

Now my issue with this comes from the following incident that just occurred in my past session for Baldur’s Gate: Descent into Avernus. The players traversed the Scab prior to entering the Bleeding Citadel to find the Iron Flask amongst the deceased Night Hag’s obejects in her lair. They released the Fiendish flesh golem and killed it due to it not being their’s and attacked them so says the module. They still held onto it after the wizard identified it and realized its potential for demons if anything. So they eventually came across the diggers trying to dig out the Crokek’toeck. They killed them and reached the beast themselves to capture it in the Iron Flask instead. The bit I’m concerned with is they intend to use the creature as a trump card and have it serve them in battle for the hour use.

What I don’t understand is that the item doesn’t explicitly state that this is a charm on the creature to force its friendly position towards the party and adhere to their commands. The crokek’toeck has immunity to charm and confuses me as I presume the Iron Flask technically charms said captured entities to obey their temporary master(s). Due to the fact the item neglects to state this; do I proceed with the crokek’toeck being immune to the friendly nature once it pops out and proceeds to flee, attack, etc the party, or is this Flask meant to override that immunity and it works as they think it would, therefore obeying the party? I’m seeking a logical answer prior to flavored suggestions.

Is Charm Person obvious?

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′ away? From across a crowded room?

I’m specifically interested in an answer based on the rules as written, although interpretation and individual opinion is not unwelcome.

Charm person and why did this happen?

Hello i am fairly new to DnD however i have years of roleplay experience. Last night i attempted to charm a shopkeep old lady and the dm didn’t tell me iff i was successfull or failed he seems to do this with everything. Anyway having read the description of charm person and then reading several views on it by others it seems the common consensus if the nps pass’s the save and is not charmed that nothing should happen however what happened is this. The dm toled me the lady’s eyes started to glow slightly and to tell her what to do and so i asked her to give me some potions. I understood it as though if her eyes changed then yes she was charmed apparently this was not the case and she pulled a crossbow out on me instead so i left the shop. I really think i’ve been cheated here but i want your guys opinions as i’m unsure wether i need to talk to the gm or not like i said the common consensus i found is that if an npc is not charmed then nothing at all should happen untill the spell ends which is says they know they are charmed but they have to have been charmed in the first place to know this.

Does Charm Person break if the charmed person’s minions are attacked?

I’m trying to clarify with my players what is the effect of charm person on a very particular situation:

  1. Combat starts, player engage some zombies in battle and kill one of them via arrows.
  2. Fighter goes into the room and discovers a Necromancer and some zombie minions under its control.
  3. Druid wants to cast Charm Person spell on the Necromancer.

Assuming the necromancer fails the save, I’m having doubts about ruling how it will work.

According to answers to this question, charm person would only protect the druid, allies would still be attacked.

But the doubt here is about the part that says:

If it fails the saving throw, it is charmed by you until the spell ends or until you or your companions do anything harmful to it.

If anyone attacks the necromancer’s zombies, would that be regarded as “doing something harmful to” the necromancer? Or would it not break the spell because the attack is directed at one of his minions and not the necromancer himself?

Additionally, since the Druid has already attacked one of the minions, would the charm spell even work?

What can break a Vampire’s Charm besides Greater Restoration?

Our party faced a vampire. The charm of a vampire lasts 24 hours. He began charming our party one-by-one. As each character was charmed, we seemed to have nothing to reverse it. About the only thing that seemed to save us was the use of magical darkness so we couldn’t see it – but it had True Sight so its attacks were at Advantage. It was close to a TPK.

We noticed Jeremy Crawford also clarified that Dispel Magic doesn’t work.

Is there anything a party can do to break a Vampire’s Charm besides Greater Restoration?

Can a dryad charm a demon?

I have a concept that I want to use of a dryad soothing a demon, which shall be a demon’s past as their first step to redemption. So is there any way a demon/fiend be charmed by a dryad, if this could happen in the rules. If not is there a way to get around that problem? The fiend is a yochlol, which can’t return to their original plane, and is having an angry fit about it in a forest and destroying the forest with what they touch.

“Instinctive charm” timing question: can I use it after seeing the die roll?

Multiple abilities can be used “after seeing the roll, but before knowing whether it hits or misses” (examples: Cutting Words and Combat Inspiration).

However, in the case of the Enchantment Wizard’s level 6 ability Instinctive Charm, the text says that “you use this feature before knowing whether the attack hits or misses”. There is no mention of “seeing the roll”.

Do I get to see the attack roll before using Instinctive Charm?

Assuming I do get to see the roll and it is a critical hit (natural 20), can I still get to use Instinctive Charm? Or do I “know” the attack hits because it is a critical, and hence can’t use the ability?

Can a Vampire charm a blind person?

The wording of the Vampire’s charm action has me a bit confused on whether a blind person either gets no saving throw from it or can’t be charmed at all like this.

Here is the exact description:

Charm: The Vampire targets one humanoid it can see within 30 ft. of it. If the target can see the Vampire, the target must succeed on a DC 17 wisdom saving throw against this magic or be charmed by the Vampire.

Of course, this question is also relevant in case the Vampire is invisible or otherwise hidden in plain sight from a target with normal eyesight.
