Your players are right. An unconscious character can consume a potion administered by another player.
This ruling is held up by the Sage Advice Compendium (p. 21):
Can potions be administered to unconscious characters as an action?
Yes, you can administer a potion to someone else as an action (DMG, 139).
As with all things, it's perfectly allowable to ...
The character can spend HD after an hour. (Now confirmed by Jeremy Crawford; as always, take twitter with a grain of salt.)
Just read the "Resting" rules.
A short rest is a period of downtime, at least 1 hour long, during which a character does nothing more strenuous than eating, drinking, reading, and tending to wounds. (PHB p.186, "Short Rest")
No such rule exists.
There is simply no rule that says healing a creature with 0 hit points only counts as 1 hit point. The rules do say this:
The best way to save a creature with 0 hit points is to heal it.
A creature receives full healing from any healing spell while unconscious and at 0 hit points, and they immediately become conscious again:
Yes. RAW, Evasion means a character only takes half damage, even when unconscious.
The relevant part of Evasion text, that you've quoted says:
When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail. (SRD p. ...
Unfortunately, as awesome as this sounds, by the rules, it doesn't work. Hellish Rebuke is a reaction that you take
in response to being damaged
Not "in response to being hit", or "in response to being attacked". You actually have to take damage to use it.
Whenever a creature takes damage, that damage is
subtracted from its hit points.
You haven't ...
From the Polymorph spell description:
This spell can't affect a target that has 0 hit points.
Of note: this caveat was added in the Player's Handbook Errata, as pointed out by Thyzer, after the original printing. Some PHBs may not contain this text, but it nonetheless is the intended rules.
Other spells with polymorphing effects don't work either:
Yes. This is a correct interpretation.
As Tuggy points out, without calling it such, this is the coup de grace mechanic in 5e.
If you're unconscious and you get hit from 5' away it's a critical hit, being a critical hit means it's two failed death saves (And a chance to kill you outright if it does your max hp damage).
This seems very much to be the ...
No, as far as the rules are concerned, being knocked out does not affect whether you gain experience. The DMG has this to say about experience on page 260:
Each monster has an XP value based on its challenge rating. When adventurers defeat one or more monsters-typically by killing, routing, or capturing them-they divide the total XP value of the monsters ...
Since the goblin is sleeping, you could rule that the rogue surprises the goblin and gets a free round of actions before the goblin can react. In this case initiative is rolled as usual, but only the rogue gets to act on the first round (so if the goblin wins initiative, it still gets to act only after the rogue completes their turn).
Even if you don't rule ...
If you succeed on a Death Saving Throws 3 times, you don't recover any hitpoints. Instead, you become stable:
A stable creature doesn’t make death saving throws, even though it has 0 hit points, but it does remain unconscious.
The creature stops being stable, and must
start making death saving throws again, if it takes any
A stable ...
Disguise Self does not end when you are incapacitated
According to the rules on spell duration in the Player's Handbook
A spell's duration is the length of time the spell persists. A duration can be expressed in rounds, minutes, hours, or even years. Some spells specify that their effects last until the spells are dispelled or destroyed.
There is no ...
By RAW, you may not be able to administer a goodberry - by RAI, you most certainly can
A very strict RAW reading would conclude that in order to gain the benefit of a goodberry, the consuming character must be able to use their action to consume it. However, as it happens, this question has been asked of Jeremy Crawford via twitter (whose tweets were, at the ...
This is an exception to the general rule, the PC takes one death save failure.
You've accurately quoted the relevant general rules.
RAW two death save failures would normally be taken by a PC from an attacker within 5 feet while that PC is unconscious (as correctly reasoned in the question).
So, if no one successfully intervenes before the PC's next turn (...
The rules that you've quoted are pretty clear. You gain advantage when attacking unconscious creatures, and you gain disadvantage when attacking prone creatures from further than 5 feet away. If you have both advantage and disadvantage — you're attacking an unconscious creature from further than 5 feet away — you get neither, instead.
Yes, unconscious creatures still roll saving throws.
"Automatically fails Strength and Dexterity saving throws" implies that other saving throws do not automatically fail. The phrasing would be different if they intended all saves to automatically fail.
PHB p.179 states "A saving throw—also called a save—represents an attempt to resist a spell, a trap, a ...
A fireball or a similar AoE spell would not crit
The Unconscious condition does state that (from the SRD p. 359, emphasis mine):
Any attack that hits the creature is a critical hit if the attacker is within 5 feet of the creature.
An "attack" is a well-defined term in the 5e rules that is different from the basic English meaning of what an attack is. ...
Don't get knocked unconscious
While this is not the answer you're looking for, it's about the best one we can give. An unconscious character can, by the plain English definition of the word, not act. Both in the reality of the game world as well as the rules, that not bleeding out is the only thing your character can do.
If your character keeps getting ...
Jeremy Crawford gives an unofficial ruling here: Can you take a unconscious target with you using dimension door?
Only a willing creature can travel with you via dimension door. You can't give consent when you're unconscious.
Sorry, but No
The Key Word here is Attack. Attacks as defined in the PHB are D20 rolls against AC.
From PHB, 194
If there’s ever any question whether something you’re doing counts as an attack, the rule is simple: if you’re making an attack roll, you’re making an attack.
Critical Hits are defined on page 194 (emphasis mine),
If the d20 roll for an attack ...
The entry for Death Saving Throw says:
Whenever you start your turn with 0 hit points....
So this just means that you make the throw at the beginning of your turn. However, nowhere in the description does it say that it requires any kind of action to make the save.
A saving throw is an instant response to a harmful effect and is almost never done by ...
You would not fail a death saving throw from taking damage while the ward is up.
The rules for Damage at 0 Hit Points say (PHB, pg. 197):
If you take any damage while you have 0 hit points, you suffer a death saving throw failure.
If you have your Arcane Ward (PHB, pg. 115) up while unconscious and are attacked, then:
Whenever you take damage, the ward ...
This spell sends creatures into a magical slumber. Roll 5d8; the total is how many hit points of creatures this spell can affect. 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, each ...
There is no current rule that spell effects end when a caster is unconscious or dies unless they are specifically concentration spells.
Thus, since Find Familiar is not a concentration spell, it's perfectly reasonable to assume that the familiar stays and is unaffected by the fact that his wizard is unconscious (or dead).
And in fact, the ...
Not-Unconscious does not necessarily mean awake and aware.
Sometimes the game just expects us to understand certain terms without giving explicit rules text about what they mean. Famously, 5e doesn't specify a 'dead' condition or give any rules about what it means to be dead. So there is a precedent for the game having certain game concepts left to the ...
Yes. This is implied by the rules on death saving throws (PHB p.197), which state in part (emphasis added):
If you take any damage while you have 0 hit points, you suffer a death saving throw failure.
Note that damage while you are at 0 hit points doesn't reduce your hit points, though:
A creature's current hit points (usually just called hit points) ...
You can't treat the time you spend unconscious as a short rest.
A short rest is a period of downtime, at least 1 hour long, during which a character does nothing more strenuous than eating, drinking, reading, and tending to wounds.
There's a big difference between that and an hour spent unconscious because you almost died. I suspect that as far ...
You are definitely Poisoned
As PJRZ pointed out, failing the saving throw by 5 or more is an example of failing the saving throw. As such, you will both be unconscious (because you failed the save by more than 5), and poisoned (because you failed the saving throw at all).
It is very reasonable for you to ask why some other game features would include the ...
The answer to this is the combination of a few different rules, most which are found in the Player's Handbook ("PHB"), with a few extra notes found on page 77 of Xanathar's Guide to Everything ("XGE"), because these sort of questions did come up after the initial rules release.
First off, XGE makes its clear that when you're asleep, you have the unconscious ...
In my PHB the full suffocation rule is (emphasis mine):
A creature can hold its breath for a number of minutes equal to 1 + its Constitution modifier (minimum of 30 seconds).
When a creature runs out of breath or is choking, it can survive for a number of rounds equal to its Constitution modifier (minimum 1 round).
At the start of its next turn, it drops to ...
This is a slightly foggy area...but thankfully, Jeremy Crawford (official voice of rules for WotC) has weighed in on this in several (indirect) ways...
