Can I enchant a necklace with the equivalent of a healing potion? (DnD 5e)

I know nothing of magic items really, especially custom ones, so I’m just going to describe an ideal scenario and I’d love some help in how something like it could be achieved, please! Am looking for some way to enchant a necklace with the ability to give some HP to the wearer. In an ideal world this would be triggered if the wearer hits 0HP, and would be rechargeable in some way. My player is not a spell caster, so I would be looking for a merchant or someone in town who could do this for her, if you have any advice on how much this might cost, up front and for each recharge or something. (For flavour reasons, she already has a specific necklace she’d like to enchant) If anything like this is possible, I’d love some help! Thanks!

How much does a “Potion of cure light wounds” heal?

According to the documentation, a potion of cure light wounds points to the spell “cure light wounds”. Now, the spell has some info about healing:

cures 1d8 points of damage +1 point per caster level (maximum +5)

But the caster level is just for the cleric who casts the spell. So what would be the correct amount of healing with the potion alone? just 1d8? or 1d8+5?

I could not find any clearer documentation for the potion yet.

Can an unconscious person drink a potion?

PHB 153 reads:

Potion of Healing. A character who drinks the magical red fluid in this vial regains 2d4 + 2 hit points. Drinking or administering a potion takes an action.

By my interpretation, this means that while the rules are flexible in regards to who has to spend the action, they are inflexible in that a character must still actually drink the potion. In other words, any character can administer a potion to save someone else’s action, but their target must be conscious and able to drink.

I know part of a DM’s job is to apply common sense to my rulings, and common sense tells me that an unconscious person is more likely to choke to death than to swallow 4oz of liquid.

A few of my players disagree. Who’s right in this situation?

Do the effects of a Potion of Speed or Potion of Heroism disappear if the character becomes unconscious?

Pretty much as the title states.

If a player is under the effect of a potion of speed

When you drink this potion, you gain the Effect of the haste spell for 1 minute (no Concentration required). The potion’s yellow fluid is streaked with black and swirls on its own.

or a Potion of Heroism

For 1 hour after drinking it, you gain 10 Temporary Hit Points that last for 1 hour. For the same Duration, you are under the Effect of the bless spell (no Concentration required). This blue potion bubbles and steams as if boiling.

Do those effects wear off if the play is reduced to 0 hit points and becomes unconscious before the 1 hour duration?

How many turns does it take for an unseen servant to pass a healing potion in combat?

Unseen servant reads:

Once on each of your turns as a bonus action, you can mentally command the servant to move up to 15 feet and interact with an object. The servant can perform simple tasks that a human servant could do, such as fetching things, cleaning, mending, folding clothes, lighting fires, serving food, and pouring wine. Once you give the command, the servant performs the task to the best of its ability until it completes the task, then waits for your next command.

Assume I used my bonus action to command it to give the healing potion in my pocket to another character, and that it is within reach when I do. It would take a player one turn to complete the task. A free item interaction to draw the potion, then movement, followed by an action to safely pass it over. But the unseen servant seems to be solely capable of movement then a single item interaction.

How many turns would it take for it to perform this task? And if two or more are necessary what is the order of operations? Can it move after interacting with an object?

Does a potion of healing hurt undead?

The other night one of my players thought it a good idea to throw a potion of healing at the undead skeletal mage. Her idea was that the potion would harm undead. A creative idea and I said go ahead, but I really didn’t know what to do.

Luckily she rolled a one and the potion smashed against the wall behind the skeletal mage. I had the mage take one of his bony fingers, scrape some of the potion off the wall, and apply it to his mouth saying he was healed 1 hp point.

My thoughts were healing potions are not radiant, therefore it would not hurt him. Was I wrong in my jugement?

Thanks 🙂

Would it harm game balance to allow the Haste action to be used to drink a potion?

RAW, Haste specifies:

[The target] gains an additional action on each of its turns. That action can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action.

And it has already been stablished that “Use an object” is not valid to use a magic item which to my understanding includes drinking a potion.

So my question is, would it break balance much to actually disregard that and allow the drinking of a potion as one of the actions granted by Haste?

How much does a potion weigh?

I’m considering having my players find a big cache of alchemical items as part of an upcoming adventure. I feel like dozens of bottles of liquid should weigh something, but I don’t see a weight listed anywhere.

Do any potions, alchemical items, or consumables have listed weights anywhere?

If not, have you given these things weight in your games? How much? Any problems?

Our game attempts to be fairly realistic, so information on how much a small glass vial actually weighs might be useful as well. I don’t have any small glass vials sitting around.

What happens when you double the numerical effect of a potion of giant strength?

Potions of Giant Strength give the drinker a new numerical value to their Strength score.

The DMG provides a Potion Miscibility Variant table, one of the effects being :

91-99 The numerical effects and duration of one potion are doubled.

Now say that, with the DM’s approval, a player character mixes a potion of, say, Cloud giant strength (27) with another one and rolls that effect on the above Table, and then drinks that special mixed potion. What would their Strength score be ? 26, 30, or 54 ?
