Can one force-feed an opponent a potion in combat?

Question

Is there a check by which a combatant can force-feed an unwilling target a potion?

The question stems from several magic items, including the Potion of Diminution and Potion of Poison. I am seeking to develop an expanded list of potions for the Unearthed Arcana Artificer class and the ability to affect an enemy with potions such as these would be grounds for a much higher spell slot to Infuse than if it was restricted to willing targets (or misled, in the case of Poison).

This question is specifically in reference to conscious opponents, enemies who can resist the attempt.

Answer 1

The only thing stopping you is the DM.

You might need to force it's mouth open, Strength vs Strength, or torture (oooooh evil acts!) to make it scream, or maybe even beat a Constitution check (gag reflex throwing the potion up) in order to make it drink.

But really your job is simple: describe what you want to do, roll against whatever the DM wants. If your DM is floundering, make your case as to why you're doing it, and what would make sense logically to you.

If you are the DM, go with whatever makes sense. There's no hard and fast rule on this, so it's going to be an improvised situation.

Oh, incidentally, there's no crafting table either. Which means when you craft your potions, consider the 3 methods of attack; Ingested, Contact and Inhaled.

Who's to say you can't turn that poison potion into a contact (attack roll to administer) or inhaled (Con save) version?

The RAW has No specific "check" to force-feed an enemy

There is no specific Check to "Force-Feed" a target in 5e. That's typically left-up to the DM, as there are few-to-no creatures in 5e which specifically force-feed their targets (as opposed to implanting eggs in them like Slaadi, because those rely on Claw attacks).

However, it's not hard to envision the process.

It's not easy to force-feed someone

Force-feeding itself is a difficult task, whether it be poison to an enemy or antidote to a spy who is trying to poison themselves. Typically, it requires the target being Restrained, Grappeled, or Incapacitated in some way.

Because your question states:

This question is specifically in reference to conscious opponents, enemies who can resist the attempt.

I will primarily discuss Restrained and Grappeled opponents rather than Incapacitated opponents for the purpose of "resisting", though I will mention Incapacitation as-well.

To outline the process of Force-feeding, the first check should be to Restrain or Grapple them if they are not, because it is almost entirely impossible to force-feed someone who is capable of moving away. This can be either done by the person performing the force-feeding or one of their Party-Members. The next check would be a Strength Check to force their mouth open or a Dexterity check to "feed" them while their mouth is open. Finally, whatever Save is required of the Poison or substance being fed is required to resist it. If there is no stated "Save", I would rule it as having at least a DC 10-15 (based-on the substance) Constitution Save to resist the Poison, because the creature does not want the effect, having no effect on a successful save.

If the Target was Incapacitated as opposed to Grappled or Restrained, the Dexterity or Strength check would be made with Advantage.

So, in-summary:

1. Grapple, Restrain, or Incapacitate the Target
2. Strength or Dexterity Check to force the substance into the Target
3. (Target) Constitution Save to determine the effects of the substance.

All-in-all, it's easier to Charm the target into drinking a "new beverage" instead of trying to force-feed them.

Answer 3

A quote for you:

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. (PHB, p 153)

Administering a potion generally implies doing it to someone else. It implies a lack of opposition, but nothing prohibits doing it to an unconscious foe.

Answer 4

What is Administering

Administering a potion to a willing party is much different than force-feeding an enemy.

Administering means (dictionary definition):

• dispense or apply (a remedy or drug).
• give help or service.

Force-feeding an unwilling person a potion, I'd argue, is a lot more involved than "administering" a potion.

Rules About Forcing a Potion

There aren't any rules concerning this, but D&D rules don't aim to solve every edge case. How to handle improvised actions, which are a lot of good D&D, is up to the DM.

For DMs making a reasonable ruling for this sort of thing, consider what it is like in reality, and what rules you already have.

Having a child and a dog who sometimes need to take medicine they don't want to take, I can tell you that in reality, it is more difficult and time-consuming than it seems.

There are rules for grappling, which seems like a first step or similar action to forcing someone's mouth open. I could see some kind of save from the person to see if they could spit the liquid out. So, I likely would have ruled the same way you did.

Answer 5

Once, but not twice

"A group of lesser combatant overwhelming a greater opponent and force-feeding him a potion and defeating him" sounds like a great and memorable scene, but only the first time it happens. After that it just get silly.

Combat is to hectic and prying someones mouth open and then pouring the entire content of the potion into them would require quite a lot of time and concentration. In my estimation it is also a task that would require two maybe three persons to achieve; One to grapple the victim, One to pry the victims mouth open and One to pour the liquid and make sure not to much is spilled.

While the group is busy doing this I would give them all kinds of penalties. Make them easier to hit since they are no longer dodging, give the opponent attacks of opportunity and so on.
