RAW/RAI Potions/Magic Items In Anti-Magic Field?

I am thinking about how to use a beholder as a DM.  Have not used one in a 5.5 session yet, just in a white box.  They have an anti-magic field.

Question:

1. Do new potions work in an anti-magic field?

2. Are potion effects cancelled by an anti-magic field?

3. If they are cancelled, would a healing potion used recently cause an anti-magic field to drain HP based on the heal and the  yo-yo back afterward?

4. Are some potions magical and some non-magical? (herbs/medicine vs actual arcane magic)

5. Is there a way to use something like counterspell to cancel out anti-magic fields for the sake of potions? (throwing spaghetti at the wall but I’m curious)

6. Are magic items completely dumbed down by anti-magic fields? Or do they keep some features but not others?

7. If a magic weapon has an extra attack built in, is the extra attack considered magical or is it simply a feature of the weapon’s quality and isn’t affected?

8. Is there a way to create a magic item or a potion that is not impacted by anti-magic field?  Could such a thing exists RAW?

That’s it.  Thank you for your time and wisdom.

1. Potions are magic items and "Magical properties of magic items don’t work inside the aura or on anything inside it."
2. See #1.
3. Healing is an instantaneous effect, so while the potion cannot be used while in an antimagic field, drinking a potion and entering an antimagic effect has no special effect.
4. RAW, all potions are magic items. The DM may choose to rule otherwise.
5. There aren't any spells in 5.5e that can remove an antimagic field.
6. Magic items keep their mundane properties, if any (mostly relevant to weapons and armor).
7. Effects built into magic items are magical effects and will be surprised.
8. Effects created by an artifact are not suppressed within an antimagic field. It is not clear whether this allows using the item.

The main weakness of the beholder's antimagic ray is... all of the beholder's other rays are magical effects and thus cannot be used on targets within the main eye's field.

No, but Wish can grant immunity to it for 8 hours if you cast it outside of the field.

I would say that, at the very least, the inability to take the Magic action will restrict some of an Artefact's properties. Any other activated effects may or may not be prevented.

There's a related question in the SAC about Antimagic Field  and the instantaneous effects mentioned by Pantagruel666:

Can you use Dispel Magic on the creations of a spell like Animate Dead or affect those creations with Antimagic Field?

Whenever you wonder whether a spell’s effects can be dispelled or suspended, you need to answer one question: is the spell’s duration instantaneous? If the answer is yes, there is nothing to dispel or suspend. Here’s why: the effects of an instantaneous spell are brought into being by magic, but the effects aren’t sustained by magic. The magic flares for a split second and then vanishes. For example, the instantaneous spell Animate Dead harnesses magical energy to turn a corpse or a pile of bones into an Undead creature. That necromantic magic is present for an instant and is then gone. The resulting creature now exists without the magic’s help. Casting Dispel Magic on the creature can’t end its mockery of life, and the Undead can wander into an Antimagic Field with no adverse effect.

Another example: Cure Wounds instantaneously restores Hit Points to a creature. Because the spell’s duration is instantaneous, the restoration can’t be later dispelled. And you don’t suddenly lose Hit Points if you step into an Antimagic Field!

In contrast, a spell like Conjure Woodland Beings has a non-instantaneous duration, which means its effect can be ended by Dispel Magic and temporarily disappears within an Antimagic Field.

Btw, not sure if it's helpful for you packman767, but I think the following thread about Antimagic Field is an interesting read, at least: Does Spellfire Sorcery's Class Features work inside Antimagic Fields?

 Most of this makes sense.  The part I am wondering about is if a potion that is already drunk is still considered an item that loses its properties.  Because for it to lose its properties it would have to exist.  But the potion no longer exists.

The effect of a healing potion is instantaneous, but so is a potion of giant strength.  It doesn’t require concentration.  So I am wondering if, like a PoH, there are other potions that would persist because they are simply a stat boost and not a spell effect?

Specifically, I see why an undrunk potion would lose its effect, but a potion that no longer exists cannot be impacted….  it’s a weird semantics issue.  When a character drinks a potion, like healing, is their body altered in order to have a special effect?

Anyway that’s where I see the nuance here.  But I might be reading too much into it.

 Well shoot if a character is using wish I’d probably just expect them to insta-kill the beholder somehow.  Using wish to make a potion work seem like a huge waste…. though….. hypothetically….. you could alter reality to change the powers of the Beholder to simply not have an anti-magic field…. lol man 🧀

 Cool… thank you!

 That's not what instantaneous means. Instantaneous effects in 5e are effects that have no duration -- they make some change to the world and then they're done. A potion of giant strength has a duration, and thus there is a magical effect (created by the potion) on the character, which can be suppressed.

A beholder is CR 13. A Ring of 3 Wishes or a Scroll of Wish are Legendary, which would fall in the level 11+ recommended list of magic items. Use it on one of the casters and confused the Beholder when they keep casting spells right in front of the Beholder while the cone protects the caster from the Beholder's rays.

There may be other solutions, but they'd still have to bypass the Beholder's legendary resistance and the antimagic field.
