## gmail – What is this "Google Magic", sometimes it marks it as important because of Google Magic?

When I looked at my emails, sometimes it said that I marked it as important, or sometimes it said that it was sent to me directly, and sometimes it was marked because of Google Magic. Does that deceive me or does it really exist.
An example of this saying this:

## dnd 5e – Does the Realten Realms setting count as "High Magic"?

### Traditionally, the Forgotten Realms is not quite "high magic".

Although the magic is somewhat banal in the Forgotten Realms, it is actually the basic level of magic in a D & D campaign. The Forgotten Realms is sometimes considered high fantasy, but not high magic by the standards of D & D. High magic means that magic is more common or more powerful than the norm; in 5th Forgotten Realms is The standard.

### What is the definition of a "high magic" campaign?

The basic rules of D & D 5e do not define "high magic" as a campaign descriptor, aside from DMG's magic element tables p.38, in which it means that magic elements are more common . Xanathar's guidep.126 also suggests that magic items are more readily available in high magic campaigns.

"High Magic" as campaign descriptor is otherwise not defined in D & D 5th. However, it was originally defined in previous editions of D & D and, to the extent that this term has an objective and measurable definition, it is reflected in these older editions.

The D & D 3.0 Dungeon Master Guide, p.164, defines high magic as following:

The casters and the magic treasures are twice as frequent as those presented in these rules, if not more. Most characters have a level or two wizard or wizard. Even a trader can be at least a first-level caster. Magic items are bought and sold in clearly identified stores just like any other merchandise. Spells are used to light houses, keep people warm and communicate. The function they perform is as commonplace as modern technology is in the real world.

The terms "high magic" and "low magic" were more commonly used in WotC D & D products after this point, and even the 3.5 DMG omits its definition.

In the preview of Warforged, Shifters, Changelings and Kalashtar in Your D & D Game (2005), Stephen Schubert states that Warforged could be trivial in a highly magical environment:

Because warforged are examples of magical creation at its peak, they are perfect for very magical games. However, they could also be ancient remnants of a bygone civilization recently discovered by adventurers.

In the interview with Cityscape (2006), Ari Marmell describes high magic as something quite beyond the usual paradigm:

In the same way, the book does take some time to approach some cities of high magic or other unusual cities. (For example, the notion of flying cities or planes is addressed in short.)

### Do the Forgotten Realms meet this definition of "high magic"?

No.

The magical level of kingdoms has been canonically described in D & D 3.0 Setting up the Forgotten Realms campaignp. 92, "Magic in Society":

Holders of Arcane magic, also known as Art, are rare in most Heartland societies. No more than one in a hundred people are likely to have wizarding or sorcerer skills.

The text goes on to explain that in the most concentrated places of magic, as among the high elves, the rate of arcane spellcasters is up to ten times higher, but that still represents about 10% of the population, which is significantly lower than D & D 3.0 & # 39; s formal definition.

The canonical transition cataclysms of the 4th and 5th reigns have probably further reduced the magic of the scenery. The Spellplague has weakened some objects and violently reduces the number of spellcasters:

Most permanent magic items, such as artifacts, were left intact at the end of the Spellplague, but charged magical items were either destroyed, deformed, or simply stopped working. …

The blue flames also infected the portals and planar gates, spreading further into Toril. Almost all parts of Faerûn were affected by the Spellplague and some areas were entirely eliminated, while others were created again. Thousands of spellcasters have been destroyed or gone insane due to the collapse of Weave after Mystra's death. In Cormyr, one-third of the wizards of the war were killed or made mad. Those who have survived have lost their ability to use arcane magic.

## 5th dnd – Can a non-magical "Detect Magic" type character capture magic when used in an antimagic field?

If you have a non-magic ability "Magic of meaning", eg. the Chuul, but you're inside a antimagic field, can you detect the magic (from a source that is out of the field)?

The magic meaning trait of chuul states:

Chuul feels magic at less than 120 feet at will. This trait works differently as the detect the magic spell but is not magic itself.

This means that this feature would not be canceled by a antimagic field.

Detect the magic himself has 2 parts, first "to feel the magic" and secondly to see his aura:

During all this time, you feel the presence of magic within 30 feet of you. If you feel magic in this way, you can use your action to see a weak aura around any creature or object visible in the area that is wearing magic, and you'll learn his magic school, if any.

The spell can penetrate most fences, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or earth.

Now, antimagic field (the spell) declares that:

This area is separated from the magical energy that permeates the multiverse. In the sphere, spells can not be cast, summoned creatures disappear, and even magic items become mundane.

Spells and other magical effects, except those created by an artifact or deity, are removed from the sphere and can not be protruded.

Will magic auras, which Detect Magic allows you to see, even reach you while you're in the field?

I could not really find a RAW or RAI definition of whether these auras count as a "magic effect," or whether it's essentially a non-magical energy emission that you can not normally see, and that the detection of magic simply expands. you aim the visual range to encompass it.

And the first part, that of feeling the magic in the first place, is left entirely to our imagination, but there must still be some kind of emanation that must reach your player, so the same question arises.

## calculation and analysis – Solve a four-dimensional constraint integration problem for a "simplex magic" probability

The equation (7) in the 2012 paper, "Complementarity reveals the entangled entanglement of two twisted photons" of B. C. Hiesmayr and W. Löffler for a state $$rho_d$$ in the "magic simplex" of Bell's states
$$begin {equation} rho_d = frac {q_4 (1- delta (d-3)) sum _ {z = 2} ^ {d-2} left ( sum_ {i = 0} ^ {d-1} P_ {i, z} right)} {d} + frac {q_2 sum _ {i = 1} ^ {d-1} P_ {i, 0}} {(d-1) (d + 1) } + frac {q_3 sum _ {i = 0} ^ {d-1} P_ {i, 1}} {d} + frac { left (- frac {q_1} {d ^ 2-d-1} – frac {q_2} {d + 1} – (d-3) q_4-q_3 + 1 right) text {IdentityMatrix} left[d^2right]} {d ^ 2} + frac {q_1 P_ {0,0}} {d ^ 2-d-1} end {equation}$$
yields for certain values ​​of the $$q_i$$& # 39; s, "for $$d = 3$$ the state of Horodecki to a parameter, the first entangled bound state ".

More generally, for the case $$d = 3$$, the constraint imposing that the partial transposition (obtained by transposing in place the nine $$3 times 3$$ blocks) of the density matrix $$rho_3$$ to be positive defined takes the form

``````constraint3 = q1> 0 && q2> 0 && q3> 0 && 4 q1 + 5 q2 + 20 q3 <20 && 512 q1 ^ 2 + 80 q1 (8-11 q2 + 4 q3) +25 (5 q2 ^ 2 + 16 q2 (2 + q3) +64 (-1 + q3) (1 + 2 q3)) <0
``````

The command

``````To integrate[Boole[constraint3], {q1,0,5}, {q2,0,4}, {q3,0,1}]/ (10/3)
``````

then, interestingly, gives Hilbert-Schmidt's "PPT probability" that the partial transposition of $$rho_3$$ is positive defined,

``````(1/13720) (- 4312 + 5145 [Pi] + 2240 Sqrt[7] ArcCos[11/(8 Sqrt[2])]- 5160 Sqrt[7] ArcSin[(5Sqrt[(5Sqrt[(5Sqrt[(5Sqrt[7]) / 16]- 6860 ArcTan[7] + 6280 Sqrt[7] ArcTan[(5Sqrt[(5Sqrt[(5Sqrt[(5Sqrt[7]) / 9])
``````

which is approximately 0.461554. (This result was published as a comment in my previous query https://quantumcomputing.stackexchange.com/posts/5943/edit.)

Now, I would like to solve in the same way the most formidable $$d = 4$$ problem. Then, the constraint (found by the application of the sharpness of the sixteen nested miners of the two $$rho_4$$ and its partial transposition $$rho_4 ^ {PT}$$) takes the form

``````                constraint4 = q1> 0 && q2> 0 && q3> 0 && q4> 0 && 5 q1 + 11 (q2 + 5 (q3 + q4)) <55 && 3375 q1 ^ 2 + 121 (7 q2 ^ 2 + 90 q2 ( 1 + q3-q4)) +3 q3-q4) (-1 + q3 + q4)) <330 q1 (19 q2-15 (1 + q3-q4)) && (45 q1 + 11 (15-7 q2-) 15 q3 + 45 q4)) (75 q1-11 (15 + q2-15 q3 + 45 q4)) <0
``````

Order application

``````To integrate[Boole[constraint4], {q3,0,1}, {q2,0,5}, {q1,0,11}, {q4,0,1}]/ (55/24)
``````

would then give the corresponding PPT probability of Hilbert-Schmidt. (The GenericCylindricalDecomposition command suggested classifying the four variables according to the 24 possible commands, but you can of course study the variations.)

Right now, by simply using the free form of WolframCloud, my various attempts to effect integration – according to either approach – have come to an end. In any case, the problem may be too formidable, far from it. (Maybe some variable transformations might be effective.)

Given these PPT probabilities, the next question that arises – of a nature that has never really been addressed in a meaningful way – is how probabilities are divided between "entangled" and "separable" states (cf. Fig. 3 of Hiesmayr / Löffler).

## dnd 3.5e – Does the "Do you get magic" gift allow a character to see characters hidden by magic?

One of the onehot campaign players I write chose the exploit Pierce the magic concealment (Complete Arcane, p.81), as DM I do not know how it would work in a meeting I'm planning.

The manual says:

Pierce the magic concealment

You ignore the missed chance provided by some magic effects.

Your fierce contempt for magic allows you to overlook missed opportunities granted by spells or abilities similar to spells such as darkness, blur, invisibility, fog obscuring, ghosts (see page 109) and the spells used to create hiding effects (as a hiding effect). magician using a permanent image to fill an illusory corridor of fire and smoke). In addition, facing a creature protected by a mirror image, you can immediately choose the real creature from among his creations. Your ability to ignore the loss of chance afforded by magical concealment does not allow you to ignore non-magical concealment (so you would still have a 20% chance of missing out against an invisible creature hidden in the fog, for example).

It does not say if a character with this feat can actually see an enemy for example under the effect of the spell Invisibility (Player's Manual, page 245).

I anticipate a meeting in which the evening will be invited by a sorcerer to dinner, an assassin under the effect of invisibility pretending to be an imitator. An invisible servant (Player's Manual, page 297) until the wizard sends him the signal to attack the group.

Does the character who has the Pierce the magic concealment Is it possible to see the killer, or at least have an advantage in noticing that he is not an invisible servant?
