Since advantage and disadvantage caused in a heavily obscured area cancel out, what effect does it have in combat?

The rules say that creatures in a heavily obscured area “effectively suffer from the blinded condition”.

The blinded condition states:

Attacks rolls against the creature have advantage, and the creature’s attack rolls have disadvantage.

So when the Darkness spell (to use one example) is cast, combatants gain advantage and disadvantage when attacking others who are also inside the area, which cancel out.

Since they then cancel each other out and attacks are made normally, what really changes?

What happens when Restrained creatures are removed from the area of effect of Entangle?

The victims of an Entangle spell are Restrained and cannot move themselves; but can be moved by others. I had always assumed that moving them out of the Area of Effect of the spell would free them; but a close reading of the spell now has me questioning this.

Grasping weeds and vines sprout from the ground in a 20-foot square starting from a point within range…A creature in the area when you cast the spell must succeed on a Strength saving throw or be restrained by the entangling plants until the spell ends. A creature restrained by the plants can use its action to make a Strength check against your spell save DC. On a success, it frees itself.

As written, there are only two things which explicitly end the restrained condition; the end of the spell and a successful strength check by the victim.

Contrast this with the Web spell.

On a failed save, the creature is restrained as long as it remains in the webs or until it breaks free.

There, a creature that leaves "the webs" (=VoE?) is explicitly free of restraint.

However, note that with Entangle, the "entangling plants" themselves are limited to the initial 20 foot square (not cube), and while there they "sprout from the ground". Under the 5e principle that there is no flavor text in spells, it could be that the vines can only Restrain one while they are connected to the ground, and leaving the area does not take the plants along.

Note that if the vines wrap around anything, it is only the feet and legs – a Restrained character cannot move themselves, but they can still attack and cast spells. Restrained does not mean Incapacitated.

So, do these plant restraints remain tightly coiled around one’s legs, keeping one restrained even if moved away from the original ground, or do the restraints fall away once the plants are ripped from the ground?

How does Spell Sniper effect spells that allow ranged spell attacks on subsequent rounds? [duplicate]

The spells Crown of Stars, Storm Sphere, and Wall of Light all allow you to make ranged attacks on subsequent rounds.

Wall of Light

Until the spell ends, you can use an action to launch a beam of radiance from the wall at one creature you can see within 60 feet of it. Make a ranged spell attack. On a hit, the target takes 4d8 radiant damage.

Storm Sphere

Until the spell ends, you can use a bonus action on each of your turns to cause a bolt of lightning to leap from the center of the sphere toward one creature you choose within 60 feet of the center. Make a ranged spell attack. You have advantage on the attack roll if the target is in the sphere. On a hit, the target takes 4d6 lightning damage.

Crown of Stars

You can use a bonus action to send one of the motes streaking toward one creature or object within 120 feet of you. When you do so, make a ranged spell attack. On a hit, the target takes 4d12 radiant damage.

The spell sniper feat says:

When you cast a spell that requires you to make an attack roll, the spell’s range is doubled.

To use all of the spells effects, you are required to make an attack roll. That is, they have functions that don’t work without a attack roll.

Is that reading correct, and if so which of the ranges in each spell are effected?

Unity “scrape away” effect

I am trying to create a effect similar to what is described here How can I let players "scrape away" one texture to reveal another?

I have tried working through this but am confused and hoping someone could provide more info or if there is another way of doing it. Essentially I need to use a laser effect to "burn" or scrape paint from a door to reveal a layer below. Or any object.

Does Green Flame Blade and Sweeping Attack combo cause the bonus effect of GFB to hit again?

So I was theory crafting and I came across the combination of Green-Flame Blade with the Battlemaster Fighter’s Sweeping Attack maneuver. I understand that just fine. What I am unclear on is this:

I cast GFB and hit target. Then I activate SA to roll Superiority Dice to hit a second foe for the Dice’s damage (If the original attack would hit the second foe’s AC).

So I end up with one melee weapon attack that hits two different foes with special effects added to the attack. So it should look like this correct?

Weapon damage + GFB damage. GFB Jump damage to second target. Superiority Dice damage + GFB damage (because it is still the same attack correct?). GFB Jump damage to another target (possibly the original) ((because it states that this happens on a hit with an attack?)).

Do readied spells take effect?

The rules for readying spells says the following:

When you ready a spell, you cast it as normal but hold its energy, which you release with your reaction when the trigger occurs.

I saw this argument on reddit today:

The rules say you cast the spell as normal, so the spell takes effect immediately. I have no idea what the energy stuff is about, but it says you cast the spell as normal.

It seems to me like the intention is for the spell to only take effect when the trigger occurs and the caster chooses to activate the spell. I don’t have any doubt that’s how it’s supposed to work.

However I think the reddit user has a point, the whole "energy" thing is a bit ill-defined. Is there a concrete text in the rules that proves that "holding back energy and releasing it" change the timing of a spell being cast?

What happens to a spell cast by a target affected by the delayed effect of the Slow spell when he saves?

Part of the description of the Slow spell says:

If the creature attempts to cast a spell with a casting time of 1 action, roll a d20. On an 11 or higher, the spell doesn’t take effect until the creature’s next turn, and the creature must use its action on that turn to complete the spell. If it can’t, the spell is wasted.

The affected spellcaster casts a spell and is hindered by the Slow spell so that his spell does not go off until his next turn, but he saves against the Slow spell at the end of his turn.

Effect of Firefox’s “Responsive Design Mode” on the browser’s fingerprint

Today I switched ON the "Responsive Design Mode" under the "Web Developer" Section of the Firefox menu, and from the dropdown menu selected "iPhone X/XS iOS 12".

So now every webpage I visited was being sent the request that the screen size of my device was "375×812".

My question is that, can this method enhance my protection against browser fingerprinting(assuming I also take some other precautions)? Because the websites now wouldn’t be able to know my original aspect ratio/screen resolution, and above 2 iPhones are quite common too(I am using a laptop).

I earlier tried to scale the Firefox window to nearly the aspect ratio of a mobile phone, but that didn’t make any differnce at all.

Note:

(i) In the context of this question my adversaries are only the companies and their websites,and not the Governments & ISPs.

(ii) I am just asking about the effect of this method on my browser’s fingerprint, that is, whether it will increase or decrease the fingerprint. Be advised: I am not using this as the only method.

(iii) Firefox version: 78.0.2

(iv) OS: some linux distro.
