dnd 5th – If an object or creature falls on a monster, how much damage does each one suffer?

If a character who was under the effect of a growth potion (double height and 8 times his weight) and weighed 2400 pounds. could use Door of dimension To teleport 400 feet or more into the air, directly over a monster of enormous size, and to have fallen, how much damage would the falling creature and the monster suffer?

I guess both would take the maximum of 20d6 for the fall of more than 200 feet, but is there an estimate of the extra damage for the falling creature's size?

According to the splat calculator, at 500 feet, you would fall to 196 km / h and you would spend 1.6 million joules of energy, the equivalent of more than 3,000 medium-sized cars hitting an object at 60 km / h.

2,400 Barbarian pounds falling to 500 feet is like dropping a mid-sized Toyota Carola from a 50-story building on a monster – it should do some damage.

Are there industry standards or specifications regarding the resistance of image sensors to the damage caused by intense light?

The standard closest to a standard that I could find came from looking for filters in the front of the lens for solar photography, ie, say filters for use with telescopes (or telephoto lenses) specially designed to take pictures of the sun in white light.

For visual solar observation, the standard is ND5.0. Baader Planetarium also offers an ND3.8 version for use in high magnification (NON visual) imaging, and the Wikipedia entry for neutral density filters contains the following note:

Note: ND 3.8 is the correct value for exposure to solar CCD without risk of electronic damage.

But do not have a quote to explain where the number comes from.

On the other hand, there is a clear conflict between this and the daily experience with non-SLR digital cameras. It is not unusual to have the sun in the plane – either intentionally or during framing – and yet we do not have any traces burned through the sensor.

Part of the explanation may be due to the fact that mainstream cameras have integrated infrared blocking filters for color balance (unlike many astronomical CCDs). Another
a part can be that many point cameras use relatively small lenses – so as not to capture as much heat and light as a telescope,
which usually have lenses or mirrors several inches in diameter.

In addition, with conventional photography, at least for freehand shooting, you usually take a few seconds at a time, often moving as you frame the shot – so you normally not much time for the heat to increase. If you compare this with solar imaging, where you normally follow the sun for several minutes (or sometimes a few hours), with a much larger lens / mirror (and thus capturing more light / heat), you can see why a filter becomes more important.

With a total solar eclipse in the United States, it is probably worthwhile to add a safety warning regarding visual filters. You only have one eye, so do not take chances – use only filters specifically designed for solar use. Do not try to improvise from exposed films, CDs or others. Visual performance is not a safe guide to performance at invisible IR / UV wavelengths. The appropriate sunscreens are relatively inexpensive – a few dollars for a portable device that you can look at with the naked eye,
or $ 20 to $ 30 for a solar filter film sheet, or you can get predefined filters (the ND5.0 visual quality filters are also suitable for photography).

and as specified by Wikipedia's ND filter entry:

Note: ND 5.0 ​​is the minimum required for direct solar observation in the eyes without retinal injury. An additional check must be made for the particular filter used, checking on the spectrogram that the UV and IR values ​​are also attenuated with the same value.

Specially designed sunscreens are safe. Others are unknown and are not worth risking your sight.

sensor – burnout LIDAR; standards, specifications or even guidelines on thermal damage caused by infrared lasers?

In the BBC News article, a laser-damaged camera in an unmanned car describes a situation in which a particularly powerful infrared laser emitted by the LIDAR of a prototype car at CES damaged the camera's sensor from a photographer.

Question: Are there standards, specifications or even guidelines in the sensor or camera manufacturing industries for thermal damage due to intense light sources?

  • If a LIDAR manufacturer wanted to be responsible and put in place a system that he thought would probably not damage security cameras and traffic cameras up and down the street, could he turn around? to information or limit the laser emission? Maybe a maximum radiance value in each of several ranges of wavelengths?

  • Or if a camera manufacturer wanted to be responsible and build a camera that probably could not be damaged by a car, robot or other LIDAR system?

  • Or if a LIDAR was part of the display of another product (such as a car or a robot), but it may not be obvious to all members of the public that IR lasers are involved, and screen owners wanted to know what laser level could justify including a warning on the cameras?

Until now, answers to the question Are there industry standards or specifications regarding the resistance of image sensors to the damage caused by intense light?
Ask a question
are basically "no", but outdoor photography is so ubiquitous that the experience is plentiful.

Now, however, infrared laser beams in the eyes are something new and different, and they are invisible. So we do not necessarily know that we are photographing a laser until the point does not appear in the photo.

As I understand it, these LIDAR systems use wavelengths that are absorbed in the front of the eye and never pass through the lens and focus on a small dot on the retina. An anti-IR filter on the lens You can alleviate the problem, but an infrared blocking filter on the sensor near the fireplace can melt and break down for the obvious reason that it absorbs energy that is now focused on a small point.

Ms. Nazer added that for the cameras to be immune to high power laser beams, they needed an optical filter that removes infrared invisible to humans. However, this can affect night vision, when the infrared can be a benefit.

"AEye is known for its lidar units whose range is much longer than that of their competitors, ranging from 1 km to 200 m or 300 m," she said.

"In my opinion, AEye should not use their powerful fiber laser during shows."

dnd 5th – Does the evocation wizard evocation function increase the damage of the blocking blade?

Yes, this is the case, but only for one of the damage rolls.

Empowered evocation allows you to add your intelligence modifier to the damage roll of any wizard evoking spell that you cast and Blasting Blade is a spell. evocation that qualifies him for this class skill. Although, according to the PHB errata:

Authorized Evocation (p.117). "The damage roll" has been replaced by "a damage roll".

However, it does not specify which roll will be added, so you can choose the one to which you will add the extra damage (I suggest the initial roll).

Are the damage of the Solarian weapon magic?

The Solarian weapon says that it is supernatural, which means that it is magical. Does this mean that damage counts as magic for things like intangible creatures?

physics – Calculating the damage caused by a collision of objects

I have to calculate the damage resulting from a collision of two objects.

I found the formula for the resulting kinetic energy:

E = m * v² / 2

I guess I must also use the mass or size of objects.

It will make a difference if the spaceship collides with a mountain (which will certainly cause a lot of damage), or it hits a floating tennis ball, in which case neither of them causes damage.

5th dnd – How does the extra damage of the Grand Master of Arms feat combine with Extra Attack?

The +10 damage bonus does not cascade, but it applies to each attack.

Although group attacks often have advantages in terms of time and speed1 (some people like to use dice of different colors), you still have consider each attack separately. A Level 11 fighter using Extra Attack will launch three separate D20s, evaluating moves or misses for each one. Damage inflicted after each hit – all attack rolls you've dealt the -5 penalty deal +10 damage.

Compare the Grandmaster of arms The benefit of giving …

Before making a melee attack With a heavy weapon that you master well, you can choose to take a penalty of -5 on the attack roll. If the attack hits, you add +10 to the damage of the attack.

… at a barbarian Reckless attack functionality:

When you make your first attack on your turnyou may decide to attack recklessly. This gives you an edge over melee weapon attack throws by using force during this tour[…]

Note the underlined text in each. Grandmaster of arms is a choice made at each attack, while Reckless attack is done before the first attack and applies to the whole tour.

Thus, you can enable or disable GWM for each attack. Suppose you get a 18 on the dice, then take into account the applicable bonuses alongside the Great Weapon Master's -5 … and the DM tells you that you missed it. You know that 18 is a good roller in itself, which means that the target has a very high AC. In other attacks on the same turn, you may choose not to suffer the penalty (and not to gain damage) to increase your chance to hit.

1If you plan to launch all the attacks in advance for reasons of speed, fairness, you should state whether you are using GWM or not in advance. In this way, you do not make decisions about information that you do not actually have.

dnd 5th – Is the damage of the Chaos Bolt spell against the first target resolved before it goes to another creature?

How is the damage of the chaos the spell (XGtE, page 151; GGtR, page 67) applied?

It may sound simple, but I have read the description of the spell about twenty times and she does not say specifically.

You cast a mass of wavy and wavering chaotic energy on a creature at hand. Make a ranged attack against the target. On one stroke, the target suffers 2d8 + 1d6 damage.

If you get the same number on both d8's, the chaotic energy goes from the target to another creature of your choice within 10 yards. Launch a new attack roll against the new target and make a new damage roll, which could cause a chaotic energy boost.

A creature can only be targeted once each time this spell is cast.

You launch the attack, and say that it hits. Then you run 2d8 + 1d6, let's say both d8's are 5, which means that it would jump.

Here is the question. Are the damage resolved on the first target THEN attack the second and the second equally? Because of the "wild" perception of this spell, he would "hit" the first guy, but not damage him, but move on to the second, until you stop rolling the doubles.

Example:

I attack Bob (because that's Bob), and he has his buddies Ted and Dan. I roll to attack Bob, hit, deal damage: result is 8 + 8 + 6 (maximum damage, because Bob deserves it). That would mean that it would jump to say Ted (because screw Ted).

  • Bob would he take the 8 + 8 + 6, and then I would roll to touch and damage
    Ted?

Or:

  • Would not the damage to Bob happen, and instead of I would roll to hit
    and damage Ted?
