dnd 5e – House Rule – Upcasting Enlarge / Reduce to extend duration

The party is deep into my 5e-updated classic Greyhawk Giants series.

The hill giants and their orc and goblin minions have attacked the Sterish city of Headwater and have taken about a quarter of the city. The party is about to embark on a mission to go behind enemy lines, kidnap and assassinate a stone giant who is critical to the hill giants’ city / siege offensive as being their only trained engineer. While the party’s patron recognizes that the stone giant needs to die, she also recognizes that at present the Stone Giant Thane has not joined the giant alliance and wants to keep it that way. Thus, she is requesting that they carry the body of the slain giant honorably back to his Thane in an effort to preserve a fragile peace between the humans and the stone giants. I would like the party to be able to accept this mission, without it becoming either a logistical challenge involving wagons and draft animals, or without loaning them a portable hole.

Instead, I would like to provide them with a version of the Enlarge / Reduce spell which is in all aspects identical to the original except that it can be upcast to extend the duration.

I figure the giant is 17 feet high and 1000 pounds; after reduce it would be 8.5 feet and a manageable 125 pounds.

For this version of Enlarge / Reduce I am proposing that:

When cast at 3rd level against living creatures, it lasts 10 minutes

When cast at 3rd level against objects, it lasts 1 hour

When cast at 4th level against living creatures, it lasts 1 hour (similar to polymorph)

When cast at 4th level against objects, it lasts 8 hours

When cast at 5th level against living creatures, it lasts 8 hours (much less than geas)

When cast at 5th level against objects, it lasts 24 hours

The party Wizard is currently 8th level and getting close to 9th. Requiring her to use both her fourth level slots and maintain concentration for the duration of travel every day in order to move swiftly and stealthily into the mountains with the body is just the right level of challenge for the group.

My only concern is that allowing this version of the spell to the party wizard permanently will have some unforeseen interaction with some other spell, ability, or item that I will later regret. This question, for example, asks about upcasting enlarge to permit two changes in creature size, and answers identify the interaction with levitation and grappling being problematic. I am interested in a similar troubleshooting review.

dnd 5e – Can a wizard use his familiar’s senses to enlarge his “you can see” area?

Yes, you can teleport to somewhere your familiar sees provided that you are currently seeing through it’s eyes.

From the Find Familiar spell:

…as an action, you can see through your familiar’s eyes… (PHB 240)

If you’ve taken the action to see through your familiar’s eyes, and then cast Misty Step, then yes, you can teleport to somewhere your familiar can see, provided that it’s not more than 30′ from your current location.

dnd 5e – Cast Enlarge on a vial of acid then Catapult it. 8X damage?

Enlarge/Reduce does nothing to change the damage of Vial of Acid.

Enlarge says:

The target’s size doubles in all dimensions, and its weight is multiplied by eight. This growth increases its size by one category– from Medium to Large, for example. If there isn’t enough room for the target to double its size, the creature or object attains the maximum possible size in the space available. Until the spell ends, the target also has advantage on Strength checks and Strength saving throws. The target’s weapons also grow to match its new size. While these weapons are enlarged, the target’s attacks with them deal 1d4 extra damage.

If you use Enlarge to enlarge a vial of acid, all it does is make it bigger. That’s it. It doesn’t change the damage, because nothing in the spell says it changes the damage. See here for more details on “spells only do what they say they do”: What is the source of the “spells do only what they say they do” rules interpretation principle?

This seems pretty intuitive from a balance perspective. Vials of Acid are 25 gp, Enlarge/Reduce is a 2nd level spell, and catapult is a 1st level spell. Combining these very early game features shouldn’t produce an effect more powerful that many 6th and 7th level spells.

Using catapult can deal 4d8, but doesn’t activate the acid.

Catapult, which has a casting time of 1 Action, says:

If the object would strike a creature, that creature must make a Dexterity saving throw. On a failed save, the object strikes the target and stops moving. When the object strikes something, the object and what it strikes each take 3d8 bludgeoning damage. [Up casting to 2nd level adds 1d8 damage.]

However, Vial of Acid says:

As an action, you can splash the contents of this vial onto a creature within 5 feet of you or throw the vial up to 20 feet, shattering it on impact. In either case, make a ranged attack against a creature or object, treating the acid as an improvised weapon. On a hit, the target takes 2d6 acid damage.

These are two entirely different features that both require an action and cannot be used at the same time. You cannot both catapult and get the acid damage. You must choose one.

wcag – Is 200% browser enlarge an alternative for colors with contrast less than 4,51:1?

Short Answer

No, it doesn’t work like this. The rules are for 100% zoom. Either:

  • increase the font size to 19px and bold
  • 24px not bold
  • increase the colour contrast to 4.5:1 (ideally 7:1 to make you AAA compliant in that area).

Longer Answer

You are approaching this from the wrong angle. You are trying to make sure your site is compliant rather than as accessible and usable as possible.

Low contrast text is not just a problem for people with colour contrast perception impairments, it also affects users with bright sunlight on their screen or people with cheap phones that have screens with poor contrast / brightness, or people who haven’t got their settings right on their monitor!

It also requires more effort from all users to read low contrast text, and more effort = lower conversions / time on the page as people have a short attention span nowadays.

Aim for a 7:1 contrast ratio at your 14px font size.

Even better, define your font size in em or rem and let the user’s font size settings dictate how big the font should be. Obviously this means ensuring the site can handle different font sizes using fluid layouts / containers. At this stage just increase your font colour contrast to 4.5:1.

Or if you really want to keep your low contrast text as you find it aesthetically pleasing and you aren’t bothered by the points I raised then you could always add a toolbar at the top of the page that lets users change the text colour. See this example where if you press “+ show preferences” it lets you adjust the site to your needs / preferences.

Focus – Does the short focal length of the eyes enlarge the moon?

Does the short focal length of the eyes enlarge the moon?

Enter the image description here

The real cause of the moon illusion?

As shown in the figure, the blue line is the lens, w is the height of the object, x is the height of the image, v is the image distance, u is the object distance and f is the focal length. The red line is the light path.
The relationship between u, v, f is

1 / u + 1 / v = 1 / f

and so

f = uv / (v + u) (1)

The observer's eyes are constant, so v is fixed. The distance between the observer and the object is constant, so u is also fixed. As soon as v and u are fixed, it can be known from equation (1) that f is also fixed. If v is fixed and u decreases, f also decreases.

Knowledge from similar triangles:

x / w = (v-f) / f = v / f-1

and so

x = w (v / f-1) (2)

According to formula (2), x increases when v and w are fixed, when f decreases.

If the observer observes the moon on the horizon due to the influence of mountains and trees, f is smaller than when observing the moon at the zenith. According to formula (2) we can know that x increases as f decreases. The viewer will feel that the moon is larger and closer on the horizon than the moon at the zenith.

I think that's the reason for the moon illusion.

Simple calculation

If you look at nearby trees with your eyes:

u = 200 m (assuming 200 m from the tree)

v = 0.024 m (eyeball diameter, assumed image length)

w = 10 m (provided the tree is 10 m high)

f = uv / (v + u)
= 0.0239971 m

x = w (v / f-1)
= 0.0012 m = 1.2 mm (height of the tree picture)

When you look at the zenith moon (without the influence of trees on the ground) with your eyes:

u = 380000000 m (distance from the observer to the moon)

v = 0.024 m

w = 3476000 meters (diameter of the moon)

f = uv / (v + u) = A (we set this focal length to A)

x = w (v / f-1)
= 0.000219537 m = 0.219537 mm

If you observe the moon towards the horizon with the focal length of the observation tree:

f = 0.0239971 m

x = w (v / f-1)
= 420.067 m

The observation of the moon image on the zenith is 0.219537 mm, and the observation of the moon image on the horizon is 420.067 m, which shows a big difference between the two. So if you use a focal length less than A, the moon will be "enlarged".

Of course, the eyes do not generally observe the moon with a focal length of 0.0239971 m. Because the picture may not be clear. If the image of the moon is not clear at this focal length, the eyes adjust the focal length. Set a focal length that is clear for imaging. This focal length is less than A, but it is the focal length for clear imaging. Since the moon is far away, the depth of field of the moon imaging is very large. Therefore, there is a focal length that is smaller than A and can reproduce clearly. The moon illusion is therefore caused by a relatively short focal length. I think that's why the moon illusion.

Does the short focal length of the eyes enlarge the moon?



dnd 5e – What should happen if you enlarge an explosive?

My thief played a bomb and hid from a wizard who would ignite it remotely when the guards approached it with magic. While they waited, the wizard came up with the good idea to throw "enlarge" at it and convert 1 pound of explosives to 8 pounds of explosives.

I winged it a little bit and the explosion was twice as big (hit everyone in 10 feet instead of 5) and did additional 1d4 damage, although this should be the effect if it's a weapon.

Is there a suitable way under RAW to deal with an "enlarged" explosive?
