Can a character who was True Polymorphed into a Dragon Change Shape back into their original form? [duplicate]

This question already has an answer here:

  • Can you use a Dragon's Change Shape Ability to Turn Back Into Yourself? 2 answers

A level 20 character can be changed permanently by True Polymorph into an Ancient Brass Dragon (CR 20). Ancient Brass Dragons have the Change Shape action that says,

The dragon magically polymorphs into a humanoid or beast that has a challenge rating no higher than its own, or back into its true form. It reverts to its true form if it dies. Any equipment it is wearing or carrying is absorbed or borne by the new form (the dragon’s choice).

I’m unclear if challenge rating could refer to total character level of a specific character, but if it does, could this dragon change into it’s original body?

Should your font size change based on size and orientation of the device?

I am created a cross platform app and I was wondering if and when fonts should scale based on the size of the screen. Also, I was wondering if the scales of fonts should change based on the orientation of the device or on very large/very wide devices.

For example, I have one screen which has the text as the main subject of the screen. This font looks a bit odd on different devices when it doesn’t scale.

On buttons, however, the font looks fine without scaling.

Also, there are certain titles that look fine with rotations and others that look atrocious.

Are there any guidelines about which, if any bits of text, should scale and based on what (ppi, size of phone)? I know the common web standard is rem, but that doesn’t exist in mobile in certain cases (including mine).

“How to read rules” — how did this change between editions?

It seems the role of rules1 was changed throughout the history of D&D.

For instance, as this answer says, there was an explicit destinction between “crunch” and “fluff” in fourth edition:

a distinction between “ignorable fluff” and the “real rules”

Such a separation is a prominent feature of 4e

Aside from this, were there any other changes on how the rules were supposed to be interpreted between editions? I’m primarily interested in the most popular “modern-ish” editions, so narrowing the question, how was the role of rules changed in 5th edition in comparison to 3.5e?

1: By “the role of rules” I mean “how the rules are meant to be used in order to run a game”.

Why does price change in second page in many apps

In food delivery apps and cab aggregator apps there is price difference in India.

In food apps – I add the items from restaurant menu. it shows total of 240 rs. I navigate to place order page. All the additional charges and taxes are shown now.

In cab aggregator apps they show a price in first page and when you chose a particular category or variant and proceed to the second page all the taxes and deposits and other fares get added and price gets inflated.

Isn’t this a dark pattern? As a user I often feel misled and confused with this kind of pricing tactics. Is it just me or anyone else feels the same? So the question is why does the industry practice this? I have some theories, but I am interested in knowing what others think.

How can we change the alignment of our black dragon hatchling?

My fiance is running a campaign and the players have the opportunity to obtain a wyrmling black dragon. Now black dragons are chaotic evil, but the monk of the group believes that it shouldn’t be killed outright just due to the fact that its race tends to be evil. He wants to attempt to teach and raise it in goodly or rather, less evil ways, but the other players want a backup plan to change its alignment if worst comes to worst. The problem is, the DM doesn’t see anything involving forced alignment changes. Is there a mechanical way to handle this or is it going to be DM decision to add something to the game that isn’t currently there?

Undoing the alignment change of the Book of Vile Darkness [duplicate]

  • How can we change the alignment of our black dragon hatchling? 4 answers

So I’m the DM in a campaign (which I know gives me a lot of leeway) but I try to stick as close to the books as I can. One of the NPCs attuned to the Book of Vile Darkness, and failed the associated charisma save, so is now of neutral evil alignment.

One of the PCs is related to and will likely want to save this NPC without killing them. So my question is, are there any RAW ways for the party to change the alignment of an NPC?

If there are no RAW ways, what would be an appropriate challenge for a party that will likely be 12th level by that time?
