Can I true polymorph into an Ancient Brass Dragon, and then use its Change Shape ability?

If I were to cast True Polymorph (which permits all creatures, not just beasts, as the regular Polymorph does) on myself to turn myself into, say, an Ancient Brass Dragon (provided that I’m level 20, which is required due that dragon’s CR) – could I then use the Change Shape “racial” feature of the dragon?

Change Shape. 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…

True Polymorph:

Choose one creature […] that you can see within range. You transform the creature into a different creature, […]. The transformation lasts for the duration, or until the target drops to 0 hit points or dies. If you concentrate on this spell for the full duration, the transformation becomes permanent.
Shapechangers aren’t affected by this spell. […].

Creature into Creature
[…] The target’s game statistics, including mental ability scores, are replaced by the statistics of the new form. It retains its alignment and personality. […]

I can’t find anything in the spell that would prevent one from doing so. The only thing that might come into play is the phrase “Shapechangers aren’t affected by this spell”. You as the caster are not a shapechanger, however, so even though you transform into a shapechanger, you aren’t when you cast the spell.

Can you get infinite spells through True Polymorph and Shapechange

So, let’s say you’re a level 17+ Wizard and you cast True Polymorph on yourself to turn yourself into a CR 17 Adult Gold Dragon. This grants you the stat block of said Adult Gold Dragon, granting you the statblock of said Gold Dragon, including its Shapechange ability, allowing it to assume the form of “a humanoid or beast with a Challenge Rating no higher than its own”. It uses this ability to turn into a CR 12 Archmage, which has the Spellcasting feature, allowing it to cast spells using as an 18th level spellcaster, using its intelligence score.

Once they expend a number of spell slots from its new form, it proceeds to use its new 9th-level spell slot to cast True Polymorph on itself again, turning into a brand new Adult Gold Dragon form, and then using Shapechange to turn into a brand new Archmage form, and then repeats this process to gain an infinite number of spell slots.

Is there anything that prevents this from working? I know that True Polymorph is a Concentration spell, so the first True Polymorph would end when they cast the second one, I don’t think they lose the spell they’re Concentrating on if they lose the Spellcasting feature that gave them the slot in the first place? 5e doesn’t have any hidden rules, and there doesn’t seem to be anything about it working that way in the Spellcasting chapter of the PHB – and if it did work that way, wouldn’t it break Polymorph spells in general, since they lose their Spellcasting class feature while Polymorphed?

Obviously the chain gets broken if they fail a Concentration saving throw, but they’d get the Adult Gold Dragon’s Legendary Resistance to help them out, there – and it’d get reset every time they True Polymorph themselves, too.

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?

Are these homebrewed rules for True Drake balanced?

Since there are no rules for True Drakes in the fifth edition of shadowrun, and based on comments it seems likely there won’t be in the near future, I’ve decided to add them as a house-rule. Since I’m quite new to Shadowrun I would like to know if the following implementation would be unbalanced in any way when compared to similar options found in the sourcebooks, and suggestions for improving it. The rules provided are an adaptation of 4th edition’s The Clutch of Dragons rules for True Drakes.

Note: For simplicity sake, instead of employing the “two forms two sets of attributes” we see in Shapeshifter, I’ve decided to employ the “dracoform is metahuman plus bonuses” as Drakes do. While this may seem odd since their metahuman form is “secondary”, I think it simplifies things and makes attribute improvement worthwile. The cost for the form is the cost of being a Drake plus the cost of Dracoform Mastery, since besides that I think advantages and disadvantages even out. Having a higher reward on the “Wanted” negative quality all drakes get might further balance both.

Also, unlike Drakes, True Drakes need to pay the full cost, there’s not a possibility to have it latent or “unactive until fully paid”. Which means that only with point-buy could a True Drake be created.

Fluff: True Drakes are beings created as a human-sized dracoform by Great Dragons, in an extenuating and costly ritual. They are able to shift to metahuman form at will. They are extremely rare, since few beings can create them and even then it’s hard.

True Drake (125 Karma):

Since Dracoform is their natural form, all True Drakes are considered to have the drake power “Dracoform mastery” from the get-go.

True Drakes get the following optional drake powers for their dracoform: Magical Guard (9 Karma), Regeneration (19 Karma) and their limit for “Improved Natural Armor” is their Magic +2 instead of just their Magic.

True Drakes cannot receive any Augmentations that reduce their essence. They also cannot be infected or carriers of the HMHVV.

True Drakes starting Essence is 8. True Drakes maximum Edge becomes 8 and they cannot take the Lucky quality.

Is it true that argon2i is “preferred for password hashing and key derivation”?

I was looking at the wiki for the node-argon2 package in npm, when I came around this justification for using argon2i as the default mode:

The variant of the hash function. Argon2 has several variants with different aims:

argon2d is faster and highly resistant against GPU attacks, which is useful for cryptocurrency argon2i is slower and resistant against tradeoff attacks, which is preferred for password hashing and key derivation argon2id is a hybrid combination of the above, being resistant against GPU and tradeoff attacks 

This security.stackexchange post suggests that side channel attacks are not a big concern on server(which I assume is the application here), and that argon2id or argon2d would be better choices.

Additionally the claim that argon2i is better for password hashing because its slower seem dubious, since the number of iterations can be adjusted for any mode

Is there any truth to the statement “argon2i is slower and resistant against tradeoff attacks, which is preferred for password hashing and key derivation”?

Does a caster under the effect of a True Polymorph spell retain their class levels?

The true polymorph spell specifies that:

The target’s game statistics, including mental ability scores, are replaced by the statistics of its new form … The creature is limited in the actions it can perform by the nature of its new form, and it can’t speak, cast spells, or take any other action that requires hands or speech, unless its new form is capable of such actions.

So let’s take the example of a level 20 Sorcerer who has permanently True Polymorphed himself into a Planetar Angel.

The sorcerer’s game statistics are replaced by those of the new form. Does this include class levels? The angel’s form doesn’t limit the physical ability to use spellcasting, but does the sorcerer retain their class-given spellcasting ability?

The wording of the spell seems to imply the caster is still able to cast their spells, as long as the new form is physically capable of performing the required components.

How about a dragon? They are capable of verbal and somatic components, which are the only requirements for spell usage.
