Can a Changeling with the actor feat have permanent advantage and performance and Deception checks?

So the changeling’s shapeshift ability says that

As an action, you can change your appearance and your voice. You determine the specifics of the changes, including your coloration, hair length, sex, height and weight. You can make yourself appear as a member of another race, though none of your game statistics change. You can’t duplicate the appearance of a creature you’ve never seen, and you must adopt a form that has the same basic arrangement of limbs that you have. Your clothing and equipment aren’t changed by this trait.

So basically, as long as the person you are changing into is/ was a real person, you are always passing yourself off as a different person.

The Actor feat says

You gain +1 CHA, you have advantage on Deception and Performance checks when trying to pass yourself off as a different person, and you can mimic the speech of another person or the sounds made by other creatures that you have heard (for at least 1 minute).

So the way I read it, a changeling would always have advantage on Deception and Performance checks because they are always trying to pass themselves as a different person. Or is the meaning of the Actor feat that they only have advantage when they are trying to prove that they are a different person not in other situations? Really curious if this is kinda broken because a bard or rogue with expertise and advantage on all deception checks could be a crazy good liar.

Do racial features which grant advantage on specific ability/skill checks provide a benefit skill checks made with different abilities?

The rules for making skill checks are usually cut and dried. If a character is making a check to see if they can swim against a current, this would usually be a Strength (Athletics) check.

But the rules allow for unique circumstances to require skill checks with atypical abilities.

For example, if you have to swim from an offshore island to the mainland, your DM might call for a Constitution check to see if you have the stamina to make it that far. In this case, your DM might allow you to apply your proficiency in Athletics and ask for a Constitution (Athletics) check.

Certain races afford the character advantage on specific checks (most commonly Wisdom (Perception) checks that involve smell or vision).

I can imagine a situation where a DM might request an Intelligence (Perception) check to see if a character is able to identify which of two glasses of wine is poisoned or a Constitution (Perception) check to see if a character can keep their eyes on something flying very close to the sun without squinting.

In these atypical scenarios, does the creature’s racial benefit still give them advantage on the check in spite of the fact that the fundamental ability being used with their skill is not the one explicitly cited in the description of their racial feature?

A sustained spell should require multiples drain resistance checks?

We are playing a Shadowrun 5 campaign. When a mage cast a spell, it should roll a Drain resistance check. The GM is requiring multiple drain checks, one for each turn the mage sustain the spell (in case of sustained spells). But I don’t think that a spell requires multiples checks, just one right after casting the spell. What’s the correct rule?

Can the Echo Knight’s Echo make Skill Checks

In the Echo Knight subclass it states that the Echo “uses your saving throw bonus for [saving throws]”, but says nothing about being able to make skill checks with the Echo. I’m primarily concerned about skill checks like stealth and acrobatics/athletics, things you might want to make in the course of combat or while using the Echo as a scout before combat (like with the Echo Avatar feature); I don’t plan on letting the Echo make separate knowledge checks to recall information.

So, does the Echo have the ability to make skill checks, and if it does, what bonuses does it have to those skills?

Is there any official rule softening power checks to NPCs in Ravenloft?

My players have scaped Aggarath to find themselves in Falkovnia. They started to walk to south trying reach Calimshan (they came from Toril) and instead, approached Aerie and had their first battle with a elite patrol of Talons. The session ended there and I begun to think about next plot. I readed ‘Death Unchained’ and 2nd edition Ravenloft campaign books and was creating Aerie’s leader character, Rudolph, a young Talon of Taladas, ‘today’ 64 years old, when I realized he had to be already a monster (minimum stage X – demilord serving Drakov). Torture is an automatic power check (‘+’ in table 16 of ‘Domains of Dread’). Worst, the entire military of Falkovnia (just in Lekar, more than 3000 human beings), certainly is already partial physical monsters. Drinking Drakov’s potion is not a pass to commit torture without ‘punishment’ (mainly because the NPC knew what Talons do and choose to be above peasants). So, even with certain high death rates among military, any official rule softening power checks to NPCs in Ravenloft or Falkovnia is a nest of future darklords?

checks if a tree is a full binary tree

I have to write an algorithm that checks if a tree is full binary tree (each node, except the leaves, must have 2 children), but I don’t know if this version is correct.

 isComplete(u)  {         if(u == NULL)                 return false         else         {                 left = isComplete(u.left);                 right = isComplete(u.right);                 complete = left && right;                  return complete.         } } 

Converting difficulty class (DC) of checks from D&D 3E to 5E

I’m looking at converting the 5th-level D&D 3E adventure The Speaker in Dreams to the fifth edition and I’m noticing a lot of DCs from 20 to 30. Were difficulty classes higher in 3E or were players able to consistently roll higher checks because of a specific mechanic compared to 5E? Should I be reducing the DCs of checks when converting, if so is there a good fixed value or formula to decrease the DCs by?

On TLS-enabled nginx/httpd, is “ssl_verify_client optional_no_ca” disabling TLS’s “CertificateVerify” checks?

I’m looking for an helping hand with my https nginx setup. I require my application to be exposed through an nginx frontend, offloading TLS. Easy !
The thing is, I need to have Certificate-based client authentication, and my application cannot be advertising a list of CAs it accepts as it will disclose information about my clients.

As a result I am building up a solution based on the optional_no_ca parameter of nginx.

Sadly, this workflow is not discussed on the TLS RFC, and I’m willing to confirm that the CertificateVerify is still part of the verifications done by Nginx/OpenSSL .

I’m willing to do my authentication in 2 phases :
1- ClientCertificate & TLS validation – On Nginx ( to avoid replay and certificate forgery )
2- Certificate validity, CAs and CN validation on Application.

This can only be secure if the CertificateVerify is done properly on Nginx side, as it will be impossible for my application to do it, since it’s not terminating TLS itself ( and cannot ).

Would anyone have confirmations ? Or ideas on how to test this without falling down to scappy ?

What spells, items, and abilities improve wisdom ability checks?

My level 3 cleric is trying to cast a level 5 spell-scroll, and to optimize the chances of success, I want to stack as many positive ability check buffs on him as possible. Preferrably lower-level/easy to access ones. So far I have:

  • Enhance Ability (Wisdom)
  • Bardic Inspiration
  • Guidance
  • Portent (Divination Wizard)

I’m sure I’m missing a ton.
