How much control do you have over a charmed creature from the Great Old One warlock’s Create Thrall feature?

In the Great Old One branch of Warlock, there is a Create Thrall effect, which states that if I touch an incapacitated creature it becomes charmed toward me – but it describes nothing else about the charming.

How much control do you have over the charmed person?

Most charming spells describe your limits on what you can do, such as that you can order them around but you can’t order them to do something against their nature. So are there any rules that cover charming in general?

I know the basic stuff listed in the Player’s Handbook, such as that charmed creatures cannot attack allies of the charmer – but does charming give any control over the charmed person?

Can you apply the Monk’s Martial Arts feature only to your attack roll but not your damage roll?

The Monk’s Martial Arts feature states:

You can use Dexterity instead of Strength for the attack and damage rolls of your unarmed strikes and monk weapons…

Originally I thought this meant you had to either replace use Strength for both rolls or use Dexterity for both rolls. But the section on Finesse weapons states:

When making an attack with a finesse weapon, you use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.

Both features have the same “for the attack and damage rolls” bit; however, Martial Arts lacks the requirement that you must use the same modifier for both rolls. Does this mean that you are able to replace only the attack roll’s (or only the damage roll’s) modifier?

One reason you might want to mix up your modifiers is any time where you want to damage (and thus hit) a creature, but you don’t want to deal a lot of damage to it.
In a case like that you would want to use your higher modifier for the attack and your lower modifier for the damage.

Why is it not always possible to compute the centroid of feature vectors?

Hi in the data mining and machine learning course that I’m taking there is a subject on feature spaces and there is this part about feature vector aggregation and metric spaces that I don’t really understand. Now our curriculum is basically a huge presentation and the whole information about feature vector aggregation fits on one slide, anyway what I don’t understand is this:

For a given sample $ D$ the centroid can be computed as $ C_D = \frac{1}{|D|}\cdot\sum_{o\in D} o$

and then it says: “In a general metric space (that is, not a vector space), where we only have pairwise distances, it might not be possible to compute a centroid”

I don’t really think I understand what “only pairwise distance” means (my guess is it has something to do with the fact that a metric space defines the distances between all pairs of elements in its set) or why the consequence of it is that you can’t always compute the centroid.

I read somewhere that metric spaces does not have to define addition or scaling and if that is the case it makes sense to me that you can not calculate the centroid. Is this what it essentially is about or am I completely misunderstanding something?

With the ‘extra attack’ feature, will a creature’s ‘help’ give advantage to both attacks? [duplicate]

This question already has an answer here:

  • Do Actions with Multiple To Hit Rolls with Help provided get Advantage on all Rolls? 2 answers

Out in a foggy glade Agar is deeply focused on studying the local flora. While distracted, a poisonous snake creeps closer. Swoosh! As fangs begin to dig into Agar’s leg, his exceptionally trained falcon scoops up the snake. Agar draws his dagger and slashes out, with his second strike the snake is skewered. Agar’s companion floats to the ground and feasts on the downed serpent.

Aided by his companions help action, does Agar gain advantage with both strikes?

Agar the falconer; 7th level Ranger, Beast Master.

Which spell level does the Primal Draconic Bloodline sorcerer’s Variant Bloodline Arcana feature refer to?

The Sorcerer’s Variant Bloodline Arcana for the Primal Dragon bloodline says

Variant Bloodline Arcana: Whenever you cast a spell with an energy descriptor that matches your draconic bloodline’s energy type, you can reroll a number of damage dice equal to half the spell’s level.

Is that base spell level, or spell level after applying metamagic feats?

Instruction manual for each feature (page by page) on my web app? (instead of tooltip)

Problem:

I’m designing a web app that has features that people are not familiar with (learned this through user testing).
I need to guide users through, like hand-hold them, telling them what this page is for, what this term means.

For example, there will be a page called “Goal setting.” Users can write goals and key initiatives that contribute to each goal. users don’t know the difference between goals & key initiatives.

Some possible solutions:

1. Tooltip
but I’m opposed to it since it won’t be a quick tip)

2. Chatbot
– e.g. Intercom
– it is non-intrusive
– but it might get expensive

3. Standard side sheet Google Material’s example
– it can contain some long-form information as I intend to
– but I don’t have the top app bar in my app to anchor this side sheet onto

I’m leaning towards #3. If anyone has any decent examples of this or other ideas, I’d love to know!

Thank you so much 🙂

Does the Monk need to be aware of a charm effect to use the Stillness of Mind feature to end it?

I’ve done some research on the site and nothing is really concrete on the subject.

Monks’ Stillness of Mind feature states:

Starting at 7th level, you can use your action to end one effect on yourself that is causing you to be charmed or frightened.

Most charm spells and effects, however, do not inform the character that they are charmed. As a player, I see this as “no matter if I know in character or not, as a player, I can end a charm at the sacrifice of an action.”

My GM rules that “You have to be aware of the charm to end the spell.”

  1. Knowing that you’re charmed is OOC, so it’d be meta-gaming to suddenly use the effect without your character being given any reason to use it.
  2. Your character wouldn’t be using stillness of mind all day every day to avoid charm.
  3. Giving you the ability to end all charms would make charming you pointless
  4. Why doesn’t it just say “immunity to charm?” (which I respond by saying I have to sacrifice an action instead of just not being charmed).

A monk should know immediately if they are being charmed, as their training has developing their mind to detect outside influences and purge them accordingly. The common perception we came to is that “if I act out of character when charmed, I can detect the foreign influence and purge it.” But determining what is out of character in game can become a Meta-gaming issue due to everyone having different perspectives of my character.

Is this rule decided by DM discretion or is there concrete evidence supporting either side that has come to light?

(I’m biased as a player, but I would believe most GMs would not allow a monk to be basically immune to charm because it ruins a lot of clever encounters.)

Does the Ancestral Guardian barbarian’s Ancestral Protectors feature only work on your first attack after raging, or can you apply it every turn?

Does the Ancestral Protectors feature only work on your first attack after raging, or can you apply it every turn?

I have been wanting to make a Path of the Ancestral Guardian Barbarian, and I have been asking myself this question. Because if it does, it sounds pretty good, and maybe even on the overpowered side of things. Just imagine it against a boss.
