How to describe Symbiotic entity wildshape from the spore druid? [closed]

The spores druid have a new type of wild shape the symbiotic entity. In the rules is stated:

At 2nd level, you gain the ability to channel magic into your spores. As an action, you can expend a use of your Wild Shape feature to awaken those spores.

But wild shape is like a metamorphous trait, right? And what exactly is "awakening the spores", you became a giant mushroom? Mushrooms are grown on your back? But if they just grow with the wild shape how you can spread spores? It’s just a random question, but I like to describe every single ability that I use.

How to describe Deterministic Transitive Closure in FOL

In "Finite Model Theory and Its Applications", page 152, it is said that Deterministic Transitive Closure, on ordered finite structures, captures LOGSPACE.

Hence, taking into account that FOL captures LOGSPACE, it should be possible to:

• Given a functional relation R(X,Y) (e.g. "motherOf(X,Y)")
• It should be possible to define, in FOL, a predicate T(X,Y) that captures its transitive closure (e.g. "femaleAncestor(X, Y)")

I would like to know how to define such predicate. This would be quite easy in Datalog, using recursion, but it should be possible to define it without recursion, which is the question that puzzles me.

Describe this Turing machines

I need to describe a Turing machine that it can be multitape.

$$M = (Q,Σ,Γ,δ,q_0,q_a,q_r)$$.

Who decide that language.

$$L=\{\#uqv\#u’q’v’\#:u,v,u’v’∈(Γ\setminus\{\sqcup\}^*,q,q’∈ Q$$ and$$(u,q,v) \Rightarrow (u’,q’,v’)\}$$ according to M.

on alphabet.

$$\Sigma’=Q\cup(Γ\setminus\{\sqcup\})\cup\{\#\}$$

But I not sure to understand the language and the alphabet $$\Sigma’$$, do you have exemple that could help me to understand. Thanks

How to describe that an enemy can avoid opportunity attacks?

I’m the DM of my group. When we are playing I try to describe the effects and actions of enemies and npcs without spelling out exactly what they are to keep some mystique to the actions. Like describing that “the mage shoots a large electrical beam” instead of calling it lighting bolt outright.

I want to add a Flyby effect to a soon to be boss enemy, the description of Flyby is

Flyby: The [creature] doesn’t provoke Opportunity Attacks when it flies out of an enemy’s reach.

However I don’t want to make it seem as if the enemy is avoiding opportunity attacks just because, but neither I want to spell the effect out so they still have to think about it.

How then can I describe an enemy that has immunity to Opportunity Attacks without saying it exactly like that?

Which works best to describe character, item or dungeon properties: Affix or Trait?

I am working on an RPG portion of my game called “The Underground King“.

My item generator uses the same properties that also apply to characters, vehicles and racing levels (dungeons for short).

I am torn between using the term “Affix” and the term “Trait” to describe the procedurally generated properties, mainly because English is not my first language, and there may be a clear difference in usage between the two.

Examples of traits: Hearty: For items, it gives 5 more HP, for characters they have 5 more HP, for vehicles they have 5 more durability, for dungeons, enemies have 5 HP each. Indomitable: For items, characters and vehicles, it gives the player the ability to ressurect at 100% hp, once dead. For the dungeon, dead enemies remain invulnerable for a few seconds after being dead.

I am open to either opinions or arguments for any of them. Thanks!

Should the DM describe NPC spellcasting so that players can use Counterspell?

Going into battle, standing in front of a medusa and 2 nagas. I have line of sight on all 3. The DM says to make wisdom saving throw, without describing why.

After failing the saving throw, I’m mind controlled by a naga. When I question why, the DM tells me the naga cast a spell (but wouldn’t tell me what one, I assume dominate person, or charm person). To which, I respond, “okay I would use counterspell when I see the naga casting a spell in front of me though.”

The DM claimed I should have used counterspell earlier.

Considering that I could see the creature, am I correct in assuming there should have been a description of “you see the naga wave it’s arms” or “you see the naga begin to chant” before being asked to make a wisdom saving throw? Something to indicate this was a spell and not a effect of the room or something I couldn’t avoid?

P.S. He knows I have counterspell in a ring of spell storing ready.

How specifically do I need to describe (in words) the language of a regular expression?

For the regular expression (abab)a I want to learn how to describe it in words. I know there are an even nmber of bs but how much do I need to explain it? Do I need to explain it enough that each possible string can be produced from my explanation? Another example is (a*[bac]) where I would describe it as as string over {a,b,c} where there are the same number of a’s and c’s.

Thank you.

Describe a Turing machine which decides for any two words w,v in {a}* whether or. not their lengths have the same parity

Describe formally (by means of a transition function) a Turing machine which decides for any two words w, v in {a}* whether or not their lengths have the same parity (i.e., either both lengths are even or both lengths are odd). You may assume that the input is the word of the kind w*v, where * is a new letter.

How to write grammar production rules to describe recursive structures?

I’m trying to describe a data structure by production rules. The structure is recursive; say a list of type $$A$$ made of elements of type $$A$$ or $$B$$.

Writing the grammar, I build this:

$$(S \rightarrow AS|ε)$$ $$(A \rightarrow AA|bA|ε)$$

where $$b$$ is a terminal representing element $$B$$ of my list.

The production $$A \rightarrow AA$$ got me a little baffled… is there something right? Thank you.
