How to handle a party member spontaneously not showing up?

I am the GM of a party that consists of two family fathers, one guy working on a oil platform and another freelancer working in the film industry. So it happens quite often that one member spontaneously cancels. If we are in a dungeon and it is all about fighting, this usually is not a big problem – I just tune the encounter down a bit – but concerning role-playing and storyline, I have a bit of a hassle.

Let me give you an example: The party travels to Cheliax. The elf becomes alcohol-addicted since he could not handle the death of another party member. The orc and the human decided to bring him back to a rehab center in Absalom. I already prepared the adventure, but the elf’s player gets a call from his boss and has to work spontaneously. So he cancels 2 hours before we start.

How can such a situation be handled?

Is the problem that determines whenever the word member $\in$ L(M) decidable or not?

Given a Turing machine M on alphabet {m,e,b,r} we’re asked to determine if member $ \in$ L(M). You must realize that M is not one specific machine and can be any turing Machine with the same alphabet. My goal is to determine whenever this problem is decidable or not.

My idea was to use mapping reducibility. The goal was to see if we can translate all problems from $ A_{TM}$ which is known to be undecidable into our current problem. This would make our current problem undecidable by contagion. However I’m struggling in doing so because I’m not sure if it’s possible. $ A_{TM}$ is defined as a Turing machine M that accepts the word w.

Any help to get unstuck would be appreciated.

Decide if a string is a member of a language that represents $P$?

For some enumeration of the complexity class P (such as this as an example: How does an enumerator for machines for languages work?), for each string 𝑝 in the enumeration, does there exist some other string (certificate) 𝑐 that allows you to verify 𝑝 is a member of the enumeration in poly time? I believe that it might be possible in poly time because all we have to do is check if a string fits some certain format (format of the encoding)?

A decision problem $ P$ is poly time verifiable iff there is an algorithm 𝑉 called verifier such that if $ P(w)=$ π‘ŒπΈπ‘† then there is a string $ c$ s.t. $ 𝑉(w,c)=$ π‘ŒπΈπ‘†, if $ P(w)=𝑁𝑂$ then for all strings $ c$ , $ 𝑉(w,c)=$ 𝑁𝑂 and V runs in $ O(w^{k})$ for some constant $ k$ for all inputs $ w$ .

I am a member of the Administrators group on a Windows 7 box, how can I spawn a reverse shell with elevated privileges?

I am learning Windows Privilege escalation. I’ve managed to add a user to the Administrators group but I don’t know how to execute nc.exe, present in the Temp dir, with eleavated privileges. My end goal, here, is to get a reverse-shell as nt authority\system, with this newly created privileges for the user user.

Following are some of the details on the Windows box:

w is a member of L iff w is a member of L?

A word w is a member of a language L iff it is a member of the language L, ie. the condition of w’s membership to L is that it be a member of L. This is the definition of the language.

Without ahead of time specifically declaring a list of words which are in L–that would then be in L by definition–is this language decidable? Or, do we end up (as suspected), for any machine that decides L, and on any input, in an infinite loop due to the self-reference: we go to check if w is in L and then see that we need to check if w is in L and then see that we need to check if w is in L…ad inf and this language is undecidable?

PS. Is there a name for a language that refers to itself in its definition?

Thank you!

What happens when a party’s member uses an healing spell on an unconscious PC who has spell resistance?

The Spell Resistance (Ex) ability reads, in part:

The possessor does not have to do anything special to use spell resistance. The creature need not even be aware of the threat for its spell resistance to operate.

My PC fell unconscious in the middle of a fight, when the cleric approached me to use Cure Serious Wounds (Player’s Handbook v.3.5, p. 215) I stated that I had Spell Resistance and I didn’t lower it in order to protect myself while I was on the ground. Our DM ruled that being unconscious implies that my spell resistance isn’t active.

This was certaintly helpful, my PC would be already dead if it wasn’t for that Cure Serious Wounds, but this takes me to the point: was it all legal?

Does an harmless spell has to pass the caster level check in order to affect a creature with Spell Resistance?

Does an unconscious creature has Spell Resistance equal to zero?

In Eberron, it’s possible for a character to be a member of two or more Guilds?

TL;DR: A character who is a member of the Blademarks Guild of House Deneith was invited to join the Clifftop Adventures’ Guild and he accepted, will there be any consequences for him?

Detailed Question:

I’m running a campaing in the setting of Eberron, using the Rising From the Last War as a guiding to the setting. My idea is that the players eventually join the Clifftop Adventurers’ Guild.

But one of the the players made a human fighter who is from Karrnath who, for personal reasons, joined the Blademarks Guild of House Deneith. He is not a dragonmarked character, he is just a fighter who sell his sword to the Guild.

Now, as a reason for him to go to Sharn, I said that he is receiving few jobs from the guild in Karrnath and wants to see if the guild branch in Sharn has more services for him. I recently run the first session where they helped a villager, and a member of the Clifftop Guild became admired with the party display of autruism and strengh, and he invited them to join the guild. The players accepted the invitation, but afterwards I started to wonder how this would play with that character relationship with the Blademarks Guild

Are there any explicts impeditive for him to join the Clifftop Guild?

Does he needs to choose between one guild or other, or he can be a member of both guilds and take job from them as he wishes?

Since he is not a dragonmark character, I thought that he’s relationship with the guild was more flexible, but I didn’t find any source that could provide more details about these relationships between a guild and they members.

If possible, I wanted to clear these questions:

  • Can he be a member of both guilds?
  • If not, will the Blademarks Guild recent him if he chooses the Clifftop over them?

What ability check is the most appropriate for disarming a weapon from a creature grappled by another party member?

It’s my first post here. I am a DM running a 5e campaign for my friends.

During our last session, the characters were surprised by a creature polymorphed to look like a friendly NPC. The creature took their friend’s weapon (a one handed mace) and was using it to attack them. One of the party members had jumped off a cart and put themselves and the creature into grappled and prone condition states on the ground.

A different party member approached and said “I want to grab the weapon from [the enemy] and toss it away.” In response, I asked for a Dexterity (Sleight of Hand) check to see if they could remove the weapon. Was this the best-fit ability check for this scenario?

My reasoning for the check was:

  1. The Grappled nor Prone conditions state anything about the enemy being disarmed or losing control of their weapon (Players Handbook, Grappled – pg. 290, Prone – pg. 292), so I saw the active fighting and resistance displayed by the antagonist as creating a situation where it wasn’t an easy feat to simply grab the weapon.
  2. I think the action would require precise, dexterous movement of the hand to grab it while the enemy flails and combats their assailant. PHB states Dexterity ability checks “measure agility” (PHB, pg. 173).
  3. Sleight of Hand use on pg. 177 of the PHB doesn’t state anything about removing a weapon, just subtly removing a coinpurse without the person knowing. However, I also interpret it as the ability to manipulate an object on another’s body in a tricky situation.

After thinking on it, I feel as though a Strength (Sleight of Hand) check may have been more appropriate because the PC wresting the weapon away was a dwarf not prone to stealthy actions, but I would love some feedback on more specific rulings I’m missing.

Thank you for any help you may provide.

How do NPC’s of a faction know one of the party members is a member of their faction? (careful: minor spoilers in question)

I’m currently running LMoP for 4 players. One of them has already joined the Lords’ Alliance, and I expect another to join the Emerald Enclave in the near future.

I’m planning to run SKT next, and have already started reading the book. The factions are mentioned quite often, and usually in a way that if one is a member of the faction they can get free lodgings/special items/a special quest.

I wonder though… how would they know they are part of their faction?

  • Would they be wearing a symbol on their clothes (such as a pin)?
  • Would they have to explicitly state to the NPC that they are a part of this faction?
  • Or would the NPCs simply be already informed about the new member and his/her appearance?

Any other possibilities?
