What are the 5E origins of the Mind Flayers?

The 3rd Edition D&D sourcebook Lords of Madness says the illithid species originated in the distant future and somehow traveled to the distant past to avoid extinction. A trilogy of 2nd Edition modules says they came from another plane known as Penumbra without the time travel. Has the origin of these creatures been rewritten for 5th Edition, and if so, as how?

What happens when a Demon tries to Read an Angel’s Mind?

What happens if a Demon tries the Mind Reading form ability on an angel? The rules from the DtD manual state:

System: The demon only has to see her intended target; the target does not have to see the demon or know she is there. As a reflexive action, the player rolls her Wits + Persuasion + Primum vs. Resolve + Primum. If successful, the demon can read the surface thoughts of the victim for as long as she maintains concentration.

It’s odd that the manual assumes that the Demon is trying to read the mind of another Demon (hence the “vs. Resolve + Primum”). Angel’s don’t have Resolve, so maybe Resistance+Rank?

If it’s successful, does the Demon know that the target is an Angel? Does the Angel have any way to detect the use of an ability on them? Otherwise, this seems like a perfect Angel-detector.

Can the DM change his/her mind after a player has rolled?

I’m new to D&D, and have been participating in campaigns that are meant to be completed within a single night.

Last weekend, the DM requested that I make a Sleight of Hand check for an action that I wanted to perform. I rolled a 19, and the DM became visibly annoyed. After a pause, the DM said, “Actually, roll at a disadvantage, because [x] is currently happening.”

I immediately thought it was unfair, but I didn’t want to object, because I’ve only showed up to a couple of these weekend campaigns. So I rolled again and had a critical miss, which pleased my DM and (obviously) annoyed me.

Question: Can a DM change their mind on the requirements for a roll after the roll has already been made?

Does Ring of Mind Shielding or Mindblank block the Dream spell? If not, what does?

As the question states. What spells and/or effects apart from not sleeping give someone immunity from being contacted with Dream?

It would seem to me that as long as you’re on the same plane as your target and your target is asleep, there is no RAW way for your target to avoid being targeted by Dream.

How to decide for a database structure for a financial accounting app (keeping in mind scaling)?

We are building a financial accounting application for users to manage single and multiple companies under them. The user can be an accountant with n number of companies under it or a single company itself. We are trying to understand how the database for such an application needs to be designed.


  1. The ability of an accountant to see all open invoices across all the companies he is handling.

  2. The ability to archive datasets of companies when they leave us.

  3. The ability to fetch data from multiple companies under one accountant to generate reports.

Database structure:

There are three possible database structures but we need to know which one best suits us:

  1. Have a parent database that holds all accounts and company information. Every company getis its own database to handle and store all transactions.

  2. have a single DB to hold all users and company profile data and every individual company gets its own set of tables to store transactions.

  3. Have a single DB that holds all the transaction data of all companies in a single table called transactions.

We are trying to understand which DB architecture suits us the best. I have MySQL/MariaDB in mind(solely because data is all relational) but if you think other databases would be better, i would definitely like to know more about it.

Is there a way to get Decisive Strike with a mind blade?

I’m working on a Darth Vader build for a competition. To represent the light saber, I would really like to use mind blade (from the 3.0 Soulknife prestige class, which is actually pretty cool, especially compared to the 3.5 base class). However, the Monk ACF Decisive Strike (which replaces Flurry of Blows) would make a fantastic addition to the build.

Problem is, Unorthodox Flurry and Whirling Steel Strike both have “flurry of blows class feature” as a prerequisite, so I can’t use either to make the mind blade a special monk weapon. My second thought was Shou Disciple, but it only lets you flurry with other weapons; it doesn’t make them special monk weapons, and thus it wouldn’t let you decisive strike with mind blade either. The Eberron Monk substitution levels give you Whirling Steel Strike as a bonus feat, which would normally obviate the need for the prerequisites… but explicitly still requires all prerequisites. There are also numerous classes that give you a “flurry” of some flavor, but none I’ve found so far are specifically a “flurry of blows” that would work as a monk-independent way of qualifying for one of the feats.

So how about it? Is there a way to make a mind blade, short sword, or longsword* count as a monk special weapon that doesn’t also require you to have Flurry of Blows? Or a way to count as having the “Flurry of Blows class feature” to qualify for a feat? Or for that matter, a way to get Decisive Strike without trading away Flurry of Blows?

*The Soulknife prestige class (Psionics Handbook pg 113) says the mind blade is “identical to” a short sword until level 8, at which point it’s “identical to” a longsword. As far as I’m concerned, that means any method that works for one of those also works for the mind blade. It also means longsword is the least preferable of the three.

How much damage does Mind Spike do at higher levels?

Mind spike, a 2nd level spell included in Xanathar’s Guide to Everything, uses different damage dice for the base damage and for additional damage when cast at higher levels. I have the First Printing of XGtE, which has the following text*:

Mind Spike

2nd-level divination


You reach into the mind of one creature you can see within range. The target must make a Wisdom saving throw, taking 3d8 psychic damage on a failed save, or half as much damage on a successful one.


At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.

I have not been able to find any other spells that use different damage dice sizes (d4, d6, d8, etc.) for the damage at the base level and the “At Higher Levels”. (The only quasi-exception are spells like ice storm that that use different damage dice at the base level for different damage types, but in this case the damage at higher levels uses the same die size as the matching type of damage at the base level.) So my suspicion is that this should do base damage of 3d6 or additional damage of 1d8 for each slot level above 2nd.

Has this been errata-ed, corrected in later printings, or is there any other evidence that this is a misprint?

When did the gith break free of the mind flayers?

In my recent question, How did the Duergar break free of the Mind Flayers?, in this answer it is stated that the Duergar freed themselves from the mind flayers in the year “c. –4000 DR”.

However, I cannot find anything online or in any 5e material that describes when the gith freed themselves from the mind flayers. I was curious to know how far apart these two revolts took place.

Is there any official lore that states when the gith freed themselves from the mind flayers?
