dnd 5e – How does haste interact with the heavy armor penalty?

For a character that is wearing heavy armor, but does not have the prerequisite strength, there is a 10ft speed penalty.

If the Armor table shows “Str 13” or “Str 15” in the Strength column for an armor type, the armor reduces the wearer’s speed by 10 feet unless the wearer has a Strength score equal to or higher than the listed score.

Haste doubles the speed of the person it was cast on.

Until the spell ends, the target’s speed is doubled

Since the movement speed of heavy armor is a fixed amount, does the doubling apply to the base speed or the current speed?
Eg. A human with a base speed of 30. They put on heavy armor and have their speed reduced to 20. Haste is cast on them, does their speed become 30×2 – 10 = 50 or (30-10)×2=40?

pathfinder 1e – DEX-focused heavy armour user – mithral full plate vs mithral breastplate

Your Dexterity bonus to AC is vastly superior to your armor bonus to AC, because your Dexterity bonus applies against touch attacks and your armor does not. That makes bonuses from Dex twice or more as valuable as bonuses from armor.

Moreover, a feat is an incredibly valuable resource, so you should always be very careful how you spend them, make sure whatever you get is worth the cost of spending a feat on it. Bluntly, Heavy Armor Proficiency is never worth that cost—you mostly get +2 more armored bonus to AC, which again is low-value, and then you take other penalties to boot.

Frankly, it’s entirely likely that your best option is actually a mithral chain shirt or darkleaf lamellar leather, rather than a mithral breastplate. Those have lower penalties, higher max Dex, and higher speed. I realize that takes you away from the Dex+heavy armor theme you had going on there, but at higher levels a +5 Dexterity bonus is rather poor for a Dexterity-focused character–you are quite likely to exceed that by a considerable margin, and therefore may very well reach a point where the lighter armor would be better than the mithral breastplate. This does depend on how high in level you expect to get, how likely you think it is that you’ll be able to trade your (heavily enchanted) mithral breastplate for an equivalent light armor, and so on, but in many games my preference would be for a lighter armor.

Speaking solely of AC, this kind of high-Dexterity build is mathematically your only hope of getting AC that’s worth much. Heavy armor simply doesn’t scale well enough, and buying a ring of protection and amulet of natural armor winds up wasting a ton of gold achieving mediocre AC. With high Dexterity, you still have to spend a ton of gold—gold that may very well be better spent elsewhere—but at least by the end of it you have respectable AC that may actually pose something of a problem for enemies. Otherwise, though, it is usually optimal in Pathfinder to ignore AC beyond the nearly-free AC you get from a +1 armor (and a +1 shield if using one), and never worry about it again thereafter. Your real defenses should come from special armor properties and wondrous items, which should give you real defenses like miss chances.

dnd 5e – Can the spell immovable object be used to carry very heavy things?

The spell immovable object from Explorer’s Guide to Wildemount (pg. 187) says:

You touch an object that weighs no more than 10 pounds and cause it to become magically fixed in place. You and the creatures you designate when you cast this spell can move the object normally. (…)

(…) a creature can use an action to make a Strength check against your spell save DC. On a success, the creature can move the object up to 10 feet.

At Higher Levels. If you cast this spell using a spell slot of 4th or 5th level, the DC to move the object increases by 5, it can carry up to 8,000 pounds of weight, and the duration increases to 24 hours. If you cast this spell using a spell slot of 6th level or higher, the DC to move the object increases by 10, it can carry up to 20,000 pounds of weight, and the effect is permanent until dispelled.

The two phrases I am interested in here are:

You … can move the object normally


it can carry up to 20,000 pounds of weight.

Suppose I cast immovable object at 6th level on a thin sheet of plywood. I then proceed to stack 19,999 pounds of gold ingots on top of the sheet of plywood. I then attempt to move the sheet of plywood normally.

Can an object under the effect of a 6th level immovable object spell still be moved normally while it is carrying up to 20,000 pounds?

Note, 20,000 pounds of gold is not very big in terms of volume. The density of gold is 1206 lb/ft3, so 20,000 lbs of gold would only be about 16 ft3, or a cube about 2.55 ft on each side.

dnd 5e – Is it possible to combine using heavy weapons and light weapons in this way as a monk?

Simply put, there is no reason why you shouldn’t be able to sheathe the dagger between the attacks of the Attack action, nor any rule that the Extra Attack has to be taken using the same weapon. If you want to use a similar technique on your next turn, you can attack with the greatsword first, then unsheathe the dagger and attack with the dagger.

Agile parry cannot be used as a bonus action:

If you make an unarmed strike as part of the Attack action on your turn and are holding a kensei weapon, you can use it to defend yourself if it is a melee weapon. …

You need to be holding your dagger (or another kensei weapon) and while making an unarmed strike as a part of your Attack action in order for the bonus to activate. If you use your Attack action to make two attacks with the greatsword, you have expended the Attack action without triggering Agile parry. However, you could attack once with the greatsword, unsheathe the dagger and perform an unarmed strike to gain the bonus, and follow it up with a bonus action unarmed strike attack from the Martial arts class feature.

The latter part, using one’s Action surge to gain an additional action, and using it to attack with dagger, sheathe the dagger, attack with greatsword and use Flurry of blows, is legal.

dnd 5e – Does the “great weapon master” feat give wizards the ability to use heavy weapons in Dungeons and Dragons 5e

Great Weapon Master does not grant any proficiencies.

First, if the feat granted proficiency with any weapons, it would state that it granted proficiency with a weapon. It does not.

Second, the clause you quote is defining the condition under which one may use the second bullet of the feat:

Before you make a melee attack with a heavy weapon that you are proficient with…

It states “before you make a melee attack”, then defines parameters for that melee attack, specifically, that it must be made with a heavy weapon you are proficient with. If you do not have proficiency with a particular heavy weapon, you may not use the second bullet of GWM while making attacks with that particular weapon.

design patterns – CQRS for avoiding heavy joins

I’ve been wondering about what is a perfect use case for CQRS where the benefits overcome the complexity and the cost with come with the package. So for me to better understand it, I want to share with you a theoretical use case and we can see together whether it’s a good CQRS fit or not, and if not what alternatives would be good in this case.

Let’s say we have the following very simple model:
Simple model
we can see, we have departments which have multiple students where they can pass exams on subjects which are classified into categories. Very simple.

Let’s also say our solution have a screen where we want to display all these information. Here’s our ugly UI for this page:

Our ugly UI

As you can see the information shown in the table must be extracted from all the entities shown above. So we have a lot of joins.

Supposing that our client have w very successful online school with millions students. And they do not tolerate performance issues, so the solution must be as fast as possible.

It’s clear that there are multiple joins when displaying this page, so to improve the overall readability we went ahead and started experimenting on CQRS.
We need to add a new database for read operations which stores all the above information in a single row, so the read model for our view is as follows:

enter image description here

This will definitively make reading faster but it will also make thing more complicated. For example, we need an event source to publish event that sync the read database with the write database, etc…

So my question is, in this particular use case, is CQRS beneficial ?

amazon web services – Which AWS cloud solution is best for moderately heavy scaled-out event processing (like Lambda, but for somewhat bigger jobs)?

We had some event processing being done with a cron job calling to a web API, but it turns out we need to scale this out, way out, because our event message quantity is growing, and the web API we have been using is reserved for realtime execution use cases. So we set it up with Amazon SQS queue being read into an AWS Lambda function, which scales out the processing. The problem that we’re running into is that the processing is not very small, there are seven or so tasks that processing entails including integration with S3, ElasticSearch, parsing and mutating data, custom web API invocations, SMTP/email, etc. Since these integration points involve related integration dependencies, the payload size just for deployment in a .zip file is more than 50MB, which exceeds the maximum size allowed for Lambdas. If deployed, it would take about 40 seconds to set up each instance and again as much to complete each message. Lambdas, we are reminded, are intended for really small, lightweight, “do it and quit quick” type of tasks, not moderately heavy handed processing, so I suppose Lambda was not the right choice for us.

It occurred to me that I could have the Lambda call the web API again, or call a new web API app just for this purpose. But then that web API would end up needing to scale up, not out. We want to automatically scale out, which Lambda gave us.

We know we could also chunk the processing into multiple stages so that Lambda is indeed staying simple, there would just be multiple Lambdas instead of one, but that would also mean more SQS/SNS queues/topics, and I am trying to avoid building a Rube Goldberg machine.

There are so many options out there that we can look at for running this processor but unfortunately so many of them seem like they will involve a great deal of hand-holding just for infrastructure/architecture setup, things like kubernetes (containerized packages), EC2 (VMs), etc. What is the best strategy for this problem?

Want to study Graduate Measure Theory with heavy Emphasis on Topology and/or Geometry.

I did one course in Measure Theory and want to study it again. But this time I want to do this in a way that emphasizes Measure Theoretic approach over Geometric or Topological Spaces. I don’t know, if it is at all possible. But I have heard there are some Differential forms and Measure theoretic relations on manifolds. So, my question is,-

  1. Do you know a graduate level literature (book,notes,lectures anything) on Measure Theory that you think is topologically or Geometrically heavy (in your judgement) ? Showing an interplay between Measure theory and topology/geometry is desired but any other reasons that you have is good too.

  2. More specifically, Is there anything for measure theory on manifolds?

  3. Is reading Geometric Measure Theory a good idea for this?

I asked this on Reddit too. But I need more opinions.Thank You.

cpu – Intel vcore heavy fluctuations

This is the processor – Intel® Core™ i5-8265U Processor

CPU-Z shows 0.6XX – 1.1XX for vcore changing constantly, more than a few times in second, the core speed also changes, and this is in idle.

When in power saving mode the fluctuations stay in the range of 0.640 – 0.670 most of the time.

I have another Celeron laptop, vcore and speed change there as well but way more stable, it would sometimes just stay stable at some value in idle.

Is this whole thing normal, can some other Kaby lake users share their experience?

dnd 5e – How far can you drag a grappled, heavy opponent

A mostly theoretical rules question. Assume a Medium creature (“Grappler”) has grappled another Medium creature (“Heavyweight”). For unimportant reasons, Heavyweight is very heavy- heavier than Grappler’s carry capacity, but not so heavy as to exceed Grappler’s push/drag/lift capacity.

The rules for moving a grappled opponent (PHB p.195) state:

When you move, you can drag or carry the grappled creature with you, but your speed is halved, unless the creature is two or more sizes smaller than you.

The rules for dragging a weight (PHB p.175) state

You can push, drag, or lift a weight in pounds up to twice your carrying capacity (or 30 times your Strength score). While pushing or dragging weight in excess of your carrying capacity, your speed drops to 5 feet.

If Grappler were to attempt to drag Heavyweight, in what order should these rules be adjudicated to determine how far Grappler could move?
