Earlier this year my online ‘London D&D group’ got back together for a new campaign, with my friend Mike taking up the reins as Dungeon Master. The story so far is that our party has been recruited into a dissident faction which is dedicated to fighting slavery in the autocratic, tiefling-run state that constitutes the campaign setting.
In a recent session, we accepted a mission to execute a known slave trader in a foreign city and settled on ambushing the orc in question when he was out on the streets on business with only a couple of bodyguards. A combat ensued, and, winning initiative, our green dragonborn paladin decided that round one was the optimal time to unleash his breath weapon. Given it’s a new character, the player started scrambling around for the precise breath weapon rules. As he manoeuvred his dragonborn on the grid, to line up the potential targets in a neat row of less than 30 feet, he declared that his targets must make a Dexterity save or take 1d10 poison damage. The Dungeon Master, somewhat confused, said he believed it was a cone area of effect and that, if it was poison damage, surely it would be a Constitution save? And he started looking up the rules himself. After a fair bit of toing and froing, the player cleared up that he was citing the ‘new’ dragonborn breath weapon rules from Fizban’s Treasury of Dragons and not from the 2014 Player’s Handbook…. which was the tome the DM was reading from.
At this point, I was tempted to pull out my brand new 2024 Player’s Handbook and read off what these sparkling new rules had to say on the matter… before common sense told me not to prolong the palaver that was had already effectively halted this ‘exciting’ combat before it begun.
While indubitably an issue to be filed in the “1st world problems” drawer, this scene brought home to me that, in 2024, Dungeons & Dragons exists in a state of rules ambiguity.

It’s simple… just check all the editions, and then choose the most powerful option! (Art by WOTC).
We now have two official (and allegedly compatible!) Player’s Handbooks in play, as well as official rules from tomes like Tasha’s Cauldron of Everything and Fizban’s, whose niche updates are considered to supersede 2014 rules (but presumably not 2024’s). While anyone who read all the UA playtest material might also have abandoned rules and misconceptions rattling around in their brain (wasn’t the dragonborn breath weapon a bonus action at some point!?). And these are just the D&D rules released by WOTC, and don’t of course factor in any house rules that have garnered popularity in the community, or specific tidbits DMs might have imported from the ever-increasing number of 5e clones and competing systems.
Playing a swarmkeeper ranger from Tasha’s, in this new campaign, means I have noticed this web of conflicting rules quite acutely… because, in addition to my subclass features, I also gobbled up Tasha’s improvements to the ranger core class, making Tasha’s an important reference for me. But I still have to dip into to the Player’s Handbook for those core class features that remain the same. And which PH should I use by the way…? I would love to start trialling the 2024 rules, but as the only person on the table with them, I guess a) I need my DM’s permission and b) doing so would be unfair on the others, as there’s some unapologetic class power creep when comparing the two rules sets. (To add to my overall confusion, in Mike’s previous campaign a different player had used the Pagnabros ranger fix, championed by Dungeon Coach, meaning I have echoes of unofficial ranger features ringing in my head, as well as the rules from three different official books). Meanwhile, it’s not only my class features that are published in multiple books. Different versions of the hobgoblin racial, sorry species, traits are published in Volo’s Guide to Monsters and Mordenkainen’s Monsters of the Multiverse, creating more ambiguity.
There was a relatively long period of recent D&D history where all the current official rules were included in one book (let’s say 2014 up to 2020, when Tasha’s was published), and, after a bit of getting used to them and interpreting the lauded (but to my mind quite irritating and opaque) ‘natural’ language of the 2014 Player’s Handbook, pretty much everyone I played with was on the same page with regards to how the game worked, with the only difference being a handful of house rules per table.
I would say that’s certainly not the case right now… and I wonder if D&D ever will reach that level of commonality again?
It depends on a few factors I guess… such as the willingness of the vast majority of the 5e D&D playing community to invest in the new core rulebooks, and their subsequent decision on whether to make the 2024 PHB their de facto rules reference, or whether to keep any parts from the 2014 edition they prefer.
For the second to happen, I suspect that the 2024 rules need to prove that they are better overall than the 2014 set. In other words, have they fixed more old broken things than they have introduced new broken things? I have my doubts.

Introducing one universally used reference book…
Anyhow, hopefully I have time to dig into the new PHB a bit more over the next weeks and can perhaps write a little post to see if the 2024 rules managed to address the issues I wanted to see fixed in the latest edition.
Exciting New Project!
The eagle-eyed amongst you might have noticed I’ve been posting somewhat infrequently lately, which given all the stuff going on with D&D is somewhat strange timing. However, I have actually been commissioned by a US publisher to write a 200-page RPG book and naturally that is taking up a fair bit of my time. I won’t reveal much more now, but I will say its a system agnostic toolkit that I think virtually every GM under the sun will be able to get plenty of use from… so stay tuned for more news in early 2025! And, if you don’t see so many posts during the remainder of the year it’s not because I’ve quit gaming or anything. Rather the opposite, I’m going deeper, and with a bit of luck my future involves a lot more RPG writing, chat and product creation! (Ps. I do still plan to keep updating the blog… but there’s a chance it will have to take a backseat for a few months!).

Of course I am excited to see your new work!!
Oh right, the article! Yes, I totally agree with your commentary and frustration. We just ended a session of my D&D game, where I got confused on which version of MY OWN house rules we were using (having added, tweaked, and discarded literally pages of them over time). Ironically, we were using the “simplified” version, which I had forgotten.
Add to that – like you said – one player was using a modified ranger, two players are using Exploit Dice from llaserllama’s excellent class rewrites, and my campaign setting has some heavy flavor-based tweaks on how I describe the different “Power Sources” (4e term for “Primal” vs. “Arcane” vs. “Divine” magic)… confusion abounds. And we use UA’s 10-level exhaustion rules. So far no one has added in the 2024 rules… but the bard player did ask if his Healing Word spell had been upgraded to double dice yet! (After being hit by the 38pt Cone of Cold, he was eager to get some additional dice of recuperation!)
I think the only thing we can do, for my player group, is collectively decide “No backward compatibility.” Either we play as is with no 2024 rules, or we play only 2024 rules and discard all the previous variants… ick.

Hey Rick
Yes, I think I watched a Sly Flourish vid where he said the worst thing about House Rules is that they make things harder to remember… and I concur on that point. I like and use several House Rules, but since players don’t really remember them or have easy access to them (unlike the PHB), the DM has to really enforce them by themselves. They also constantly change as we refine them, so are even harder to remember.
With two sets of official rules now I think everyone is going take bits from one and bits from the other, and also feel more empowered to make house rules…. because even the official rules don’t agree, what’s the difference if I change things around a little, right?
I agree with you that DMs should at the very least use one of 2014 or 2024 as a base. And then state what the exceptions they are using from the other set of rules.
My in person Barcelona group features a pool of about 8 players, (nearly) all of whom own a copy of the PHB 2014, and none a copy of the 2024 rules. I might slowly start importing one or two bits from 2024 as house rules… but probably the right time to switch – if ever – will be at the start of a new campaign.
Cheers!

We’ve had two sessions now since this post. We decided last session to use the 2024 spells in toto, with no 2014 holdbacks. This resulted in a couple nerfs (the warlock is hating on “Chill Touch” now being *touch*!), a couple upgrades (the bard’s “Healing Word” is 2d4), and a couple of “lateral moves” (Bladeward is now an attacker roll penalty, not resistance). Not that they’ll ever have access to it, but Power Word Kill now does damage if it fails to kill you – a house rule we already had, and can now throw away. Our 3-page custom Counterspell rules are awesome…. and we’re okay with dropping them in favor of the new save-based spell, just to save memory-space.
Between-session conversations I think are bringing us around to “use the 2024 Feats, in toto”, although there are more consequences to this choice. Since the players are 8th level already, there’s no backward retcon of “sorry, you can’t have this feat as a 1st level human”… although at least two PCs are thus no longer “legal”. On the flip side, though, the bard now gets to pick a new feat because “+2 CHA @ 4th, Inspiring Leader at 8th” now is “Inspiring Leader at 4th with +1 CHA; (insert feat name here) at 8th with +1 CHA”. The Rogue’s Mobility feat got sorta-nerfed (disad vs. all opportunity attacks instead of 100% immunity to one… but now with +1 DEX!) The fighter/mage’s Warcaster feat got buffed into a loophole – and he agreed to voluntarily forgo the loophole.
So we’ll give the 2024 rules on feats and spells a couple sessions and see what breaks out. The Fighter and Rogue are also trying out Weapon Masteries… but have to forgo their llaserllama Exploit Dice when they do so. The Warlock is not rebuilding his class at this time. The Bard is. The Fighter/Mage/Rogue is not (he loses a skill due to the way lockpicking changed). The Rogue/Druid is changing Rogue to 2024, but not Druid (she is Druid-2, and would lose her thematic subclass).
Stay tuned!
Mike
Poison gas clouds should definitely be a Con Save. The PHB Dragonborn did need improving but no need to tinker with the bits that don’t need fixing.
It’s particularly confusing when players have books the DM doesn’t have. They are all on my wish list but nobody buys them for me. ;(

We have several DMs in my regular group-one is firmly keeping to pre 2024 stuff in his campaign, having felt like he just got to know them, and the rest of us older timers are incorporating the new ones and learning together as we go. It’s kind of nostalgic!
I think only time will tell, but I wouldn’t want to toss any of the wonderful accompaniments the 2014 rules had such as Tasha’s and whatever else. House rules I tend to write out in soft stone for my campaign, so honestly I already know that, for my table at least, we’ll take what we like and ditch what we don’t in a frankenstein almost homebrew sort of way I’ve always done things.
