What happens if we get rid of opportunity attacks completely?

Opportunity attacks have their long way in the world of tabletop games and D&D in particular. 3.5e/PF both had an exhaustive list of actions which can or can not trigger an OA.

5th edition simplified things a lot. One single trigger left:

You can make an opportunity attack when a hostile creature that you can see moves out of your reach.

It seems the developers consider this particular trigger as the most important one. So what happens if we remove it?

The reason I ask is because there are 5e-based games which does not have OAs at all (Five Torches Deep, for instance), so I want to know, how a typical 5e gameplay change if the DM introduces “no opportunity attacks” house rule (assuming we play without OA-based feats).

How can I raise concerns with a new DM about XP splitting?

My wife is new to DMing and D&D as a whole.

We had our first game yesterday and one of my friends raised a concern about how she was awarding XP as she was giving the XP to the person that got the killing blow. He felt, and I agree, that this was unfair to the people playing a support role i.e. our Bard and Druid.

Any suggestions on how I should bring this up without it sounding like a criticism or that I’m trying to take over?

When do spells expire?

When casting spells with a duration longer than instantaneous, at what point in the round does the effect expire?

Say, for example, you cast a spell with a duration of 1 round. Does that mean the spell ends at the end of your turn? Or at the beginning of your next turn?

I’ve checked the SRD and can’t find anything solid that clearly explains when the effects of spells run out.

Can I sell a supplement that references non-SRD Cleric Domains?

I am creating a completely unique setting for Dungeons & Dragons 5th Edition, and really pouring my heart and soul into it. Under Wizards of the Coast’s OGL (Open Gaming License), I am hoping to sell this setting as a supplement book (probably a downloadable PDF through DriveThruRPG).

However, I’m a little bit fuzzy on the differences between the OGL, and the SRD, and what I’m allowed to use vs. what I’m not in the context of a commercial product. Specifically, I was thinking of referencing some non-SRD cleric domains (the only SRD cleric domain, as far as I know, is Life), such as, say, the ones from the Player’s Handbook, in the context of locations that are tied to particular Domains. Would that be permissible? I don’t know if I’m allowed to use non-SRD domains in a commercial work. I wouldn’t be reproducing the actual Domains, in their specific mechanics, just referencing their existence.

Psychic Scream – Healing after your head explodes?

By request I’m DMing an adventure with a lot of H.P. Lovecraft overtones, and the party has encountered the Big-Bad-Guy tentacle horror, a twenty foot Obyrith I’ve styled after the Far Realms Glothoma. It’s nearly out of hit points, and I’d like it to cast one final spell without a TPK, but I’m worried I’ve chosen the wrong one due to the flavor text.

The description of the psychic scream spell (Xanathar’s Guide to Everything, p. 163) states:

Each target must make an Intelligence saving throw. On a failed save, a target takes 14d6 psychic damage and is stunned. On a successful save, a target takes half as much damage and isn’t stunned. If a target is killed by this damage, its head explodes, assuming it has one.

Could someone parse this out for me? If a character takes enough damage to hit zero hitpoints, are they “dead” as far as this spell is concerned, suffering the homage to the movie Scanners, with the full head popping effect — or is dead only dead when they either fail enough death saving throws, or die instantly from the Massive Damage rule?

I ask because despite having two war clerics in their party, they’re only level 6, which means the best they can respond with is revivify – which can’t restore missing body parts:

You touch a creature that has died within the last minute. That creature returns to life with 1 hit point. This spell can’t return to life a creature that has died of old age, nor can it restore any missing body parts.

Warforged Psionic Monk / Frenzied Berserker / Occult Slayer

I’m building a specific Warforged. It will be permanently a large sized character: Dragon Magazine #150 “Arachnid Chassis”, plus “Scorpion Brand”, and “Iron Toothed Girdle” from Dragon Magazine #341. Also to complete his build he’s got two grafts from the Muag out of the FF 213-14 book they’re the “Shudder Plate” , and the “Stone Spitter Box”. Which begins my first question, in light of the Scorpion Brand’s stinger damage being (Fort. DC 14 initial and secondary 1d6), would the damage from a (Stone Spitter Box) be much worse (+1 on attack / 1d6 or 1d8 increased dam. 6* per day)? Be informed that the character will already possess two additional Stone Spitter’s on his shoulders. They’ll be constructed with the psionic weapons enhancement “Power Storing”. So to ask the question again, does the Stone Spitter’s damage out way the Scorpion Brand’s stinger, and two do you feel like it’s redundant to place another Stone Box on him in the first place? He’ll likewise be equipped with “The Jaws Of Death”, and “Battlefist”, now since he is going into a “Psionic Monk” roll. I’m thinking 2-3 levels of “Monk”, question #3 “Ardent” or “Psionic Warrior”? For how many levels because I still want to fit “Juggernaut”, “Occult Slayer” 2 of “Barbarian” and if I got anything left I want “Frenzied Berserker”. Forth ?, Do all of my grated weapons become apart of my natural attack since they are technically apart of my body? Like the one leg attack from the “Arachnid Chassis” ? By the way I would wrap said “Leg and Battlefist” with rags of “Mummy Rot”. Now all of this wouldn’t be possible without his mentor the small sized “Warforged Scout” riding on his back in a Psionic “Deep Crystal” capsule. His profession is an “Psionic Artificer”. Epic levels, his body is made of a “Psyforged Body”. His responsibilities to keep them running. So all of the big guys weapons, repairs, etc. are covered from this stand point. Hence the Psionic weapons enhancement on the Stone Spitter’s box or Stinger if you will. More so his Leg, Jaws of Death, Battlefist, Iron Toothed Girdle. Will be deadly for anyone. Please, let me know an answer to my questions? I’d greatly appreciate them. I’ll come back in the future to put finishing touches on the concept i.e. further enhancements for his other natural weapons. So on and so forth.

Casting spells using the Book of Ancient Secrets

I am playing a 3/3 Divine Soul Sorcerer/HexBlade Warlock, and have just chosen the Pact of the Tome, along with the Book of Ancient Secrets.

I have found a spellbook with Identify, which I am now transcribing into the book. I also have Unseen Servant as a known spell. I create a scroll, using the Arcana skill. And then use the scroll to transcribe the Unseen Servant spell to the Book. The Scroll is destroyed in the process. So far, so good.

I then replace Unseen Servant with Charm Person on my list of known spells.

Can I still cast the Unseen Servant as a ritual from the book?

Can I cast the Unseen Servant as a spell, using the book and a spell slot? This question arises from the interpretation from the text “You can’t cast the spells except as rituals, unless you’ve learned them by some other means.

If this is possible, it basically means I have an external memory extension, that when held, allows me access to cast any of the entries as a ritual.

And cast the spells that previously were known spells from my spell list that has been transcribed into the book, as spells, using spell slots.

Handing a weapon to another player during combat

The players in my game recently came across a fairly powerful magic sword as the first magic item they found. Shortly after that, they wound up in a boss fight.

The players came up with the ingenious idea of having one player attack with the sword, then hand it to the a nearby player so they could attack with it too. At the time I ruled that passing an item to another player would take an action, so they couldn’t do that.

But now I’m reviewing the rules and on pp. 190 of the PHB, it says handing an item to another character is “the sort of thing you can do in tandem with your movement and action.” Does this mean it’s possible for the PC’s to surround an enemy and just pass the sword down the line (in initiative order) so that each one can attack with the same magic sword? That seems over-powered, and a kind of ridiculous way to narrate a combat.

Ready actions: Can you knock someone prone?

Could you ready the action: If an enemy attacks me then, once they’ve attacked, I will attempt to knock them prone.

If so it could be used if the distance between you and an enemy was too far to cross in one move, moving to 30 feet from them. Readying this action would give you advantage on your next attack, if successful, because the target would still be prone (not having had their turn yet to stand back up).
