This spell is more powerful than almost any other spell in 5e, and thus should not be allowed in its current state With the exception of wish, this might be the most powerful spell in the game if implemented the way you have it right now. If you had to pick a spell level right here and now with no modifications make it 9th level because that is the highest ...

Maintaining the AD&D Feel If you want to maintain the AD&D feel of this module you have to keep the following in mind: it's a death-trap. I have played it, I have DMed it and I have spoken to many people who fondly remember the way their characters died in it; I have never spoken to anyone who finished it although I and a few others have escaped ...

Although the CR / encounter XP / difficulty numbers in the DMG are not infallible, they are useful as general guidlines. Lets take a look at the giant encounter! Stone giants (MM 156) are CR 7 / 2900xp alone. Looking at DMG 82 (all information here is from that page) we see that if you have more than one monster in a fight, there is an xp multiplier, in ...

Frame challenge ahead (you have been warned)! if the bad guy can do it then so can the players, given enough time and resources. This is a very un-5e thing to say - it looks very 3e to me. 5e makes it clear that monsters/NPCs are not like PCs and that they can do things that the PCs cannot do and vice versa. The NPCs in the Monster Manual are impossible ...

Yes you can: it has now been published as a D&D 5e module. Tomb of Horrors is one of seven modules from previous editions recently released in "Tales From the yawning Portal" published by Wizards of the Coast for use with the D&D 5e system. All of the monsters (save one, see spoiler) are either in the book, or in the Basic Rules downloadable from ...

At the risk of answering the question before it has been clarified... No. Seriously, you have several uphill battles: Classes/levels versus skills and advantages/disadvantages -- leveling up is very different between D&D (leveling up gives new prescribed powers and increases hit points, generic base attack bonus, and certain saves) and GURPS (where ...

Consider using the Infestation cantrip from Xanathar's Guide to Everything From the spell: You cause a cloud of mites, fleas, and other parasites to appear momentarily on one creature you can see within range. Simply reflavouring this spell as Bees could easily achieve the effect you're looking for, in addition to dealing some damage and making the ...

I don't know if the V:tM players are familiar with D&D/PF, but if they're not, it would be a bit annoying for them to have to learn the rules, and it would put them at a disadvantage (enjoyment-wise) by the other players. What I think would be best for a one-shot game aimed more at creating nostalgia and memories is to use a system that none of the ...

It's most likely too strong and inherently problematic It deals a lot of guaranteed force damage Let's compare the level 6 version to a spell that's pretty similar, Disintegrate. They are both spells that deal a lot of force damage and not much else. (Ignoring the fact that Disintegrate will...well... disintegrate stuff.) Disintegrate allows a dexterity ...

Don't Do It I'm planning on making a D&D 5e campaign for my friends so they can experience what an okay DM is like If this is your goal, then keep the game simple. Attempting to add all those disparate elements is going to create confusion. Show them the game straight and clean, earn their trust and help them understand it. Don't run outlandish high ...


22

You're in luck, because the power levels of the old Basic D&D games are similar to those of 5e.* I'm going to illustrate my answer with examples from B5 Horror on the Hill, but you can apply the principles to any of your Basic D&D Modules. 1. Replace what monsters and NPCs you can from the 5e Monster Manual This will save you a lot of work, and ...

Subduing in 1st Edition In AD&D (1st Edition), the rules for subduing a dragon were found in the Monster Manual I, under the DRAGON entry: Subduing a Dragon: An attack on a dragon to subdue, and thus capture it may be opted for if such intent is announced in advance of the combat. Silver, gold, chromatic and platinum dragons cannot be subdued. (...

I see two broad options, one of which is a bit of a frame-change. First, the frame change: most undead - especially low-level undead like zombies and skeletons - were mindless in previous editions of D&D and aren't terribly bright in 5E. It shouldn't be too hard for some passably persuasive denizens to convince the undead hordes to follow their commands ...

Make a high level wizard that behaves as a low level wizard There is one characteristic about wizard that are common through every D&D game, they are extremely squishy, especially if they are badly built or they used all their spells before a fight. A wizard without spells is not different than a level 1 fighter with more hp, maybe better to hit chance ...

Using Infestation is definitely a good idea, but if you insist on making it a spell of its own for comedic effect, I would personally do something like this. Summon Bee Conjuration cantrip Casting Time: 1 bonus action Range: 10 feet Components: V, S Duration: Instantaneous You summon a single honey bee from the nearest hive. The bee appears in a location of ...

You probably could, but you don't really need to. D&D 5e has rules for sailing on pages 117-119 of the Dungeon Master's Guide.

NPCs don't have classes Only PCs have classes. NPCs have a statblock that fully encompasses everything they are capable of. They may have features in common with PC classes, but they may have extra features a PC cannot replicate, or be lacking features that a similar PC possesses. Referring to the Basic Rules for 5E (replicated in the Monster Manual) we get ...

Your best bet is to rebuild the hazard from scratch using the 5e rules. Wizards, when they first published 5e, also released a handy Conversion Guide, with details about converting characters, monsters, magic gear, and even entire adventures. There are two types of conversions listed, Careful and Quick, and both suggest utilizing the new Trap rules from the ...

The simplest solution I have found whenever I need an NPC to be able to act outside of the normal rules governing their class and level is by the expediency of a customized magic item. As a matter of fact, I have recently used exactly this sort of magic item to solve exactly this sort of problem. I needed a medium level NPC to have the potential of leading ...

The general conversion method is, find similar races & classes in 5e, and create a character from scratch, using them. There are many differences between 3.5e and 5e. Since PF is based on 3.5e, there are slightly more differences from there to 5e. So, there is no easy conversion method.

Wizards of the Coast Released a PDF on this topic In the October 2015 Rules reference, WoTC released a PDF that was designed to help the conversion of older editions to 5e; both monster statistics and adventures/treasure. The PDF can be found here The document includes the following quick conversion rules about monster statistics from first and second ...

Conversion is hard. Converting characters/monsters between editions is hard. Converting between 4e and 5e is especially hard. One of the primary focuses of 4e, if not the the primary focus, was tactical combat, so 4e has a lot of special mechanics to support that style of play. Because 5e sort of supports tactical combat but certainly doesn't emphasize it, ...

Pick the classes and races that best capture those characters to you. It seems to me you're having trouble because you want to make sure you do them the right way, but there isn't any one right or best way to do them. Last year, we broached the topic of how to build Gandalf in D&D 3.5e. BESW summarised the problem with this quite well in his answer: ...

You basically can't For a simple comparison: the D&D 5e Tarrasque has 25 AC, 3 more than the second best AC monster. PF's Tarrasque has 40 AC. Due to the bounded accuracy of D&D 5e your players won't get near the extremely high modifiers of Pathfinder; at lower levels you might use monsters as-is (remembering that they'll be way stronger on 5e ...

Mechanically, Pathfinder 2e is a completely different system. Even the things that share the same name are different enough that you can use basically nothing from 3.5e or Pathfinder beyond the ideas themselves—all the numbers, effects, conditions, costs, and so on are going to have to be redesigned from scratch for 2e. Narratively, Pathfinder 2e has ...


15

Run one-shots. I would heavily advise against trying to blend game mechanics from two different systems together, aside maybe from AD&D which at least shares a rough power parallel. You can't run Monster of the Week enemies in D&D because Monster of the Week enemies don't have actions and do whatever you want. You can't run Honey Heist enemies ...

It's important when tackling this to notice that D&D Next saves' math are tied to the effect, while AD&D saves math—despite the names being that of effects—are actually tied to class and level. That means that there's no way to crunch the AD&D math to find a conversion formula—the numbers are representing different things. As ...

Chris Perkins adapted Tomb of Horrors for D&D Next in Dungeon magazine, issue 213. D&D Next was sort of the "beta version" of fifth edition, but it should be very usable.


14

Unfortunately, you can't. 4e and 5e have wildly different mechanics. Furthermore, 4e and 5e character creation processes will produce characters with very different average ACs, attack bonuses, and hit point totals. There simply isn't any way to use a 4e character in a 5e game; the best you can do is attempt to create a new 5e character based on the 4e ...

At least 9th, definitely above 8th This spell is strictly more powerful than the 8th level spell, Power Word Stun: A creature you can see is stunned if it has 150 hit points or less. Otherwise, nothing happens. The target can make a Constitution save at the end of its turns, being freed on a success. Power Word Stun is effectively a free stun for 1 ...
