Like every boom/bust cycle, the "d20 bust" was what happened when the "d20 boom" ended. What's the d20 Boom? I don't know if that's an official term, but it's one I use because it works, and it fits the idea of a bust pretty well. If you look back to when 3.0 came out, it did an interesting thing that no game with it's reach had done before: it made it ...

Time Periods... Pre-OGL: Before 1999 OGL/d20 Era: 1999-2007 Boom: late 2000 to mid 2002 Bust: 2005 to 2007 Post d20 To Understand the Bust, you must understand the Boom When the Open Gaming License (OGL) was used on D&D 3.0 in 1999, along with the D20 System Trademark License (d20 STL), it ushered in a new era of 3rd party licensed supplements.This ...

You’re conflating several issues. There’s Dungeons & Dragons (in its various editions), the d20 System, the d20 System Trademark License (with associated d20 System Trademark Guide), the Open Game License, and System Reference Documents. You didn’t raise any concerns about it, but the Game System License is also a part of this story. The d20 System The ...

The usual way of doing a conversion between systems is to not try to reproduce the mechanics, but to look at what the mechanics are trying to accomplish or model and then figure out the "native" way in the new system for how that would be done. Since you're using D6 Fantasy, you're presumably using D6 Fantasy's combat system instead of trying to emulate d20'...

The most basic stuff – the fundamental core d20 system – is largely the same. That is, you still roll a d20 and add a bonus, and check against a number. Bonuses of the same type don’t stack. Various character options (races, classes, feats, class features, spells, items) are all new, even if they have the same name as a 3.5 option. I’m not going to go ...

The initial D20 boom was driven by two licenses: The Open Game License allowed third-party creators to reference and reuse a significant portion of the D&D 3rd Edition ruleset. This is, of course, useful for writing D&D3-compatible game content. The D20 System Trademark License allowed creators to actually label their products with the D20 System ...

The d20srd FAQ appears to answer this for us, rather helpfully, in a question about future content: This site currently contains content from all sourcebooks published by Wizards of the Coast that contain open content. This includes open content from the following books published in the official d20 SRD: Player's Handbook Dungeon Master's Guide ...

Looking at D6 Probabilities with the Wild Die, If you're going to be purely technical about it, it's trivial to figure out the odds of success on a skill check in D&D assuming a set of characters with skills: $$\frac{1-\left(\text{difficulty-bonus}-1\right)}{20}$$ Therefore, assuming DC 10, and a bonus of 4, the above returns .75. For a strict ...

You're going to trivialize stuff intended for lower levels, except in the case of failure. The particularly worrysome one would be something like traps, where the consequences of failure are based on HP and saves (both of which you didn't scale up). To provide any chance of failure to find/disarm a trap for a character with level 10 skills, you're going to ...

Fundamentally, you'll remove opportunities for advancement on the skill side of the character up to level 10. This will make combat, saves and feats the only options for expanding capability through the game. It will also make your players ability to predict the game at character creation even more important than usual. The biggest benefit to the game is ...

Yeah, the d20 version of Call of Cthulhu is pretty complete. It has a stat block for a demigod version Cthulhu on p.292. You likely don't want to fight Cthulhu himself however... Try on this CR 20 Starspawn of Cthulhu (a mini Cthulhu) for Pathfinder. Cthulhu himself is more of a god, no stat block. Update: Cthulhu himself is now found in Pathfinder's ...

The rules The answer is no, there are no shields granting cover on its own and allowing to bash with them. Having such a shield would destroy the balance because tower shields would become obsolete in the face of a shield that does both and heavy shields would be at least challenged, depending on your playstyle. I am also not aware of any official ...

Is this the game you are looking for?: The Arcanum or Atlantis

You would break things. Many prestige class prerequisites, for example, are based on a number of ranks required in a certain skill, without it you'd be looking at PCs with level-inappropriate abilities and abilities that display erratic behavior. Balance aside, you'd be cutting away a significant portion of what you gain from level-ups, and level-ups are a ...

No, there is not. Generally, “checks” (ability checks, skill checks, initiative checks) do not have critical effects, and there are some very good reasons for that (5% failure rate is inappropriate for most of them, plus in many cases what would happen on “auto-success” is very unclear: take Jump for example). Natural-1s on saving ...

Here's the thing about the OGL. You don't actually need to use it just to reuse unpatented game mechanics. What the OGL does is provide what's known in legal terms as a safe harbor, in return for accepting restrictions on your reuse of mechanics. That means that as long as you follow the terms of the OGL, they agree not to throw lawyers at you (and ...

Yes, quite simply because nothing says he cannot. The artificer’s Item Creation ability defines a new use for Use Magic Device unique to that class, but nothing else about the check is called out as different from the way the skill generally works. Any and all bonuses to it apply. Furthermore, the Eberron Campaign Setting says that he makes items using Use ...

Yes, the D20 Future line includes Open Game Content (OGC) starship rules. You can get the official Starships SRD in charmingly-2000s Rich Text Format direct from Wizards of the Coast, or you can get them in convenient, futuristic HTML from a variety of online D20 Future SRD repositories, such as these: Starships at D20 Resources; Starships at DM Reference. ...

The DM typically determines if a creature's routed In a core-only Dungeons and Dragons 3.5, campaign there are no morale rules. Creatures fight to the death if the DM thinks they would and opt to flee or surrender if the DM thinks they would. This can be problematic for the DM and players alike. For example, a beginning DM may not realize exactly how ...

Tormenta is both an RPG system and a campaign setting The Tormenta article isn't about a specific book or book line, it's about the setting that is found within the books. Notably it's not an article titled “Tormenta RPG”, the article is just titled “Tormenta” (no italics), and the article confines itself to information regarding the setting's existence. ...

Well, first of all, this thread is all about the concept, starting with a variation on the katanas are underpowered in d20 meme. Several posters are unimpressed with Cthulu’s accomplishments as described in Lovecraft’s novels. This leads me to point out that the reason Cthulu was terrifying and dangerous in Lovecraft’s work is because he ...

This is probably right by the rules, but I think focusing on the rules issue is missing the real problem, which is one of communication. Whether or not you knew whether the rules support this, a Togorian Elite Soldier almost certainly would know if this would be sufficient to protect the girl. Without being there, it's a little hard to guess exactly how ...

Heroes of Battle has a system of rank and awards (along with benefits) that may suit your purposes. Additionally, the rules for Organizations may give you another option for 'keeping score' of PC accomplishments and incrementing rewards. Page 89 of Heroes of Battle: Decorations Every army has a different system of decorations, from the simple (...

No, from 3e onward there are not morale rules in the core books. Everyone shouts "DM decides" when this comes up, but I like to decide what I want to decide and what I want to randomize. (You may as well have the same fiat-vs-roll argument about everything from random encounters to hit rolls. To me it's easier to have a way to randomize it and then overrule ...

In 2004 during the d20 boom Mongoose published under the Open Gaming License the Mongoose Pocket Player's Handbook and the Mongoose Pocket GM's Guide, which, combined, were, essentially, the d20 SRD minus, I think, the monsters. An RPG.net review of the former is here.

You are thinking of the En Route series in the Atlas Games Penumbra/d20 3e-compatible line. There are three of them with about 20 encounters each. The first, En Route, has the carnival and pixie dance you mention. En Route II: By Land Or By Sea and En Route III: The Road Less Traveled are the sequels.

If you want the scenario to play out exactly like you're imagining, the Dungeons and Dragons 3.5 5th-level Sor/Wiz spell watchware [abjur] (Unapproachable East 53) does pretty much precisely what you describe. The spell's cast on an object and When that object is damaged, moved, or touched at any later time, you are instantly aware of the fact. If another ...

In order for this to work, you nearly have to assume only automatic ability progression (or a headband of intelligence, if it's on their sheet) could be used to increase Intelligence. It "works" otherwise, but you'll have no way to verify your conclusion. A lot of math. First, you know the amount of skill points they have. You also know their current Int ...

D&D 3.0 and 3.5, though these inspired later editions. The article d20 System Definitions: Frequently Asked Questions, published by Wizards of the Coast in 2001, defines "d20 System" as follows: Q: What is meant by the term "d20 System"? A: The term refers to the game engine used in Wizards of the Coast's hobby gaming roleplaying ...

Yes, that is precisely it. The Heavy Load column on the Carrying Capacity table indicates how much your character can carry and still move about for long periods of time, even if his reaction time is slowed down and he cannot run. The maximum Heavy Load is his maximum load. In the Player's Handbook this is made clear in the first paragraph on page 162, ...
