Wasted Lands: The Dreaming Age - Class Abilities in O.G.R.E.S.

Class Abilities - Powered by O.G.R.E.S.

In previous blogs we've looked behind the curtain at what the O.G.R.E.S. system brings to the table for your fantasy game, whether it is a retroclone or something different, and how features such as Divine Touchstones, nonhuman Species and cultural backgrounds, and Tiered Attributes work in the game. The most recent blog with Tiered Attributes took a look at the ability check mechanic, which functions by rolling a d20, adding applicable bonuses and trying to get a 20 or better. 

This blog will look at how class abilities work in the O.G.R.E.S. system. For those who are familiar with old-school gaming, it should look quite familiar, though with a few twists to better codify and unify the mechanic across the board. For those who are new, we'll also look at why we chose a separate mechanic for the class abilities rather than sticking with the d20 check.

Class Ability Mechanic

The class ability mechanic in the O.G.R.E.S. system is quite simple - a straight percentile roll attempting to get equal to or less than your score. Thus, if you have a 50% chance to accomplish something, you roll percentile dice, and a 0 to 50 succeeds. In many cases, the base percentile chance is adjusted up or down, usually in 5- to 10-point increments, based on the difficulty of the task. From behind the screen, the GM can set a level of difficulty, multiply that by 5, and apply the result to the base chance of success. 

The GM may decide, for example, that a Warrior attempting to track a quarry through the wilderness sees their chance modified by the difference between the Warrior's level and their opponent's. If the Warror, then, is level 5, and the opponent level 8, there is a 3-level difference. Multiplying these 3 levels by 5 results in 15, so the Warrior's Tracking ability is reduced by 15% for this check. 

On the other hand, if the Warrior is higher level than their opponent, their chance may increase by a like amount - a 5th-level Warrior tracking a 2nd-level quarry would improve their Tracking chance by 15%. As with Difficulty Bonuses in attribute checks, the GM may or may not choose to tell the player what the difficulty is; they may merely say, "you succeeded," or "you failed." 

This does not mean, for example, that you cannot try something that is not a class ability. Consider a Renegade attempting to sneak up on a target. Other characters in the party may also attempt this. The Renegade rolls their stealth ability. Other characters make an Agility check. 

The difference is that if the Renegade fails their stealth ability, they can still attempt an Agility check. They essentially get two shots at it. In addition, the Renegade, if they succeed, is assumed to be absolutely silent and undetectable. Other characters may still have to beat an enemy's Wits save, or suffer a "rule of 2" check even if they succeed.

Spellcasting in O.G.R.E.S.

The class ability mechanic in O.G.R.E.S. even applies to casting spells. O.G.R.E.S., unlike many old-school games, does not use a so-called "Vancian" or "Fire and Forget" magic system. Rather, the caster has a base spellcasting percentage which like all class abilities improves as the character goes up in level. This percentage is then modified downward by 5% per level of the spell they are casting. A first-level spell, then, reduces casting by 5%. A fifth-level spell reduces casting by 25%. 

So long as you do not fail a casting roll, you can continue to cast spells all day long. If you do fail a casting roll, your spell backfires in some way, requiring a check on a spell backfire table to see how badly it blows up in your face. You may lose access to the spell until the next day. You may have no ill effects except a spell failure. You could summon a horrific demon from the depths of the Underworld that instantly attacks you. It all depends on the power of the spell you were trying to cast, and your result on the table. 

The rationale for applying the class ability mechanic to spellcasting is to keep it unified with the rest of the class abilities. In old-school versions of games, the mechanics used in O.G.R.E.S. are all baked into the system - rangers of old used percentile dice to track. Thieves of old used percentile dice for their stealth abilites. The same goes for their comparable classes in Wasted Lands. Spellcasters, however, always and inexplicably used a completely different mechanic for casting spells, and stand alone for that. We took the opportunity to unify magic users, psychics, and the like so that their abilities function the same as any other class'. 

Why Two Mechanics?

We live in a world of game design where unified mechanics rule common wisdom. There is nothing wrong with unified mechanics, and indeed, Wasted Lands offers guidelines to convert the entire game to whichever type of unified resolution system you like - d20, percentile, or even dice pool - all without changing the stats. We also include the return of the O.R.C.S. system that powered Spellcraft & Swordplay if you prefer that approach. So you do have the way to truly make the game your own. 

The idea behind using more than one resolution mechanic is that there is an elegance to the mechanics both fading into the background while you play, while at the same time giving you an instant insight into what is going on at any given time. Consider the all-too-common scenario of the players paying half-attention at the table when the GM tells one player to make a roll for something. 

Suddenly the entire table comes to life with everyone asking, "What's she doing? Can I make a roll, too?" 

In this case, if the roll the player makes is percentile-based, the other players immediately know that it's class-ability-related, so they have a better chance of succeeding than anyone else. It lets you know when a character is digging into the area of expertise where they shine. 

Skills in O.G.R.E.S.

By default, the O.G.R.E.S. system seeks to keep things as simple and straightforward as possible, so skills are not an essential part of the system. They are, however, included as an optional subsystem that allows you to give characters a bit more definition regarding what they can do and what their knowledge is outside of their character class. Skills, essentially, work like any other class ability, which means they use percentile checks, modified up or down in 5% or 10% increments based on the difficulty of the task at hand. 

That's all for today! Stay tuned for more behind the curtain looks at O.G.R.E.S. as we go on, and be sure to hit up the Kickstarter and sign up to be notified when we go live!

The Darkness Spell in 5e is Pointless

Image
 Here's a fun observation. The spell darkness, in 5e, has absolutely zero mechanical effect in 5th edition D&D. Darkness creates a heavily obscured area .  Creatures within that area effectively suffer from the blinded condition. Blinded characters suffer disadvantage on attacks, and creatures attacking them have advantage. The spell negates darkvision . All characters within the sphere of magical darkness have disadvantage to attack, but advantage to attack other creatures in the darkness. This advantage and disadvantage cancel each other out . All creatures within the space of a darkness spell battle as normal. The spell is, from a mechanical sense, pointless and negated. Certainly this discounts a proper GM who looks past it and says, "no, that's stupid," but yeah, strictly BY THE BOOK it's a pretty gross oversight by the designers of the game from a mechanical standpoint. Also, I pointed this out to the Sage Advice people some time ago and they confirmed ...

Lembas - Elvish Waybread: a real-world recipe

Here's a recipe I put together for Lembas bread. Didn't know I could bake, did you? Well, I can, and I'm pretty durned good at it when I want to be. Note: Okay, this isn't exactly directly related to OD&D, but we all know that there is a relationship between OD&D and Middle Earth, and this makes for a good holiday treat, or a nice, filling and fairly healthy snack at the gaming table. Here's how it came about: we were doing a Lord of the Rings marathon at my buddy Mike's house when the RotK extended edition came out. Mike has a 42" widescreen and a really kick ass surround sound system, so we got together at 9:00 AM on Saturday and watched all twelve-plus hours of the epic trilogy back to back. It was awesome. Anyway, I wanted to contribute something so I started searching for recipes for Lembas bread. My efforts that year were futile, but flash forward to last Christmas. I got the hankering to try again, so I looked up some recipes onli...

Psionics in Dungeons & Dragons Part I: Original D&D

Image
I'd like to take a couple blog entries to explore the concept of psionics in the early editions of D&D--specifically, original D&D and AD&D first edition. Psionics, traditionally, have been a much-reviled part of the D&D opus, and those who do not include them in their game are certainly far more common than those who do include them. It's no secret that even Gary Gygax lamented and regretted their inclusion, and didn't use them himself. As with any aspect of the game, ask 100 players why they don't like psionics, and you'll get at least 50 different answers (if not more). The vast majority, however, will come down to one of two major points: They are science-fiction feeling and simply don't have a place in a fantasy game They are overcomplicated, confusing, and simply arcane and unworkable.  I can't really address point one. If you simply don't like the idea of psionics, if you feel like they're not fantasy-feeling, and y...

Psionics in Dungeons & Dragons, Part II: Advanced D&D

Image
Now that we've looked at how Psionics work in original Dungeons & Dragons, let's examine how they work in Advanced D&D. Readers may be shocked to discover that psionics in AD&D are, in many ways, much easier and more straightforward than they are in OD&D. The two systems are very similar, but there are some important and notable differences. The next blog entry in this series will compare and contrast the two systems, but for now I want to focus on how they work to keep a clean exploration and explanation of these two rules sets, both of which offer a lot of fun and something different and mysterious for D&D games that have become a bit rote in their approach. Psionics can present an interesting approach to mysticism in an AD&D game, particularly one that seeks to represent certain styles of 1970s and 80s fantasy, particularly those of writers like Mercedes Lackey, Ursula K. LeGuin, Andre Norton, and Marion Zimmer Bradley, which in modern terms system...

Tech Blog: Xiaomi Mi Box S vs NVIDIA SHIELD TV Android TV Boxes

Image
Yeah, I know, this is an old-school gaming blog, but I needed somewhere to put this, and it's a bit of a ramble, so bear with me. If anyone is cutting the cord, this may come in handy for you. Juliette and I upgraded our streaming box today to an NVIDIA Shield TV. I had originally purchased a Xiaomi MiBox S as a test case for cutting the cord. I can now compare the two for anyone interested in going for an Android TV box.  Note that I did NOT go with the $190-$200 SHIELD Pro, which is the high end gaming version of the Shield TV, and comes with double the memory and an extra USB port. I went with the NVIDIA SHIELD TV "base" model, which looks like a cylinder. Xiaomi Mi Box S NVIDIA SHIELD TV Price  The MiBox S EASILY wins in this category, going for between $64 and $66 on Amazon. The Shield TV goes for $149 on Amazon and at Best Buy, where we bought ours.  Looks Again, I have to give the edge to the MiBox, here. It's a very unassuming small, black, square box that sit...

Wasted Lands - a Completely Customizable RPG

Here we go, folks! The final blog before the Wasted Lands Kickstarter launches ! Stay tuned for more behind the curtain looks as the campaign progresses, but this one completes the big lead-up!  Previous blogs in this series: Wasted Lands: The Dreaming Age is Imminent! Will Wasted Lands be a Retroclone? What Are Divine Touchstones? Races (Species) and Cultural Backgrounds How Do Tiered Abilities Work?   Class Abilities in Wasted Lands For some time now we've been pushing "Your Game, Your Way" as a slogan for Powered by O.G.R.E.S. games , and many wonder what kind of meaning that carries. After all, everyone claims that their game is the one you've been looking for, and the concept of a universal game system has been around almost as long as RPGs themselves. Even the earliest versions of D&D had sci-fi elements and the first edition DMG discussed melding the system with a range of genres.  So what do we mean exactly when we talk about O.G.R.E.S. as a customizable s...

Review: Original Dungeons & Dragons Premium Reprint

Image
  (Stock Image) Source: http://www.wizards.com/dnd/Product.aspx?x=dnd/products/dndacc/45390000 Introduction To put a crown jewel on their “Premium Reprint,” series, Wizards of the Coast has re-released the original Dungeons & Dragons rules. Specifically, this reprint is of the sixth printing, or “OCE” (Original Collector’s Edition) version of the rules. Like many fans of the old school, I was rather excited and more than a little nervous about this product. For $150, would they screw it up? Would it be handled properly? Would it, unlike the reprints for second and third editions, truly be premium? Yesterday, I headed to my FLGS and picked up my OD&D Premium Reprint. Here are my thoughts. Presentation This set is really nice. It comes in an actual wooden box, a nice nod to the original rules which came in a printed woodgrain box. The box construction is sturdy and just overall excellent. It has a nice velvet pad on the bottom to keep from scratching...

The Elegance of Non-Unified Mechanics

Image
Like a great deal of gamers in this day and age, I have long been enamored of the idea of a so-called "unified mechanic," that is, a single die roll approach to resolve most, if not all, issues in a game. Current versions of D&D, for example, use a d20 ability check approach for everything--even combat is a Strength or Dexterity check. The only things that don't use the d20 are random probability rolls (which use straight percentile) and damage. The Unisystem is another universal mechanic system, using d10 + attribute + skill vs. a target number of 9, and the cinematic version uses this for everything; there aren't even damage rolls, as damage is a flat number. Even my own Spellcraft & Swordplay original ORCS system used 2d6 for everything, with damage rolls using xd6. The Elegance of Non-Unified Mechanics There's a certain ease and straightforward-ness to this approach that's easy to appreciate. Recently, however, I've come around to a new...
