Kalos Mechanism 4e EN:Introduction

What Is This?

Kalos Mechanism is an open roleplaying game system. If you have an idea for a game -- the setting, the history, the conflicts, the kinds of characters, the kinds of adventures you think would be fun to play... all of the important things, in other words -- here is a game system you can plop that on top of and run with it.

If this were a full game: This is where the game author (that's you!) would describe the "elevator pitch" for their game. What it is, what makes it different, and why folks will have fun playing it.

What Is An "Open Game"?

Simply put, an "open game" is one that you may adapt and share, as long as everyone else can do the same with what you create. To that end, the text used in this document is licensed under the Creative Commons Attribution-ShareAlike 4.0 License. You are free to:

What Is A "Roleplaying Game"?

Roleplaying involves taking on a persona or character and making decisions based on what that character would do in a given situation. Maybe those decisions aren't the most tactically advantageous, but that's part of the fun of roleplaying.

Games have rule systems that govern conflicts, and which determine whether a character is successful when they attempt something. This is what you are reading now. In most games, there is some random element to make the game more fun. Kalos Mechanism uses two six-sided dice (2d6).

The Players

In a roleplaying game, each player adopts a persona called a player character, or PC. The player characters are imaginary people who inhabit the fictional universe of the game.

In many ways, the player is like an actor who chooses their own part and writes their own lines as the play progresses. The game moderator sets the stage and introduces the characters to their world, but the story is driven by the player characters.

The Game Moderator

The game moderator, or GM, creates the story and portrays everyone that the player characters encounter during their adventures. These are called non-player characters, or NPCs. Using events and NPCs, the GM provides challenges to the PCs. The players help create the adventure by responding to the challenges the GM presents and by pursuing the PCs' own goals. This dynamic creative process creates a story which neither the game moderator nor the players could have created alone.

Ground Rules

Be Cooperative

A roleplaying game is fundamentally a cooperative activity. The players are not in competition with the GM nor with each other. The goal of a role-playing game is to experience fun stories and to entertain everyone at the table.

Expert Tip: Making the game fun is everyone's responsibility.

• Encourage each other — If someone does something cool, or has a great idea, let them know. It will make them feel good, and it will let people know what kind of game you find fun.
• Embrace setbacks — Don't get frustrated if things are going badly. Recovering from a setback makes the victory sweeter.
• Be considerate — Don't hog the spotlight. Take turns being the center of attention.
• Don't play a jerk — Being "true to your character" is not an excuse for being obnoxious.
• Respect everyone's boundaries — If a topic or a certain plot element makes any of the players uncomfortable, respect that and avoid it. Consider using John Stavropoulos' X-Card, particularly if the players are new to each other.

Use Common Sense

If something in the rules violates the way you think your game should work, then override it. If the rules permit something ridiculous, or would prevent something completely ordinary, then override them.

Expert Tip: Don't use the rules unless you need to.

In fact, if you can play a fun game session without referring to the written rules, you should. Saying "it works like this" is often a better solution than flipping through a rulebook for an answer.

Avoid Rule Arguments

Sooner or later, there will be a difference of opinion among the players regarding what a rule means, or how a rule should be implemented. The time for rule discussions is between games, not during a game. If a rule discussion sidetracks the game, the game moderator should make an interim decision and table additional discussion for later.

Core Mechanics

Abilities

Each character has access to three types of abilities:

• Skills — allow a character to solve problems and accomplish tasks
• Gifts — range from exceptional human abilities to less flamboyant posthuman abilities
• Powers — are exceptional abilities that normal people do not have

See the Skills, Gifts, and Powers chapters.

Additionally, each character has the following characteristics:

• Power Level — is assigned by the GM, and represents the strength of a character's technological might, alien potency, psychic ability, or what have you
• Endurance — represents a character's ability to physically and mentally exert themselves
• Health — represents a character's ability to withstand physical and mental injury

See Characteristics in the Creation chapter.

Rolling Dice

When a character attempts a task, the player must roll dice to see if the character succeeds. The player rolls two six-sided dice (2d6) and adds them together. The player adds this to the character's appropriate skill (Ranged Combat, Socializing, etc.). This total is the character's Action Value, or AV. If the character's Action Value equals or exceeds the DV (Defense Value or Difficulty Value) assigned by the GM, the character's attempt succeeds.

Rolling dice is covered in more detail in the Actions chapter.

Bonuses And Penalties

If something significantly aids or impedes a character, the GM may apply a standard bonus (+Template:KM4 SKILL BONUS AV, +Template:KM4 SKILL BONUS DV) or a standard penalty (-Template:KM4 SKILL BONUS AV, -Template:KM4 SKILL BONUS DV). In extreme cases, the GM may apply a double bonus (+6 AV, +6 DV) or a double penalty (-6 AV, -6 DV).

Only the highest bonus applies. Penalties are cumulative.

Attack bonuses and penalties typically apply to one roll. Defense bonuses and penalties typically apply until the beginning of the character's next turn.

Damage

If the attacker's roll succeeds, the player rolls for damage based on the character's Power Level (1d6 + Power Level) or on the Equipment Level of the weapon (1d6 + Equipment Level). The target's resistance (Damage Resistance, Alteration Resistance, or Mental Resistance) is deducted from the points of damage.

If the attack is a normal attack, the remaining points of damage are deducted from the target's Health (or Endurance, if it is a stunning attack).

If the attack is a mental attack or an alteration attack, divide the remaining damage points in half (round down, even if the fraction is more than one-half, to a minimum of 1).

Roll damage and deduct resistance before dividing.

Rounding

When a number is divided, round down, even if the fraction is more than one-half, to a minimum of 1. For game purposes, half of 5 is 2, and half of 1 is 1.

Glossary
