Chimera is a tabletop roleplaying engine suited to run fantasy, modern, and sci-fi themed games. Chimera uses flexible rules that allow you to put the fiction first, but with enough crunch to add more structure to the resolution mechanics if you so wish. In essence, playing Chimera is a conversation where:
• The Game Master describes the environment.
• The players describe what their characters do.
• The GM picks the most relevant abilities and asks the players to roll.
• The player rolls a ten-sided die per rank in the relevant abilities & chooses the highest.
• The GM takes in the results & narrates the outcome of the character's actions.

The book is divided into two parts that contain chapters of various lengths.

Part 1

The following chapters are designed for both PCs and GMs.
• Learn to Play: Everything you need to know about the rules that make up the Chimera Roleplaying System is found in this chapter. Make sure you read this first.
• Characters: This chapter goes over everything related to character creation, character development, filling a character sheet, and how to build certain archetypes.
• Races & Traits: The races & Traits chapter contains information about the races you can play in fantasy, modern, and sci-fi settings.
• Perks: The perks chapter contains abilities that you can take that help you improve and expand the capabilities of your character.
• Powers: All the rules regarding powers and those who wield them are found in this chapter.
• Wealth & Equipment: This chapter goes over the abstract system of owning Resources and Wealth, as well as equipment, and the services you can acquire with them.

Part 2

It only contains three chapters, but these are crucial for any aspiring GM.
• Game Mastering: This long chapter goes over what is to be a GM, tips I have found useful throughout my years as a GM, and a toolbox for creating adventures, campaigns, and character options.
• Enemies: This chapter contains an assortment of creatures to pit against the PCs in your game.
• Example Setting: This chapter holds the notes of a small campaign setting hurriedly put together to test how well all Chimera elements worked collectively.

This chimeric beast heavily draws inspiration and mechanics from games such as Apocalypse World, games derived from the d20 system, Dungeon World, and Fate Core. You can see these influences in the core mechanics of the game.
• Dice Pool: The Chimera Roleplaying System uses ten-sided dice to determine the success or failure of actions and circumstances presented during the game. Your dice pool is the number of dice you are allowed to roll to resolve a task's outcome. Your pool is composed of your ranks in the appropriate abilities (Action + Approach).
• Abilities: Abilities are the bread and butter of all characters. They define what a character can or can't do and how well they can do it. Actions represent the overall capabilities of your character to get things done. If actions are what you can do, the approach represents how you get things done. A situation might have different approaches, and you get to choose how things get done.
• When To Roll: Whenever the outcome of a task is uncertain and has some real consequences, it is time to gather your dice and roll. As a player, you will make most of the rolls in the game.
• What To Roll: To determine the outcome of your character's action, you roll a d10 per rank in the relevant abilities to form your dice pool. You roll and keep the highest die of them all.
• Degrees of Success: How well or bad you do will depend on your result when you roll to determine a task's outcome. When you roll to determine an outcome and have at least a ten, it counts as a success. If the highest die from your roll is a nine, it counts as a partial success. If you roll and your result has no 10s or 9s, it counts as a failure.

In Chimera, you follow ten steps to build your character, allowing you to choose essential aspects of your avatar such as their background, race, extraordinary abilities called perks, their principles and goals, and their gear.
• Race: Each race has a list of inherent and optional traits and perks to choose from to tailor your character to your needs. If the options presented do not suit you, the game has optional rules to implement that allows you to choose the traits that best fit your character, regardless of race.
• Perks: They can help you boost something you are already capable of doing or let you do things impossible for others, such as casting spells. You can spend XP to learn any perk you want as long as you meet the requirements and take some downtime to do it.
• Equipment: Select from a vast selection of gear and services to build your character. Equipment can be enhanced in many ways. They can be made from different materials, possess other gadgets to increase versatility, refined craftsmanship to strengthen protection, or resist different types of damage such as ballistic and energy. Want to make a laser sword? Buy a sword and pay for the concealable and energy modifications, and you are good to go!
• Wealth: Chimera uses an abstract wealth mechanic where the minutiae of keeping track of everything owned, bought, and how much money you have left isn't important. It can be used in any game, be it a fantasy, modern, or sci-fi setting where there is a fairly standard economy. It could also be used in an apocalyptic setting where keeping track of every resource you have left and living on the edge is part of the game's focus. It all depends on the interpretation given to wealth, as explained in the sections below.
