For a few years now, I've been developing Tiny d10 - a free, rules-light alternative to complex tabletop RPGs like Dungeons & Dragons or Pathfinder. Like these games, Tiny d10 is a traditional tabletop RPG, wherein a game master guides two-to-six players through epic adventures across fantastical landscapes of imagination. Unlike these games, however, Tiny d10 is small: the core rules can be read in 20 minutes, and a character generated in 10. Further advantages include quick action resolution with just a single 10-sided die, a variety of classes and races, and a growing library of game content!

I think it will fit in nicely here on Steemit. So without further delay, I present to you the full, unabridged, and forever free Tiny d10: Core Rules.

Please find the printable rules here.

To play Tiny d10, you'll need:

• One game master (GM)
• Two-to-six players
•  One 10-sided die (1d10)
• Several pencils
• A character sheet for each player.

The steps below will guide you through character creation and rules of play.

Creating a Character

Each player will create a character whom they will use to interact with the fantasy worlds of Tiny d10. These characters will embark upon adventures and quests, gaining allies and slaying enemies in search of fame, fortune, or perhaps something more.

During character creation, consider things like your character’s appearance, background, and unique life experiences.

Step 1: Choose your race.

Race determines a character’s general appearance, as well as special racial abilities.

Dragonlings are ancient, draconic humanoids. They are fiercely loyal and believe the world to be black-and-white, making them great allies and fearsome enemies. They are tall, broad-shouldered, and clad in thick scales that come in a variety of colors. Dragonlings can live for more than 350 years.

Dragonlings gain the following racial bonuses:

+1 to intimidate; -1 to magical attacks against the dragonling; +1 to power at levels 1, 3, and 5; one breath weapon:

Halfings are mysterious humanoids. They are intensely private and reclusive, though when among companions are warm and personable. They are short, slender-framed, and have youthful faces - regardless of their age. Halflings can live for more than 130 years.

Halflings gain the following racial bonuses:

See up to 100’ in low-light; +1 to sneak; -1 to ranged attacks against the halfling; +1 power point per level.

Humans are typically the most prevalent race. They are hardy and dutiful, true to their cultures and their peoples. They are average to tall height, athletic to muscular build, and their appearance varies culturally. Humans can live for more than 90 years.

• Stunning spell - any attack spell will also have the stun effect (target loses 1 turn). Cost: 1 power point.

Step 3: Assign your character’s attribute scores.

Attributes determine a character’s physical strength, charisma and wisdom, awareness and intelligence, and agility. Attribute scores are added as bonuses to rolls. 5 is the highest, indicating complete mastery, while 0 is the lowest, indicating average proficiency.

Characters begin with the following scores: 2, 1, 1, and 0. Assign each score to the attribute of your choosing.

Aspect is a measure of consciousness and natural charisma. Added as a bonus during things like persuading or convincing someone, detecting dishonesty, or intimidating someone. Additionally, the aspect score is added as a bonus when casting natural spells.

Intellect is a measure of mental acuity and sharpness. Added as a bonus during things like disarming a trap, determining if you have learned or know something, or trying to decode an ancient language. Additionally, the intellect score is added as a bonus when casting magical spells.

Power is a measure of physical strength. Added as a bonus during things like breaking down a dungeon door, swimming against a river, or wrestling an unruly beast to the ground. Additionally, the power score is added as a bonus when making melee attacks.

Reflex is a measure of speed, dexterity, and reaction. Added as a bonus during things like dodging a rolling boulder, jumping across a chasm, or navigate rough terrain. Additionally, the reflex score is added as a bonus when making ranged attacks, or melee attacks with lightweight weapons.

Step 4: Assign hit points and power points.

Divide 10 points between hit points and power points.

Hit points (HP) represent the amount of damage a character can take before dying. When hit points are reduced to 0, a character is unconscious and dying.

Power points (PP) are added to challenge and check rolls to improve the likelihood of success; may only spend one point per roll (unless otherwise noted).

Step 5: Generate magic points.

When creating a spell-casting character, roll 1d10 to determine your starting magic points.

On a roll of:

• 1-5 | 4 magic points
• 6-9 | 5 magic points
• 10 | 6 magic points

Magic points (MP) represent the total amount of magical power available to magic-users; it is spent when casting spells.

Playing the Game

With your completed character in hand, it’s time to play the game. Much of this will be in the form of roleplaying, and will rely on a player’s acting, wit, and quick thinking. Such interactions will often not require die rolls. However, there will be times when rolls are unavoidable. Any attempt to do something that requires skill to succeed, or that could result in failure - like breaking down a dungeon door or navigating a twisting forest labyrinth - requires a check.

Checks

When attempting to do something that could result in failure (fording a raging river, staying astride a frightened horse, or hearing the soft footsteps of approaching enemies), a check should be made. To make a check, roll 1d10 and add the relevant bonuses.

There are two types of checks:

Action checks consist of attempts to perform an action like climb a tower, dodge a falling rock, or hide in a nearby bush. These include attack rolls, toughness checks, saves, and more.

The following is an example of an action check:

Your character Alanthea, the level 1 rogue, approaches the towering cliffside. The goblin’s trail has led her this far, and she is determined to end the hunt.

The rock face before her, while some 75 feet tall, has generous handholds and a rough surface that’s easy to grasp, making the climb a simple toughness of 4 (toughness 4 power/reflex check).Using 1d10, you roll a 4, and add Alanthea’s reflex bonus (since her reflex attribute is highest of the two) of 2 for a total of 6. Alanthea easily scales the wall, and at its peak finds the fresh trail of her quarry.

Perception checks consist of attempts to perceive something, like seeing hidden or obscured objects, or hearing hushed voices or furtive movements. Perception checks are performed by rolling 1d10 and adding the intellect attribute bonus. Skill bonuses from spot or listen may also be added.

The following is an example of a standard perception check:

After several leagues through the thick forest, Alanthea loses the goblin’s trail. She stops to more closely examine the forest floor. To do so, make a perception check.

Using 1d10, you roll a 7, and add Alanthea’s intellect bonus of 1 for a total of 8. Alanthea quickly spots the goblin’s hasty attempt to cover its tracks - a simple feat with a toughness of 5 (toughness 5 perception check). She is again on the hunt.

A check’s toughness represents all the factors that make it difficult. In combat, these are things like an opponent’s skill, dexterity, and defenses; in action, these are things like terrain, environmental conditions, and other variables.

Check Toughness

To determine a check’s toughness, consider the following:

T4-T6 | simple toughness - easy checks; climbing a wall with large handholds, or attacking weak opponents like goblins.

T7-T8 | moderate toughness - challenging checks; swimming against a strong current, or attacking well-trained opponents like castle guards.

T9-T10 | difficult toughness - hard checks; sneaking into a well-guarded court, or attacking large opponents like giants.

T11-T12 | extreme toughness - even harder checks; controlling a ship during a gale, or attacking powerful opponents like dragons.

T13-15 | impossible toughness - unimaginably hard checks; mounting and flying a wild dragon, or fighting a demi-god.

Saves

When there is risk of immediate death, dismemberment, or similarly dire consequences, a save should be made. A standard save is performed by rolling 1d10 and adding relevant attribute bonuses and/or skill bonuses to the result. Succeeding a save immediately cancels any deadly effects, but may still cause serious injury. A standard save has a toughness of 5, but certain conditions (like spells, effects, or environmental factors) can change that.

Challenges

When two characters attempt the same thing at the same time, a challenge should be performed. A challenge is performed by each character rolling 1d10 and adding relevant attribute bonuses and/or skill bonuses to the result. The results are then compared, and the highest of the two succeeds the challenge.

Combat

Combat begins according to reflex scores: highest first, lowest last. Ties should be settled with 1d10.

The following is an example of a standard combat turn:

Alanthea draws her dagger and stands, at last, face to face with her opponent: a snarling goblin with a scar drawn from his forehead to his chin.

She makes an attack roll using 1d10 and, since she's using a dagger, adds her reflex score. She rolls a 6, and adds her bonus of 2, for a total of 8. The goblin has a toughness of 5 (T5) and 1 HP, and Alanthea viciously slashes his throat, dealing 1 damage. He dies instantly.

Movement in Combat

All classes are moderate in speed and may move only up to their maximum speed range per turn. Environmental factors (like storms or difficult terrain) may affect that maximum speed.

Slow: 10-20 ft | Moderate: 20-30 ft | Fast: 30+ ft

Simplified Combat Rules

• One round consists of all combatants' turns, and represents roughly 5 seconds.
• Only 1 attack/spell per turn (unless otherwise noted).
• Only one move sequence per turn (unless otherwise noted).
• Less significant actions, like talking, may be done freely.
• Damage is typically 1, though may be more.
• Ranged and small weapon attacks use reflex; magical spells use intellect; natural spells use aspect; melee attacks use power.

Combat Advantage

Under certain circumstances, a character may receive a +1 attack bonus if they are in an advantageous position. However, if the attack does not succeed, a negative condition may be imposed.

Healing

Standard healing restores 1 hit point (as well as power and magic points) per successful T6 intellect check (unless the character possesses the heal skill, which succeeds automatically). During combat, an attack action must be forfeit to heal. Out of combat, characters may make 2 heal checks per in-game hour. If characters do not or cannot heal, they automatically heal at a rate of 1 hit points per 2 in-game hours.

Additionally, a quick rest of 2-3 in-game hours will restore 3 hit points, magic points, and power points.

Dying

At 0 hit points, characters are considered immobilized and dying. After 4 turns at 0 hit points, they will expire.

Leveling Up

Characters begin as level 1 folks, and advance by earning experience points (XP). Experience points are earned by slaying/defeating opponents (usually giving between 1-5 XP), but also by succeeding checks in spectacular and heroic ways (usually giving 1 XP). Experience points are lost upon advancement and must be gained anew.

As characters gain levels, their powers and strengths improve. The levels are:

Level 2: Explorer (25 XP)

• +1 skill, +1 class ability, +2 spells (if applicable), +1 to any attribute, +1 weapon proficiency.
• +2 power points or +3  magic points.

Level 3: Adventurer (75 XP)

• +1 class ability, +2 spells (if applicable), +1 to any attribute.
• +2 hit points or +1 toughness.
• +2 power points or +3  magic points.

Level 4: Hero (150 XP)

• +1 skill, +1 spell (if applicable), +1 class ability.
• Hero’s Resolve (ability): roll again if the result is 1.

Level 5: Legend (250 XP)

• +1 skill, +2 bonus to any attribute(s).
• Hero’s Presence (ability): force opponents to make an aspect challenge when attempting to attack you; if they fail, they suffer -1 to their attack.

Skills

Skills are specific competencies and can only be used in specific scenarios. For example: the spot skill can be used in a perception check to see something; the persuade skill can be used in an aspect check to convince someone of something.

When used, skills add a +1 bonus to checks. Skills can be used in combat, but not for combat. The following is a list of skills:

Added as a bonus to aspect checks:

• Detect (must be specific: detect magic, detect motive, etc)
• Heal
• Intimidate
• Persuade

Added as a bonus to intellect checks:

• Craft
• Know (must be specific: know history, know theology, etc)
• Spot
• Listen

Added as a bonus to reflex checks: 

• Acrobatics
• Conceal (must be specific: conceal item, conceal motive, etc)
• Hide
• Sneak

Wealth

The value of currency is simple and equivalent to the U.S. dollar (though easily converted to any currency form):

1 gold piece (gp) = $10 USD | 1 silver piece (sp) = $5 USD | 1 copper piece (cp) = $1 USD

Casting Toughness

Some spells, or certain conditions, may impose a casting toughness on the spell-caster, which works as a standard toughness check.

Spell Saves

Some spells allow the target to make a save before having an effect. Each spell-caster has a spell save, which is equal to their character level + casting attribute bonus (aspect or intellect) + 3.
