Creating a Character
Through your character you interact with RPG worlds of limitless fantasy. During character creation, consider things like your character’s appearance, background, and unique life experiences.

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.
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 climbing a cliff face. 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.
When first creating a character, 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 one per roll (unless otherwise noted). Replenished at the same rate as hit points.
Step 5: Generate magic points.
When first creating a 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.
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:
Standard checks consist of attempts to perform an action like climb a tower, dodge a falling rock, or hide in a nearby bush.
The following is an example of a standard 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 see or hear 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, you 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 6 (toughness 6 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.
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 – harder checks; swimming against a strong current, or attacking well-trained opponents like castle guards.
T9-T10 | difficult toughness – challenging checks; sneaking into a well-guarded court, or attacking large opponents like giants.
T11-T12 | extreme toughness – tougher checks; controlling a ship during a gale, or attacking powerful opponents like dragons.
T13-14 | impossible toughness – unimaginably hard checks; mounting and flying a wild dragon, or fighting a demi-god.
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.
When two players 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 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 hit points, 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 represents roughly 5 seconds.
- Only 1 attack per turn.
- Only one move sequence per turn.
- 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.
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.
Standard healing restores 1 hit 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 4 heal checks per in-game hour. If characters do not or cannot heal, they automatically heal at a rate of 1 hit points per 4 in-game hours.
At 0 hit points, characters are considered immobilized and dying. After 4 turns at 0 hit points, they will expire.
Characters begin as level 1 folks, and advance by earning experience points (XP). XP is 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). XP is 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 bonus to an attribute, +1 weapon proficiency.
- +2 power points or +3 magic points.
Level 3: Adventurer (75 XP)
- +1 class ability, +2 spells (if applicable), +1 bonus to an attribute.
- +2 hit points or +1 toughness – and – +2 power points or +3 magic points.
Level 4: Hero (150 XP)
- +1 skill, +1 spell (if applicable), +1 class ability, +1 to anything.
- Hero’s Resolve (ability): roll again if the result is 1.
Level 5: Legend (250 XP)
- +1 skill, +2 bonus to attributes.
- Hero’s Presence (ability): force opponents to make an aspect challenge when attempting to attack you; if they fail, they lose their turn for one round.
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.
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)
Added as a bonus to intellect checks:
- Know (must be specific: know history, know theology, etc)
Added as a bonus to reflex checks:
- Conceal (can be broad: conceal item, conceal motive, etc)

Magic is conjured using magic points. Typically, only characters that possess the spell-casting ability can use magic. Magic points are regenerated just like hit points.
Unless otherwise specified, spells are a guaranteed success, though some spells may require an attack or check roll, usually versus toughness.
Some spells, or certain conditions, may impose a casting toughness, which works as a standard toughness check.
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 and casting attribute bonus (aspect or intellect) + 3.
