I
The Common Ledger

Experience

Experience is the character's general growth currency. It is earned from completed dangers and useful work. When the stored total crosses the current threshold, the character advances a level and receives a pending level-up choice.

KIL
Combat

Defeating Enemies

Killing an enemy grants the enemy card's experience value. Enchanted enemies can yield larger rewards because their experience value is increased when the encounter is made more dangerous.

CRF
Craft

Crafting Recipes

Successful crafting grants the recipe's experience value. Tinkerer-style bonuses can add extra XP on top of the recipe reward.

ACT
World Actions

Harvesting and Work

Some card and location actions grant the source card's experience reward when completed. Mining, harvesting, and other practical work can therefore advance the character as well as the relevant proficiency.

II
The Rising Cost

Level Thresholds

Every character begins with a required experience value of 100. When that threshold is crossed, the threshold is paid from the current XP pool, then the next requirement doubles. Extra experience carries forward rather than being discarded.

Starting Point

The first level threshold is 100 XP. A new character stores earned XP until the total meets or exceeds that number.

Doubling Curve

After each level gained, the next required amount is doubled. The early curve is 100, 200, 400, 800, and so on.

Overflow

Leveling subtracts the current requirement from the stored XP. Any remainder stays available for future thresholds or perk spending.

Human Bonus

Human characters receive 10 percent more XP from every award before it is added to their stored experience.

III
The Branching Class

Leveling Up

Crossing the XP threshold does not immediately choose a build path. It marks the player as ready to level up. The character sheet then exposes a level-up button, and the player selects from class options that match the character's current class and level.

Class Options

When matching class records exist, the player is offered up to three choices. Each option can rename the character class, grant +1 to a listed attribute, increase maximum health or mana, improve melee, ranged, dodge, or carrying weight, grant a specific skill, and sometimes grant random spells.

Fallback Growth

If no authored class option exists for the current class and level, the game applies a generic level-up instead. Maximum health, maximum mana, ranged, melee, and carrying capacity each rise by roughly 10 percent, and the pending level-up flag is cleared.

Separate Tracks

Level and class are separate from proficiency. Leveling changes the character's broader body of stats and class identity. Proficiency changes how well the character performs a specific practiced action.

IV
Use Becomes Skill

Proficiencies

Proficiencies are trained by doing the thing they describe. They have their own progress value, level, and threshold. A missing proficiency is created the first time it is advanced, unless the action has no valid proficiency type.

100
First Rank

Initial Threshold

A new proficiency begins at level 0 with 0 progress and a threshold of 100 practice points.

x2
Next Rank

Doubling Practice

When progress reaches the current threshold, the proficiency gains one level, progress resets to 0, and the next threshold doubles.

USE
Practice

Action Driven

Weapon attacks, spell use, trap work, location actions, stealing, crafting, runework, and similar actions advance the matching proficiency when they are performed.

V
What Practice Changes

Skill in Play

A proficiency level is not just a number in the character sheet. Different systems read it in different ways, depending on what kind of action is being resolved.

Weapons

Equipped melee and ranged weapons add the matching proficiency level to the relevant attack value. Practiced weapon use also advances the weapon's proficiency type when attacks are made.

Spells

Successful spell use advances the spell's school. The school level can add to spell duration, dodge, melee, ranged, elemental damage, and elemental defence values when the spell carries those fields.

Actions

Location and advanced actions add the relevant proficiency level to their success chance when the player already has that proficiency, then advance that proficiency through use.

Craft

Craftsmanship advances through successful craft work. Its level can improve crafted item quality and helps reduce the chance of damaging items during repair or similar inventory work.

Locks and Traps

Lockpicking can apply a larger bonus based on proficiency level, while trap interactions advance the traps proficiency when a character searches, disarms, or suffers through the mechanism.

Stealing

Stealing advances in uneven bursts rather than a fixed single point, reflecting the higher-risk, higher-variance nature of theft.

VI
Spending Growth

Perks and XP

Experience is also the resource used by the perk tree. That creates a deliberate tension: XP can push the character toward the next level threshold, but it can also be spent immediately on targeted capabilities.

Buying Perks

When a perk is unlocked, its cost is paid directly from the character's current stored experience. Each existing perk increases the cost pressure on future purchases, so a broad perk build becomes more expensive over time.

Strategic Pressure

A character close to a level threshold may delay buying a perk to secure a class branch first. A character blocked by events, recipes, or survival problems may spend XP early because a specific perk is worth more than waiting for the next level.
