Crafting Crits

Crafting an item has a chance to produce a higher-rarity result. The crit chance scales with skill level above recipe requirement, equipped luck, and Champion bonuses.

Crit Chance

levelDelta = skillLevel - requiredLevel

critChance = clamp(0.05 + levelDelta * 0.01 + luck * 0.002, 0.01, 0.5)

Constant	Value	Description
`BASE_CRIT_CHANCE`	5%	Crit chance when skill level matches recipe requirement
`CRIT_CHANCE_PER_LEVEL`	+1%	Additional crit chance per level above requirement
`LUCK_CRIT_BONUS_PER_POINT`	+0.2%	Additional crit chance per point of luck
`MIN_CRIT_CHANCE`	1%	Floor crit chance
`MAX_CRIT_CHANCE`	50%	Ceiling crit chance
`BONUS_MULTIPLIER`	1.1x	Champion multiplier applied before craft crit caps

Champion Bonus

Champion supporters multiply craft crit, rare craft, and epic craft chances by 1.1x before each chance is clamped to its normal cap.

championCritChance = min(baseCritChance × 1.1, 0.5)

The same multiplier is applied to rareCraftChance and epicCraftChance before the rare and epic maximums are enforced.

Rare Craft Chance

When a crit succeeds, there is a separate chance the result is rare instead of uncommon.

rareCraftChance = clamp(0.005 + levelDelta * 0.001 + luck * 0.0005, 0, 0.04)

Epic Craft Chance

An even smaller chance exists for the crit to produce an epic item.

epicCraftChance = clamp(0.0005 + levelDelta * 0.0001 + luck * 0.00005, 0, 0.004)

Crit Rarity Resolution

When the crit roll succeeds, the resulting rarity is determined by comparing the roll against the epic and rare thresholds:

If roll < epicCraftChance: Epic
Else if roll < rareCraftChance: Rare
Otherwise: Uncommon

Bonus Stat Ranges

A crit adds a random bonus stat to the item. The bonus value is a percentage of the item's base stat.

Constant	Value	Description
`MIN_BONUS_PERCENT`	10%	Minimum crit bonus as percent of base stat
`MAX_BONUS_PERCENT`	30%	Maximum crit bonus as percent of base stat
`MIN_BONUS_MAGNITUDE`	1	Minimum guaranteed bonus value
`BASE_TURN_COST`	50	Base turns per crafting action
