QualityProfile

The seven-tier quality ladder for ONE class of item (tables/quality_profiles.ron) — OURS, not the SRD's, which prices a longsword but never says what a FINE one is. tiers carries all seven in ladder order (Trash → Legendary), so every item of the class reads its modifiers from the same row and no tier can be quietly omitted.

Field	Type	Required	Description
class	string	required	The item class this profile covers ("weapon"/"armor"/"tool"/"lock"/"good").
tiers	TierEffects[]	required	All seven tier effects, in ladder order.

Nested shapes

Every shape QualityProfile closes over, so this page stands alone.

TierEffects

One rung of the seven-tier quality ladder: what an item of this tier is worth and how it performs, as deltas off the Normal baseline. A class-wide row in a QualityProfile, or a single item's override of one.

Field	Type	Required	Description
ac_delta	integer	optional	AC delta at this tier (armor); absent = n/a.
attack_delta	integer	optional	Attack-roll delta at this tier (weapons); absent = n/a.
damage_delta	integer	optional	Damage delta at this tier (weapons); absent = n/a.
dc_delta	integer	optional	Lock DC delta vs the Normal DC 10 base at this tier (locks); absent = n/a.
integrity_factor	number	optional	Max-integrity multiplier (the `structure` class) — defaulted so the arms/tool/lock profiles never spell it.
tier	QualityTier	required	The quality tier this row describes.
value_factor	double	required	Worth multiplier at this tier (every class).
work_factor	number	optional	Work-output multiplier at this tier (tools); absent = n/a.
