Item Stat Scaling¶

The inventory stat UI derives live item stats from encoded Warcraft item fields. The object tooltip can be stale; these formulas match the stat triggers.

Encoded Fields¶

Field	Runtime Field	Meaning
`iuse`	`ITEM_IF_NUMBER_OF_CHARGES`	Three digits: guaranteed amount rank, quality rank, upgrade rank
`iclr`	`ITEM_IF_TINTING_COLOR_RED`	Guaranteed stat type
`ipri`	`ITEM_IF_PRIORITY`	Main stat slot 1, encoded as stat code + unused digit + multiplier rank
`ilev`	`ITEM_IF_LEVEL`	Main stat slot 2, encoded as stat code + unused digit + multiplier rank
`icid`	`ITEM_IF_COOLDOWN_GROUP`	Sub stat slot, encoded as stat code + unused digit + multiplier rank
item user data	`GetItemUserData`	Dynamic sub stat slot assigned by some drop systems
`iclg`	`ITEM_IF_TINTING_COLOR_GREEN`	Weapon damage seed or armor/health seed depending on item prefix

Quality Multipliers¶

1	Common	1.15	1.15	1.3
2	Uncommon	1.3	1.3	1.45
3	Advanced	1.6	1.6	1.75

3	Focus
4	Adaptability
5	Mastery

Guaranteed Amounts By Quality¶

Amounts below use upgrade rank 1, matching many generated gear defaults. The formula is basestat[amount_rank] * (quality_multiplier[quality_rank] + quality_multiplier[upgrade_rank] - 1).
