How corruption works
How often the Corruption Orb drops is on Currency orbs.
Put the Corruption Orb and one weapon, armor or quiver alone in the Horadric Cube and press Transmute. It works on every base, and a corrupted item can't be corrupted again. The item gets one random property from its slot's list below and is marked Corrupted. In 24-26% of uses (by slot, see below) it bricks instead: the item is rerolled as a corrupted rare of the same base and item level. Runewords too: a bricked runeword is a rare of its base, and the runes in it are gone.
Every corruption gets its result: before, 1 in 50 stayed Corrupted with nothing added, and the chances above were one roll off.
The item's own line for the mod the orb added turns red, so you see at once what the corruption gave, and its value shows only once (the line shows the item's total for that mod, which can include its own affixes).
If the game's lines can't be read (after a game update, say), a red line just above Corrupted names the mod instead (for example Enhanced Damage), without its value, which stays in the mod's normal line.
Affixes by item slot
Each slot has its own list. Class helms (Barbarian helms, Druid pelts) and circlets use the Helms list; Paladin shields and Necromancer heads use the Shields list; every weapon, Amazon, Assassin and Sorceress weapons too, uses the Weapons list. Runewords, uniques, set items and rares use their base's list. Values are rolled inside the range shown.
