Vaal Cultivation Orb

Other Unique rule

Perfidy is not listed among the 48 corrupted Vaal Uniques with an item-specific Cultivation modifier pool. Using a Vaal Cultivation Orb follows the separate rule for other Uniques: it replaces the item with a random Corrupted Unique of the same Item Class.

Target class: Body Armours
Result: Random Corrupted Unique of the same Item Class
Exact pool: Not published as an exhaustive list

The exact random pool depends on item class and current eligibility rules, so it is not represented as a fixed item-to-item outcome.

Vaal Orb outcomes

4 outcomes / 11 enchantments

Vaal Orb can corrupt Perfidy. One applicable outcome is selected, and the item normally cannot be modified again by ordinary crafting.

01

No change.

02

Applies a modifier magnitude multiplier of 0.78x to 1.22x (in 0.01 increments) before rounding to explicit modifiers. Applies before quality effects.

The resulting values are rounded to the nearest whole number, rather than always being rounded down like most decimal values in the game. However, testing suggests the game may use truncation with a +0.5 shift instead of standard rounding. This appears to bias internally negative stats (like 10% Reduced Dexterity) toward zero, preventing some expected values from appearing while making others more common. A formula of trunc(value + 0.5) may explain this behavior.

03

Adds a special Vaal enchantment to the item.

04

Adds an item socket to weapons (including sceptres) and armour, ignoring socket limits.

For jewellery, no change. (This outcome is not removed by Omen of Corruption.)
The item cannot have more sockets than the amount of space the item takes up.
If the item is socketed with Cadigan's Epiphany, the item cannot gain an augment socket via corruption.
