What it does

"Modifies an item unpredictably and Corrupts it." Corrupted items can't be modified again by normal currency, so a Vaal Orb is always the last step of a craft. A Hinekora's Lock lets you see the result before you commit.

What can happen

On gear, the outcomes include no change, rerolled modifiers, a Vaal enchantment or an extra socket. On waystones it can move the tier up or down, which is the main way players reach Tier 16 waystones.

New in 0.5

Patch 0.5.0 changed the corruption that pushes values past their normal range: it now multiplies each modifier's current value instead of rerolling it.
