Vaal Orbs: How Corruption Works and When to Gamble

The Vaal Orb is Path of Exile's high-stakes gamble. Used on an item, it applies one of several random outcomes — some amazing, some ruinous — and the item becomes corrupted, meaning you can no longer modify it with normal currency. Knowing when to Vaal is the whole skill.

What corruption can do

Applying a Vaal Orb to a rare/magic item rolls one of roughly these outcomes:

1. Nothing changes — the item is now corrupted but otherwise identical.
2. Add or change an implicit — sometimes a powerful corrupted implicit (this is often the goal).
3. Reroll the item as rare with new mods — usually a downgrade (a "brick").
4. Turn it into a rare with white sockets / other socket outcomes (on some item types).

Because corruption locks the item, the risk is real: if you Vaal a finished item hoping for a better implicit and hit the reroll, it's gone.

The odds, roughly

The four outcomes are broadly equal-ish, so treat a Vaal on a finished item as a ~1-in-4 to brick it gamble. That's why the standard advice is:

• Vaal cheap, replaceable items freely (gem corruptions, cheap bases, jewels).
• Only Vaal an expensive finished item if the upside (a specific corrupted implicit) is worth a real chance of losing it — or use a double-corrupt / temple method where appropriate.

Where crafting fits

Corruption is the last step, after crafting. The workflow is:

1. Craft the item to completion with normal currency (see the beginner currency guide or influenced crafting).
2. Decide if the corrupted-implicit upside justifies the brick risk.
3. Vaal — and accept the result, because there's no undo.

Since corrupted items can't be rolled further, automation applies to the crafting before the Vaal, not the Vaal itself. Exiled Bench gets your item to a finished, keepable state efficiently; the gamble at the end is yours to take.

Tips

• Buy a spare. For a build-defining corrupted implicit, it's often cheaper to buy a pre-corrupted item than to gamble your own.
• Gems love the Vaal. Corrupting gems for +1 level / quality or a Vaal version is far lower-stakes than corrupting gear.
• Never Vaal on impulse. If you'd be gutted to lose the item, don't.

Corruption is the one step crafting can't take back — so finish the craft cleanly first, then decide if the gamble's worth it.
