Vaal Orb outcomes

4 outcomes / 9 enchantments

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

No change.

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.

Adds a special Vaal enchantment to the item.

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.

How it works

1 interactions

Pierce-to-return scaling

After piercing the required two to four times, attack projectiles return and gain increased hit damage and critical chance for each pierce.

Important details

Projectiles return only after meeting the rolled pierce-count threshold.

MechanicReturning Projectiles

Returning Projectiles travel back to the entity that originated them after reaching the end of their travel or hitting their final target.

MechanicDeflect

Deflection Rating gives a chance to Deflect damage from Hits. A normal Deflection prevents 40% of the Hit damage, while the chance depends on your Deflection Rating and the attacker's Accuracy Rating.
