Extraction Guide

How Extraction Works

Extraction lets you remove attached effects from a piece of gear. This includes decorations, engravings, and inscriptions that have been applied to the item. After extraction, the item returns to its base state — all bonus stats from cube-applied effects are gone.

CRITICAL — Materials are NOT returned! Extraction removes the effect from the item, but it does NOT give you back the materials used to create that effect. The decoration material, engraving material, or inscription material is permanently lost. You are paying 1,000g simply to free up a slot.

Think of extraction as a "reset" button for a specific slot on your gear. It clears the slot so you can apply something new, but everything that was in that slot is gone forever.

The Material Loss Tradeoff

Understanding this tradeoff is essential to using extraction correctly:

What You Pay	What You Get
1,000 Gold	One freed effect slot
The original material (lost)	The ability to apply a new material
The original effect (removed)	Potential for a better effect

In essence, you're trading an existing effect + 1,000g for the opportunity to apply a better effect. Only do this when the new material you plan to apply is significantly better than what's currently on the item.

When Extraction Is Worth It

Good Reasons to Extract

Freeing a slot on valuable gear. You have an Immortal sword with a weak inscription (+2% HP) and just obtained a rare engraving material (+15% ATK). Extract the weak inscription to make room for the powerful engraving.
Fixing a bad RNG result. Decoration and inscription give random stats. If you rolled a useless stat on a piece of gear you intend to keep forever, extraction lets you try again.
Clearing obsolete effects. An effect that was good at level 50 may be underwhelming at level 200. Extract it and apply a higher-tier material.

Bad Reasons to Extract

"I changed my mind about the color." Extraction doesn't recover materials. If you regret a decoration but don't have a strictly better replacement, leave it alone.
Extracting from gear you'll replace soon. If you're going to swap to a new weapon in a few days, don't spend 1,000g extracting the old one. Just apply materials directly to the new item.

Pro tip — Extraction + Decoration cycle: If you're chasing a specific bonus stat through decoration RNG, budget for multiple extraction cycles. Decorate → check result → if bad, extract → decorate again. Each cycle costs 300g (decoration) + 1,000g (extraction) + a new decoration material. This gets expensive fast — only do it for endgame BiS (Best-in-Slot) gear.

Extraction vs Other Options

Alternative	Cost	When Better
Extraction + re-apply	1,000g + new material	When the gear itself is irreplaceable
Apply to a different slot	Material only	When you have an empty slot on another item
Synthesize the item up	9 items + RNG	When the base item isn't special — synthesis resets all effects anyway
Sell and buy a replacement	Steam Market price	When market prices are favorable

Common Mistakes

Don't extract unless you have a replacement material ready. Extracting to create an empty slot with nothing to put in it wastes 1,000g. Have the new material in your inventory before you extract.

Don't extract from gear you might sell. Steam Market sales wipe all cube-applied effects anyway. If you extract and then sell, you've wasted 1,000g for nothing. Just sell it as-is.
