## ⚡ What is Surgery Extract?
Have you ever caught a Pal with an incredible god-roll passive skill like **Legend**, **Swift**, **Musclehead**, or **Runner**, but on the wrong Pal? Or do you have an unwanted negative trait like **Coward** or **Slacker** ruining an otherwise perfect Pal?
**Surgery Extract** is the ultimate genetic engineering utility mod for Palworld! It integrates seamlessly with the **Operating Table**, allowing you to surgically extract any passive skill from a Pal and convert it into a consumable **Passive Implant Item** deposited directly into your bag.
You can then take that implant and inject it into ANY other Pal through the Operating Table menu!

## ✨ Key Features
* 🧬 **Universal Passive Extraction:** Extract and store over **1,920+ passive skills** — including all vanilla traits, Alpha traits, raid boss passives, and custom modded passives (Traitstorm, Passives Expanded, etc.).
* 💉 **Direct Operating Table Integration:** Simply click any passive slot on the Operating Table UI and press the hotkey. No complex console commands needed.
* 🛡️ **100% Crash-Proof Native Engine Removal:** Built using Palworld's native `UPalIndividualCharacterParameter:RemovePassiveSkill` C++ engine API. It cleanly recalculates all Pal stat buffs and updates the game state without memory corruption or UI errors.
* 🎒 **Instant Inventory Delivery:** Extracted passives are instantly packaged into `PalPassiveSkillChange_Consumable` implant items in your inventory.
* 🗑️ **Force Remove (Negative Trait Eraser):** Want to simply delete a negative trait like Slacker or Brittle without keeping an item? Use the Force Remove hotkey!
* 🌐 **Palworld v1.0.5+ & Multiplayer Compatible:** Fully optimized for the latest Palworld updates and UE4SS architectures.

## 🎮 Controls & Hotkeys
While interacting with the **Operating Table** and selecting a passive slot:
| Hotkey | Action | Description |
| :--- | :--- | :--- |
| **`Shift + Alt + P`** *(or `L`)* | **Extract to Bag** | Extracts the passive from the Pal, removes it cleanly, and delivers the **Implant Item** into your inventory. |
| **`Shift + Ctrl + P`** *(or `L`)* | **Force Remove** | Erases the passive from the Pal cleanly without generating an item (perfect for clearing negative traits). |
| **`Ctrl + Alt + P`** | **Backup Remove** | Secondary safety hotkey for quick force-clearing. |
