# Skull Coin Farming
***
## Overview
**Skull Coins** are a premium quest currency used across XileRO for top-tier trades — [Enhanced Monkey Fist Card](/content/pve-content/enhanced-monkey-fist-card.md), Dark Devil & Infinity sets, [Shadow Sovereign's Legacy](/content/pve-content/shadow-sovereigns-legacy.md), Casino costume tickets, and seasonal event rewards.
The **only** reliable way to farm Skull Coins in the open world is by hunting the **Mutated Monster** — a dragon-class MVP that escapes from the Yuno lab and terrorizes Yuno's outer fields roughly once per hour, every hour of the day.
{% hint style="info" %}
Each spawn wave places **3 Mutated Monsters** — one on each of `yuno_fild01`, `yuno_fild02`, and `yuno_fild03`. All three can be killed per wave.
{% endhint %}
## Event Monster
| Monster | Location | Description |
| :----------------------------------------------------------------------------------: | ---------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- |
| Mutated Monster
(Ebon Howler — Mob ID 20088)
| Yuno Fields 01 / 02 / 03
@warp yuno\_fild01
@warp yuno\_fild02
@warp yuno\_fild03
| Level 160 Dragon-race MVP boss. 10.87M HP, Neutral Lv4, Large size. Escapes the Yuno lab every hour and drops **Skull Coin**. |
{% hint style="warning" %}
Spawns are **boss-flagged** — Dead Branch and similar summons cannot replicate them. You must hunt them during the event spawn windows.
{% endhint %}

## How It Works
{% stepper %}
{% step %}
#### Step 1: Wait for the Spawn Announcement
An NPC named **HE\_HiddenDragonNPC** broadcasts on the `#events` channel when the event triggers:
> *"Some evil monster has broken loose from the lab in Yuno and is terrorizing yuno\_fild01, yuno\_fild02 and yuno\_fild03! The citizens of Yuno urgently need your help!"*
Followed 15 seconds later by:
> *"Oh no! A mutated monster has broken loose!"*
At that point, 3 **Mutated Monsters** spawn — one per Yuno field.
{% endstep %}
{% step %}
#### Step 2: Warp to a Yuno Field
Use the player commands to travel instantly:
| Command | Target |
| ------------------- | ------------- |
| `@warp yuno_fild01` | Yuno Field 01 |
| `@warp yuno_fild02` | Yuno Field 02 |
| `@warp yuno_fild03` | Yuno Field 03 |
{% hint style="info" %}
The monster spawns randomly inside a **350×350 area** on each field. Use `@whereis 20088` or `@mobsearch Mutated Monster` to locate it faster.
{% endhint %}
{% endstep %}
{% step %}
#### Step 3: Kill the Mutated Monster
Burst it down before another player beats you to the kill — MVP loot goes to whoever lands the most damage.
| Reward Item | Drop Rate |
| ----------------------------------------------------------------------------- | ---------------------------------- |
|  Skull Coin (31288) | \~3% (Etc-scaled, steal-protected) |
| Old Violet Box (617) | \~0.34% |
|  Old Card Album (616) | \~0.34% |
|  MVP Soul (20114) | \~0.14% |
|  Blood Thirst (6470) | \~3.49% |
|  Aevir Oil (6559) | \~1.79% |
|  Ethereal Dyestuff (6228) | \~1.34% |
|  Uber Lootbox 2025 | \~0.04% |
{% hint style="success" %}
When you land the killing blow, the server broadcasts your name on the `#events` channel as the hero who saved Yuno!
{% endhint %}
{% endstep %}
{% step %}
#### Step 4: Repeat Every Hour
The event re-triggers **23 times per day** at the following server times:
| | Spawn Times (server time) | |
| :---: | :-----------------------: | :---: |
| 00:00 | 01:01 | 02:10 |
| 03:15 | 04:25 | 05:01 |
| 06:05 | 07:10 | 08:23 |
| 09:15 | 10:24 | 11:11 |
| 12:12 | 13:13 | 14:14 |
| 15:12 | 16:13 | 17:15 |
| 18:16 | 19:18 | 20:15 |
| 21:18 | 22:20 | — |
{% hint style="warning" %}
When a new wave triggers, **all existing Mutated Monsters on Yuno are wiped** before the fresh 3 spawn. Don't wait on a previous wave's remnant — finish it off or cut your losses.
{% endhint %}
{% endstep %}
{% endstepper %}

## 💡 Tips
* **Park an alt on each field** — since 3 monsters spawn simultaneously, having characters pre-warped across `yuno_fild01/02/03` lets you claim more kills per wave.
* **Hit hard and fast** — MVP drops go to the player who does the most damage, not the killing blow. Bring a burst class (Lord Knight, Champion, Sniper, etc.).
* **Use `@autoloot`** to avoid missing Skull Coins in messy loot piles.
* Skull Coins are also included in:
* **Daily Attendance** rewards
* **Casino** special prizes ([Slot Machine](/mechanics/casino.md))
* **Seasonal event** turn-ins (Christmas, St. Patrick's, Valentine's)
