Ancient Hero's Soul Guide – How to Get & Use It (MU Online Season 21)
Ancient Hero's Soul (AHS) is a special material used to unseal Mastery Blood Angel sets in MU Online. If you want to use the powerful Blood Angel mastery armor that you buy with Ruud from Priest James, you will first need to create at least one Ancient Hero's Soul.
• Ancient Hero's Soul is crafted from specific Ancient set items.
• The ancient item must be at least +11 with +16 Life option.
• The Chaos Machine combination has an 80% success rate on most Season 20–21 configs. :contentReference[oaicite:0]{index=0}
1. What Is Ancient Hero's Soul Used For?
Ancient Hero's Soul is a Blood Angel Conversion Mark – it is the key combination material that allows you to turn your Sealed Blood Angel items into usable Mastery Blood Angel armor.
The typical process in Season 18–21 is:
- Buy a Sealed Blood Angel set piece for your class from Priest James using Ruud.
- Create an Ancient Hero's Soul using specific Ancient set items.
- Use the Chaos Machine to combine the Sealed Blood Angel item + Ancient Hero's Soul.
- Result: a usable Mastery Blood Angel item with full set effects and stats.
The unsealing combination has a 100% success rate in the official system; therefore the “real risk” is only in creating the Ancient Hero's Soul itself.
2. Requirements to Create Ancient Hero's Soul
To create an Ancient Hero's Soul, you must sacrifice one Ancient set item from a very specific list of sets and meet the upgrade requirements.
2.1. Accepted Ancient Sets
Only the following Ancient set names can be used to craft Ancient Hero's Soul (set pieces only – not weapons, rings or pendants):
| Group | Accepted Ancient Sets |
|---|---|
| 1 | Vicious / Hion (Hyon) |
| 2 | Aegis / Anubis |
| 3 | Gaion / Muren |
| 4 | Broy / Agnes |
| 5 | Semeden / Crono |
| 6 | Vega / Chamer |
| 7 | Akhir / Carthy |
| 8 | Camill / Inas |
| 9 | Arkadin / Emile |
| 10 | Vesper / Moloso |
2.2. Upgrade Requirements
Your chosen Ancient set item must meet these conditions:
- Item type: One Ancient armor piece from the list above (for any class).
- Item level: at least +11.
- Life option: additional option from Jewel of Life must be +16.
If the item is not +11 or does not have +16 additional option, the Ancient Hero's Soul combination will not appear in the Chaos Machine on most Season 18–21 servers.
2.3. Success Rate
When all conditions are met, the Chaos Machine will show approximately:
- Success rate: 80% to create 1× Ancient Hero's Soul.
Some private servers modify this rate (for example 25%–80% depending on VIP level), but in most Webzen-like Season 20–21 configs the chance is 80%.
3. How to Create Ancient Hero's Soul (Step‑by‑Step)
Step 1 – Upgrade Your Ancient Item
- Choose one eligible Ancient set piece from the list above.
- Upgrade it to at least +11 using Jewels of Bless, Soul, Chaos, etc.
- Use Jewel of Life on the item until the additional option reaches +16.
Step 2 – Go to the Chaos Goblin Machine
Once your Ancient set item is ready (+11 +16):
- Go to Noria and find the Chaos Goblin (usually around 180, 100).
- Click the NPC to open the Chaos Machine window.
- Select the Regular / General Combination option (on some UIs: “Enhance/Craft Equipment” → “Ancient Hero's Soul” or “Blood Angel Soul”).
Step 3 – Add the Ancient Set Item
- Place your +11 +16 Ancient set part into the Chaos Machine window.
- If your server requires extra materials (for example 1× Jewel of Chaos), they will be shown in the combination window – fill them if needed.
- Confirm the combination.
If the mix succeeds, you receive 1× Ancient Hero's Soul. If it fails, the Ancient item and any materials used are destroyed.
4. How to Unseal Blood Angel Items with Ancient Hero's Soul
After you have at least one Ancient Hero's Soul, you can unseal your Ruud Blood Angel gear.
4.1. Buy a Sealed Blood Angel Item
- Obtain Ruud from Mastery Boxes and high‑level events.
- Visit Priest James in Elbeland or Event Square.
- Buy the Sealed Blood Angel set pieces for your class (helm, armor, pants, gloves/boots).
4.2. Unseal in the Chaos Machine
To unseal a piece:
- Go again to the Chaos Goblin Machine.
- Select the General Combination option.
- Place the Sealed Blood Angel item into the window (Combination Material 1).
- Add 1× Ancient Hero's Soul (Combination Material 2).
- Press Combine.
If the combination succeeds (normally 100% success rate on official configs), the sealed piece becomes a usable Mastery Blood Angel set item with full set effects.
5. Extra Tips & Common Questions
5.1. Can I use any Ancient item?
No. Only the specific Ancient sets listed in this guide are accepted by the Ancient Hero's Soul combination. Even if another Ancient item is +11 +16, the Chaos Machine will not allow it to be used for AHS.
5.2. Do I need +11 exactly or +11 and up?
The minimum level is +11. Higher levels (+12 ~ +15) also work as long as the item belongs to one of the accepted sets and has +16 Life option.
5.3. Do I always need to craft Ancient Hero's Soul?
On most official‑like Season 21 servers, yes – you craft it via Chaos Machine using Ancient sets. Some custom servers may also:
- Sell Ancient Hero's Soul directly in the Ruud shop.
- Drop AHS from high‑level bosses or special events.
Always check your server’s guide or Ruud shop to see if there are extra ways to obtain it.
5.4. Is the Ancient item destroyed?
Yes. Whether the combination succeeds or fails, the Ancient set item used as material is consumed in the process.
Conclusion
Ancient Hero's Soul is a small item with a huge impact on your progression – it is the gateway from Ancient gear to the powerful Mastery Blood Angel sets. Once you understand which Ancient sets are accepted, how to upgrade them to +11 +16, and how the 80% combination works in the Chaos Machine, creating AHS becomes a straightforward part of your Season 21 gearing path.
Farm the right Ancient items, craft a few Ancient Hero's Souls, unseal your Blood Angel gear, and you’ll be ready to push into higher mastery tiers like Dark Angel, Holy Angel and Awakening.
