How to apply a Seed Sphere

The process of inserting a Seed Sphere into a socket item is one of the key steps in the socket system. By doing this, you transfer the Seed Sphere’s attributes to your weapon, armor, or accessory. Below is a step-by-step explanation of how to complete the process.

NPC Seed Researcher

Seed Researcher Location: Elbeland (50, 242)

The Seed Researcher is the NPC responsible for adding and removing Seed Spheres from your socket items in MU Online. It also allows you to mount a completed Seed Sphere into a socket item, granting unique options that enhance combat performance. This NPC is located in Elbeland, at coordinates (50, 242). The Seed Researcher plays an essential role in the socket system, as it lets you fully customize your equipment — adapting it to an offensive or defensive playstyle depending on the Seed Sphere type you apply.

Required Items to Insert a Seed Sphere

Result: The item will receive the attribute of the inserted Seed Sphere.

Seed Sphere Compatibility

• Defensive Equipment (armor and shields): can only use Water, Wind, and Earth Seeds.

How to Insert a Seed Sphere

1. Go to the Seed Researcher in Elbeland (50, 242).
2. Select the option “Seed Sphere Application” or similar in the NPC menu.
3. Place the Season 4 item with sockets you wish to enhance (it must have at least one open slot).
4. Insert the compatible Seed Sphere you want to apply.
5. Add the required items: Jewel of Creation and Jewel of Chaos.
6. Select the available slot where the Seed Sphere will be placed. (The order matters for Bonus Socket effects.)
7. Click on Application.

Bonus Socket

The Bonus Socket is a special enhancement that can be activated on socket items when you insert 3 Seed Spheres in a specific order.
If the correct sequence is achieved, the system grants an additional bonus option to the item, with a 30% success rate.

• Requires 3 socket slots filled with the correct Seeds.
• The insertion order is critical — changing it disables the bonus.
• If successful, the item gains a unique extra bonus.

Bonus Socket – Examples

Item	Seed Order	Bonus Obtained	Success %
Sword / Axe / Mace / Bow / Crossbow / Scepter	Fire / Lightning / Ice	Attack Power Increase +11	30%
	Lightning / Ice / Fire	Skill Attack Increase +11	30%
Staff	Fire / Lightning / Ice	Wizardry / Attack Increase +5	30%
	Lightning / Ice / Fire	Skill Attack Increase +11	30%
Helm / Armor / Pants / Gloves / Boots / Shield	Water / Earth / Wind	Defense Increase +24	30%
	Earth / Wind / Water	Max Life Increase +29	30%

Important:
If you use the same Seed Spheres but in a different order, the bonus will not activate.
Even with the correct sequence, the Bonus Socket only has a 30% success rate.

Socket Package Option

Socket Package Options are special bonuses that activate when your weapons and armor with sockets contain specific Seed Sphere combinations.
These combinations grant additional attack or defense effects, depending on the item properties involved.

Note: For the effect to activate, all sockets from your full set and weapons are considered.

Combination	Seed Types	Option	Success Rate
All Seed Sphere Types	Fire (1), Water (1), Ice (1), Wind (1), Lightning (1), Earth (1)	Double Damage Rate Increase +3%	100%
Specific Combination	Fire (1), Water (3), Ice (1), Wind (3), Lightning (1), Earth (2)	Opponent’s Defense Ignored +1%	100%

Destroying a Seed Sphere

1. Go to the same Seed Researcher in Elbeland (50, 242).
2. Select the option “Seed Sphere Destruction”.
3. Place the item that contains the Seed Sphere you wish to remove.
4. Select the slot that contains the Seed Sphere and click Destruction.
5. Confirm or cancel. Depending on the server, there may be a risk of failure when destroying the Seed Sphere.

Note: This process destroys the selected Seed Sphere from the item, but in some servers, it may be possible to extract it safely.
