Aion 2 Soul Bind Guide: Best Stats, Transfer System, and How to Save Kina

Summary

In Aion 2, Soul Binds are, alongside the pet wheel, the most build-defining system in the game. The same piece of gear can make your character vastly stronger or weaker depending on the quality of its Soul Bind stats.

This guide will teach you exactly how to understand Soul Bind stats, transfer them efficiently, roll the stats you want at the lowest cost, know when to stop, and how to wisely Aion 2 Kina buy to fund the entire process without wasting your currency.

1. First, Understand: What Is the Best Stat for Each Slot?

Every piece of gear has a "Reset" tab in the Soul Bind interface where you can see all the stats that can roll on that item.

Key principle:

Every piece of gear has at least one "Best in Slot" stat. That is what you chase first.

Best Single-Line Stats by Slot

Advanced: Build-Defining Decisions

Once you have that one best-in-slot line, the next step is build-defining choices:

Are you going offense or defense?

Are you stacking passives?

There is no single perfect set for every class

But the baseline is: every gear piece should have that one best-in-slot line.

2. Two Ways to Reroll Stats: Which Is Worth It?

Method One: Direct Reroll (Not Recommended)

In the Soul Bind interface → Sync → you can consume yellow gear to randomly change one stat into another.

Problems:

Chance for a perfect stat is only 1.1%

Extremely low probability, extremely high cost

Absolutely do not do this

Method Two: Transfer System (Highly Recommended)

Core idea: Roll good stats on a low-level yellow item first, then transfer the whole thing to your high-level gear.

Why it's better:

Binding one yellow item gives you 4 chances to roll the best stat

Once you get a good roll, transfer it over

Compared to rerolling line by line, this saves massive amounts of money and time

3. How to Use the Transfer System

Prerequisites

The target gear (what you're transferring into) must be higher level than the source

Example: 36 cannot transfer to 36, must be at least 37

You need a Transfer Stone

Found in the Substance Mall by searching "transfer"

Each Transfer Stone requires sacrificing one yellow item

Step-by-Step Process

Go to Enhance → Transfer

Select the target gear (the one you want to keep)

Select the source gear (the one with good stats)

Confirm the transfer

Important Warning

Enhancement level also transfers over

Example: Source is +7, target becomes +7

Likewise, +13 becomes +13

4. Save Money by Enhancing Low-Level Gear First

This is a trick experienced players are already using.

The Principle

Low-level gear costs fewer enhancement stones and less kinah to enhance

You can enhance low-level gear to +15 first, then transfer it over

This makes your high-level gear instantly +15

Cost Comparison

Conclusion: Enhancing low-level gear to +15 isn't cheap, but it's far more cost-effective than enhancing high-level gear directly.

5. How to Allocate Yellow Gear

Gear Worth Transferring

Yellow gear from Shugo events, open world drops, or the market

Good stat rolls → transfer to high-level gear

Slots That Cannot Transfer: Accessories

Key limitation:

Accessories (rings, necklaces, earrings) cannot drop from open world or Shugo

They only come from dungeons, crafting, or field bosses (extremely rare)

Transfer system does not work on them

How to Roll Accessories

Use the leftover yellow gear that rolled bad stats to reroll accessories:

Rings → Extra skills

Necklace → Combat speed

Rerolling accessories is expensive, but it's the only way.

6. When Should You Stop?

Don't Reroll Single Lines Right Now

Currently not recommended to reroll individual stat lines with yellow gear because:

Each reroll costs around 900,000–1,500,000 kinah

Each reroll has only about a 2% chance of the desired stat

Extremely poor value

It Will Get Better

Hard mode dungeons are coming

Hard mode will drop Sync Stones

Sync Stones can reroll Soul Binds, and they drop in large quantities

Yellow gear prices will drop dramatically as a result

What to Prioritize Now

Perfect your Arcana cards (use energy and order energy for transcendence)

Ensure every gear piece is at the current max item level (86, like Horn Den)

Wait for hard mode

7. Final Steps: Locking In and Enhancing

Only after you are 100% sure you won't change your Soul Binds anymore should you do these final two steps.

Step One: Increase Sync Rate

In the Sync tab, use books to increase the sync rate

Higher sync rate = stronger Soul Bind effects

Also slightly increases combat power

Note: If you still have 1–3 stats that aren't ideal, do not do this yet.

Step Two: Use Philosopher's Stones

Once sync rate reaches 100%

Weapons use 2 Philosopher's Stones to add an extra Soul Bind slot

Example: A crafted weapon with 5 slots → becomes 6 slots

Critical Warning

The extra slot from Philosopher's Stones does NOT transfer!

Replacing the weapon or using the transfer system → the slot is lost

The crafting menu explicitly warns you

Same applies to armor and accessories

How to get them: Season shop, 30,000 season points per stone

Recommendation: Only use Philosopher's Stones when you are absolutely certain you won't replace that gear.

Summary: Soul Bind Optimization Roadmap

Core principles: Transfer first, reroll later; confirm first, lock in later; Philosopher's Stones last.
