Aion 2 Theostones: what they do and which one to engrave
NCSOFT / AION 2 game art
TL;DR
- A Theostone gives your weapon or guard a chance to trigger an effect when you attack: extra elemental damage, damage over time, or a control effect such as Stun.
- Only weapons and guards have a Theostone slot, one each. Two identical stones do not stack.
- For PvE, Grobs, Madsin and Kanon agree the effects are worth very little. Engrave something cheap and move on.
- For PvP, the control effects matter. Stun, Paralyze, Root and Seal are the ones to look at.
- Theostones are lost on a Gear Transfer, so keep the expensive ones for final weapons.
How Theostones work
Theostones are engraved from the Theostone tab of the Enhancement menu. In the data, every weapon and guard has 1 Theostone slot and armor and accessories have none. That fits FRESHY's routine of putting one on both the weapon and the guard.
Every stone has the same shape: a percentage chance on attack to trigger one effect, then a short internal cooldown.
| Stone type | Internal cooldown |
|---|---|
| Damage | 1 second on almost every stone |
| Control | 5 seconds |
The item text adds one rule: when identical Theostones are engraved, only one of their effects applies. Use two different stones on the weapon and guard.
Engraving a new stone over an old one replaces it, and the game warns before it does.
Creator tip
The Theo stones is what makes your weapons glow like this. Now, Theo stones are always structured in the same way. You always have a chance to apply a certain effect.
What the grades do
There are 17 stones at each of Rare, Epic and Unique. The higher grade of the same effect type has a longer or stronger effect. Some examples from the data:
| Effect | Rare | Epic | Unique |
|---|---|---|---|
| Single-target Fire damage | Zikel's Vestige: 1% chance, 5,000 | Traufnir's Courage: 1% chance, 10,000 | Tiamat's Rage: 1% chance, 15,000 |
| Poison over 20 seconds | Santras's Secret: 5% chance, 300 every 2s | Orissan's Blood: 5% chance, 450 every 2s | Zikel's Arrogance: 5% chance, 600 every 2s |
| Stun | Aulak's Roar: 3% chance, 1s | Fasimedes's Dignity: 3% chance, 2s | Meslamtaeda's Greed: 3% chance, 3s |
The other effects follow the same pattern: Water, Earth and Wind damage, single-target or against up to 4 targets, Bleed, Blind, Root, Paralyze, Seal, and slows to Move Speed or Combat Speed.
Which one to use for PvE
Creators do not spend on Theostones for PvE. A few thousand damage on a rare proc is small next to a full rotation.
Creator tip
Now, for PvE, those are completely useless because the damage is so low, it is really not relevant.
| Creator | PvE verdict |
|---|---|
| Grobs | Useless, because the damage is so low |
| Madsin | Last of every system. Poison stones performed best early, but all are mostly irrelevant in the long run |
| Kanon | Under 1% of total damage |
So for PvE, pick a damage stone you already have or can buy cheaply, engrave it, and spend your Kina elsewhere. Grobs's advice is to pick whatever looks good to you.
Which one to use for PvP
The control stones are why Theostones exist. Grobs points to a 2% chance to Paralyze for 2 seconds as the kind of effect that changes a fight against players. At Unique grade, Ereshkigal's Honor paralyzes for 4 seconds, Nezekan's March roots for 5 and Beritra's Conspiracy seals for 5.
Unique control Theostones
Getting and combining them
Unbound Rare stones can be traded, while the Epic and Unique stones cannot. Combining turns spare stones into higher ones, and the game shows the result chances before you combine:
| Combine | Result |
|---|---|
| Rare stones | A random Epic stone |
| Epic stones | A random Unique stone |
| Unique stones | Another random Unique stone |
