AION 2 Theostones: every effect, grade and combine chance
Updated 2026-10-10 · checked against Global launch (client 2.0.5.0)
Theostones give a weapon a chance to do something extra when you attack: blind, stun, root or poison the target, or hit it with an elemental burst. Each effect comes in three grades — Rare, Epic and Unique — and the grade raises the chance and the strength. A Theostone you obtain goes to the Enhancement menu.
Two rules on every stone: each effect has its own activation cooldown, and two identical Theostones do not stack — only one effect of the same stone applies.

Combining Theostones
Theostones you do not want can be combined into a new random one. The input grade decides the odds of moving up:
| Combine | Result grade | Most likely results |
|---|---|---|
| Rare Theostones | Rare 88.88%, Epic 11.12% | Aultross's Promise (Rare, 8.815%); Tassin's Command (Rare, 8.815%); Ulgorn's Will (Rare, 8.815%); Zikel's Vestige (Rare, 8.815%) |
| Epic Theostones | Epic 90.9%, Unique 9.1% | Freyr's Wisdom (Epic, 9.015%); Sif's Knowledge (Epic, 9.015%); Sigyn's Brilliance (Epic, 9.015%); Traufnir's Courage (Epic, 9.015%) |
| Unique Theostones | Unique 100% | Meslamtaeda's Regret (Unique, 9.917%); Tiamat's Rage (Unique, 9.917%); Triniel's Rationality (Unique, 9.917%); Vaizel's Oath (Unique, 9.917%) |
A Rare combine lands an Epic stone a little over one time in nine, and a Epic combine a Unique one about one time in eleven. A Unique combine only re-rolls which Unique you get. Within a grade the effects are not equally likely — the table shows the most common results — so combining is a way to climb a grade, not to aim for a specific effect.
