How to get it
- Reach southwest Fainweald and activate the Nochtean Gate Beacon.
- Go southeast, ride the elevator to the lower ruins, pull the gate lever, and enter the silver fog of Ravaged Tomb.
- Press the side-gate switch, push the released pillar onto the pressure plate, then open the bone chest by the stairs before the second gate.
- Equip Duality Stone on Axatana or Axe & Dagger only. Other melee weapons do not expose this Combat slot.
For exact puzzle recovery and the side-corridor materials, use the full Ravaged Tomb walkthrough. If you are still in early Fainweald, finish Widow's Overlook and Mushroom Village first.
What it does
| Temper level | Reported light-combo effect |
|---|---|
| Level 1 | First attack in the standing light combo strikes twice. |
| Level 2 | First and second attacks strike twice. |
| Level 3 | The full standing light combo strikes twice. |
That doubling also feeds Resolve faster on those two weapons, which is why Game8 calls it the best Combat stone for Axatana / Axe & Dagger. Pair it with a crit Support stone (Auspicious) or Grudge Stone if you are already on a fast melee kit.
Should you rush it?
- Yes if Axatana or Axe & Dagger is already your main weapon.
- No if you are still on Veteran's Battle Axe, Black Needle, or a slow heavy. Duality Stone will sit unused.
- Temper it after you can feed Tarcore. Level 3 is the breakpoint that makes the whole combo double.
