|An exquisitely crafted sword. Its blade is so sharp that it can cut through space itself.|
However, the extra attacks from Manifold Assault only proc when there's more than 1 target on the screen. Therefore, a +9 branded demon blade will outperform this weapon against single targets. That being said, the autumn katana shines against multiple opponents (as it can hit up to 4 extra targets at once).
The spell Manifold Assault still works with this weapon ("Space folds impossibly around your blade!"), allowing you to sometimes get one layer of recursion.
- Prior to 0.28, the autumn katana had the vorpal brand and clarity instead of the ability to cast Manifold Assault. It also gained 1 base damage, but lost riposte. Note that the game falsely states it has the vorpal brand in 0.28 and 0.29.
- The autumn katana was added in 0.10.
