Just a quick question here.

The Blade of Four Energies (in Secrets of Magic) doesn't have a listed DC for the spells it casts, nor an attack roll for the one that requires it. The greater version does have a DC (but still no spell attack, though I assume it is about +28). I can't find any errata about it.

Is there an accepted value for this item or do I have to figure it out myself?

Just a quick question:

What happens if a gunslinger uses an ability that misfires on a failure (say, Alchemical Shot) with a crossbow? I assume it automatically is a critical failure, but do they have to spend the Interact action to fix it? Or is that just firearms?
