You'd need need a high level Banish for that (or at least a high level character to make that dust work). That's rarely a thing for a solo and I mostly play those :(
Casters don't need it (since Jan-Ette is easiest for the Shield and the Sword can't be used). Fighters can take ages to wake up and get around to killing another ghost. If I go for the Light Sword I do that early, level 10 or 11. Maybe I'll give it a shot if I get there with a solo Samurai or Lord. Then again I never found the Hut too troublesome.

Now that I think about it I probably won't do that with Lord/Samurai either since I did that with my Fighter & Bishop. Maybe if I come around to playing some mod. Any good experiences with difficult mods? As is it makes no sense to go for the most powerful solo characters anymore as I did that already. Light weaponry, even just one of those, renders any character a monster after all...

In my current playthrough, I just went to Bayjin and got the VapoRizer and guess what showed up in the chest? (Hint: It's a shield whose name rhymes with "Right".) Again, I'm not going to use it as it seems to be overpowered for me.

No, I did not reload the chest for better loot. I also left Jan-ette there without talking to her; maybe I'll come back later.

Incidentally, I also got a Mystery Ray. Maybe I should play with it and see how it works.
