Looks like I've got to roll out another bugfix. I don't know what happened with Shield Scorch, but it had three different problems that all needed fixing.
The Phantom Flame issue is the same one as the Berserahna. It'll be the one thing I can't fix this patch, though I do have an idea for a potential fix that will at least work with the Phantom Flame.
The Lunar Hat is deprecated, I forgot I even mentioned it. Oops. Will fix that too, no sweat.
Dill's Message SHOULD be gone. I'll set it to be removed properly, and it'll also leave the inventory when you talk to Fremani again in Highfort.
Bosses are going to get tougher and tougher; you may have to use your potions. On the bright side, the bosses you mentioned in this post all have an item behind them that'll be very useful in saving up potions.
