I read on the wiki that after Harkon is defeated on the vampire side there are suppose to be chalices you can take, does anyone know where to find them?

There is only one bloodstone chalice but stuff you add to it, to make the affects last longer, like vampire ribs, or vampire leg.

I know about that i already have it to the 5 day duration, what i meant is that somewhere in the castle is a chest with two chalices apparently meant for aesthetic detail, which only appear after Harkon's defeat.

I found one in the Chest next to the door in the room where you fight Harkon.

If you drop it, it just floats in the air you can only take it back again, you cant move it. So you wont be able to decorate your home with it.

I dont think it was intended to be taken.

So can you jump on them?

I think you can, but i only found one.

Yeah. Welcome to the new "Floating Paint Brush" of Skyrim! Have fun climbing to the top of White Gold Tower!
Hmmm, wonder if you can reach Skuldafn with this...

Could you post a link to the wiki article
