I don't know if this is intended. Singleplayer. PC-Version.

It is possible to sell the "Barrier Removal spell". I tried to sell other scrolls before and realized that some won't be displayed in the trading-ui. So I thought I could sell all visible ones without any trouble. But I was wrong...

I invested hours to journey through the lands, because i didn't want to watch a video-guide. But I had to.

Luckily it was sold to a generally visited merchant.

It would be nice if all Quest-Items would get an glowing aura (while looting, or on the ground), got put in a special quest container or bag, wouldn't weigh anything (at least in the container), and couldn't be sold. After finishing the dedicated Quest they should be destroyed or the player could be asked if he wants to.

Keys? Are you serious? Managing keys in the inventory is only fun in the SM-Club, if at all.
