Thanks for your answers. Well, I think I looked for the Heal potion through out the game and didn't find any. If it really was in the same place as the scroll I couldn't say. I didn't get it. And it's not mentioned in the GB walkthrough either. And the existence of a heal potion isn't even listed. See
here
I think I invested quite a lot in the use magic item (I think this is what was called) ability but I still couldn't use the scroll (yes, it was identified

). Anyway, I'm not going to play the game again just to find this out.
Lord Plothos, I'm taking advantage of this topic to ask you another question.

I finished the game without a fight. I went to the locked level, I sent my rogue sneaking her way to the throne and stole the jewels from there. Cutscene-end game. Were you able to do this? I talked to some friends who played the game and they don't remember being able to end the game like this.
