Was playing a MoM game tonight and enlisted an Assassin type Hero. Got to preparing an artifact that would give him constant invisibility and ran into a snag. I've got so many spell effects available that some are listed off to the side and I cannot access them. I've included a screenshot for reference.

Is there anyway to fix this problem outside of using the game tweaker to fix the artifact once it's been conjured?

Apologize in advance if my grammar or spelling is off. Allergies are kicking my ass and so is the Benadryll.

Before you make the artifact can you make the window into full-screen first? (its ALT+Enter)

Running DOSBOX in full screen won't make a difference here. There is no distinction from the application perspective whether DOSBox is running in a window or not.

Are you running any modifications to the game? It looks like you've got more spells there than would normally be allowed. For example, Wraithform is a death spell while Righteousness is a life spell. I was under the impression that you could never have spell books for those two areas at the same time. I thought even finding an incompatible spell book impossible.

It looks like your only option is to indeed edit the item through some other means, I don't think the game as released was set up to handle this.

The problem I see is that you've clearly got some sort of mod/hack/cheat going. You've got life & death spell books?!?! This isn't even allowed in the game. You've also got so many spell books from each relam that you've got all the high-level enchantments listed. In a game where you're not mod/hacking/cheating you'll never see this many enchantments listed. Because of that, there is no fix for what you've done. Follow the regular rules of the game and you won't experience this problem.
