Hm... I will have to take back this statement: Seeing as I can't work with game mechanics as my WEAPON would be in a story.

I can work the Elemental weaknesses and strengths of the creatures, some of the items into the story (Ink is one of the items), and other things. What I cannot incorporate are like the AI script like that found with Cactuars of FF7, I might use the statistics in some fashion. (Although, I don't have a clue how to deal with the items and Gil that the creatures drop.)

So, could I work Elemental weaknesses and strengths into Onyx WEAPON? I already mentioned that I could make it immune to Earth-based magic, I could also make it immune to Water-based magics as well as making it weak to Ice-based magics and have it absorb an Element like Wind magics. Would those work?
