Sure, I can help you with this. Just tell me what to do, and I will try my best. Although I have been busy with writing multiple threads to the Official RS Forums (including a quest suggestion), I can still help you with this.

My idea for the upgrade system of crystal items is that in order to turn them into level 100 equipment, one would need two types of items: plenty of uncommon, stackable drop, that almost everything in the dungeon drops (higher-level monsters and bosses in higher quantities), and an item only dropped by the boss (how rare the item actually is and how many such items one needs to upgrade the crystal weaponry is all up to you).

As for the look of the boss, I have no idea. You should specify what kind of boss you want it to be before I can give any ideas for its appearance. Perhaps you could use the Statue of Guthix in the dungeon as an inspiration for the boss monster?
