Jewel



Rare and precious, Jewels, sometimes called Gems in the Catacomb Adventure Series, are useful items that upgrade the Crystal Sphere. Each one covers the denizens of different areas, and will give you their position on the Sphere if they get in range. Without the Jewel, those associated enemies will not show up on the Crystal Sphere at all, so finding them can be extremely helpful.

In almost every game in the series, there are multiple gems of every color hidden away, so if a player misses one in an earlier level, there is a chance to get it again later.
