Star Ruby

Huge, sparkling red gem.
Found In Terra Cavern B3
The Titan blocking the way to the Sage's Cave won't move until you give him the Star Ruby, which can be won from the Vampire in the Terra Cavern. Apparently he likes to eat expensive gems, which just seems like a big waste to me. But hey, whatever works.
