Crystal Hour Glass



Unique to the Catacomb Adventure Series, the Crystal Hour Glass is an incredibly powerful find. It is a magickal artifact that, when picked up, stops time for all but Petton Everhail until all 100 grains of sand have flowed through the Hour Glass (around 30 seconds of real time). While time is stopped, enemies are frozen, but the player cannot directly hurt them either - any Magick Missiles fired off will hover in place until time resumes, at which point they will fire off normally, allowing you to leave a volley of projectiles as an unpleasant surprise for your enemies when the time stop ends. The spell works with Zappers, and Xterminators as well, allowing you to leave these in enemies' paths. Unfortunately, the Catacomb Adventure Series does have a projectile limit, which does somewhat limit how much one can abuse this potent item, but it can be remarkably effective nonetheless, both for evening the odds against a large group of enemies and running through dangerous areas.

While time is stopped, the player is effectively invincible unless they bump into an environmental hazard (such as a Barrier or burning Treant). The player can also pick up items, use Cure Potions to heal themselves, or open locked doors while time is stopped, though the usual pick-up jingle won't play.

Unlike all the other spell items, Crystal Hour Glasses are used immediately and not added to the player's inventory like spell orbs or potions. The player must grab them and use them as they come, rather than pick them up and save them for later. They're also extremely fragile, like many treasures in the Catacomb Adventure Series, and will be destroyed if shot.

Important Warning


The Crystal Hour Glass, while incredibly powerful, also screws a great deal with the game engine. Saving a game while a Crystal Hour Glass is active, or loading a save of a game with an active Hour Glass can render the game unwinnable - if the player somehow manages to get the time stop effect to never wear off, it becomes impossible for players to destroy breakable walls, and effectively it prevents the player from being able to get any further in the game.

The manual even cautions about this: "When you find one of the rare Hour Glasses, save the current position of the game before proceeding to experiment with a time-frozen world."

The effect is mostly avoidable by not saving when a Crystal Hour Glass is active.

Trivia

 * A similar power is present in Sand Trap, the final game in the Apple II line of Catacomb games.
 * The Crystal Hour Glasses and their function pre-dates the bullet time features of later games like Requiem: Avenging Angel, Max Payne and F.E.A.R..
 * The effect of the Crystal Hour Glass, with the player leaving projectiles to hit the enemy when time resumes is similar to the time stop ability of The World in Jojo's Bizarre Adventure. Interestingly, Stardust Crusaders came out around the same time as Catacomb Abyss.
