Red Crystal is an object in Chrono Cross. Appearing in Fort Dragonia as part of a puzzle, the Red Crystal is blocked by several bottomless gaps in the floor. It appears a prism-shaped crystalline column comprised of an unknown red substance. To reach it, Serge must rotate the dragon statue above it to the East. Two chests are located near the Crystal, as well as a Red Record of Fate, which replenishes Hit Points. Guarding the Crystal are two Cybots.
Along with the Blue Crystal and the others, the Red Crystal must be deactivated in order to reach the area where Lynx and the Acacia Dragoons are preparing a ritual, using the Dragon Tear, so that their Demi-human leader can switch bodies with Serge.
