The Rubble is an enemy in Chrono Trigger that first appears in the Mountain of Woe in 12000 BC. They are a great source of EXP and TP. They do not, however, respawn when leaving the current screen and re-entering. They have a very high evade, so equipping items such as the Acuity Ring or Berserker Ring is recommended. Every tech and item will be disabled when initiating combat, and the player has a limited amount of turns before they escape.
