Flame Clock

Flame Clocks are objects in Xenoblade Chronicles 3 mounted on Ferronises. Both Keves and Agnus fight each other fill their respective Flame Clock.

Description
Keves Flame Clocks are blue, while Agnus Flame Clocks are greenish-yellow. The Castle's Flame Clock are both colors. Those bound by Flame Clocks must kill other lifeforms to fill it up to survive. If the Flame Clock becomes empty, every human bound to it dies. If the Flame Clock is destroyed, those bound to it are freed from its system, no longer required to take lives to stay alive. Kevesi and Agnian humans are typically bound to the Flame Clock system, although it is possible for a naturally born human from the City to be bound to one in Shania's case. Flame Clocks are extremely durable, not even an Ouroboros form or even Moebius is able to dent it, the only known weapons capable of destroying Flame Clocks are Lucky Seven, Monado Replica EX+, the Aegis Swords and A's sword.

The only known ways to free humans from the Flame Clock is by its destruction or becoming Ouroboros, although they are still bound to their ten year lifespan.

Gameplay
For the majority of Chapter 1, the party is bound to 's Flame Clock. Its Flame Clock can be filled by defeating enemies which also increases the party's stats, but the Flame Clock will also deplete over time or the player loses a battle. If the Flame Clock is below 25%, the Flame Clock Low, Attack Down will be applied. Once Moebius is defeated, the party is no longer bound by the Flame Clock system.

Destroying a Flame Clock will liberate a Colony from the control of the Consuls and the party will be able to visit them, but destroying a Flame Clock will also raise the Warning Level of each nation.
