Lux

Lux are light particles which appear in Kingdom Hearts χ. They can be gained by defeating Heartless and are used to rank the players on weekly basis resulting in more and rarer prices the more the player collects.

There are several factors that can influence the amount of the collected Lux. For once every assist card can raise the drop rate by a small percentage which depends on its level. Five times a day "Lux Up Time" occurs lasting one hour and automatically doubles the Lux earned in this time. Another factor is the Lux rate that is settled at the end of the week when the five Unions are ranked. The Unions on the first three places stay at 1.0 while it's increased for the two last ranked Union to 1.1.
