This is a change coming up in future playtest documents.
Instead of having a pool of bonus LUC dice, instead LUC is an attribute which once per day you can use instead of another attribute.
So if you're trying to crack a computer password, you might normally use LOG. But if your LOG isn't great, you can use LUC instead and stumble across the password by accident.
This works in combat, too. A lucky shot, for example.
Some careers/traditions may allow you to use LUC in this way more than once per day.
