Combat Luck

[Demigod]

Is it aloud to purchase more then the listed level of Combat Luck (3/3)
if it is is it per level ...1 level gives 3/3, 2 gives 6/6 or can you buy it at any level you want ...its not a power as it is shown its a talent...?

[Steve Long]

The description of the Talent discusses buying it more than once.
