Cleric Subclass: Fate Domain

The Fate Domain focuses less on personal glory, but to see the outcome of an event, and to push it more favorably in the cleric and their ally's favor.  As such, the subclass' primary focus is that of rerolls as opposed to flat outcomes based on previous rolls as with the Divination wizard.

As such, the Fate Domain cleric takes on a more support role, similar to the Life Domain cleric, throwing aside personal glory to make sure others can live to see another day, or perhaps become more heroic than they already are.    Beyond this, the fate domain cleric has access to powerful tools for gathering information ahead of times, or on specific person or places, without the cleric being forced to choose between said options, or potential healing and damage.
