Uitilty Powers?

[melkoriii]

How are the uses of the Utility powers work?

As in I have seen some that are for use in combat. Are they once and encounter, day? Only reactions?

Each one should state what it is.

 

[Mouseferatu]

Each Utility power says whether it's usable at-will, per encounter, or per day.
