Powers Players can't see?
So in my campaign each of the PC's got a special power from a secret temple after passing some puzzles / tests.
Making the powers was easy enough but I kind of want my players to discover how to use them not just click on a button on their action tabs. Besides me just manually doing the rolls in secret until they have figured out their power is there a way to create the power but not have it on their sheet or at least not that they can see?
I guess the simple question is there a place I can put the power so I can use it for them?
