I would like to create a character that gains his powers in an unnusual way. I just need some help in figuring out about what the modifier would be. Right now I am guessing it would be about -1. He gains his powers from a few different shrines, each shrine grants a different set of powers but he may be effected by more than one shrine at a time. To get the powers requires him to go through a challenge, testing something like his strength or agility, the challenge takes about twenty minutes and unless the GM declares otherwise will be decided by a roll on the appliable stat. If the power is granted it lasts for 24 hours, if not he can't try again for 24 hours. This is a tough one when you try and apply it to a power such as energy blast. Any suggestions?

If a person(Lets call him Kiteman) has flight with usable by others, no END and persistant, in a multipower or variable power pool which he then grants to another player(Lets call this one groundboy). If Kiteman switches the flight out will Groundboy loose the ability, or does the effect actually "Give" the player the power?
