Whenever a power is used directly on you, you gain a single charge for that power. These charges may be used as a single-use copy of the original power. For powers that run continuously, the time you spend being effected by the power determines how long the charge gained will last. You may use one charge to give another charge a +50% boost, and this may be used repeatedly to a 10x boost to a power, in any direction of growth that you desire. You can gain a maximum of 3 charges of the same power per hour, but different powers have separate counters. There is no limits on how many charges you can have.
