Sorry if I missed it in another post somewhere but would like a little clarification. I have used two blue crystals on the yellow ice fiend looking guy and both times it said he feels a little better. How many do I have to use on him? I used them at different times was that a bad idea? If it does take x amount of blue crystals can I use say a few today and a few tomorrow and still add up or does it have to be within a certain amount of time. Thanks for your time.
