Humming Power Crystals come from the Fragmentizer.</p>
<p>The fragmentizer can turn items in your inventory to crystals, which you can then use to buy items from the Crystal Shop. You can fragmentize any restockable (i.e rarity 1-99) item. Fraggable items will show as clickable pictures when you&;re at the Fragmentizer.</p>
<p>Not all fraggable items will always give you a crystal - it&;s based on rarity. If you use common, mundane or normal items I recommend you only use VERY cheap ones, as you&;re likely to get no more than three crystals per ten items.</p>
<p>If you&;re fragging multiples of the same item, you do NOT need to click back every time; you can just keep hitting Refresh till you run out of that item.</p>
<p>R65 and under: 0-1 crystals
R66 - R89: 1 crystal
R90 - R98: 1-2 crystals
R99: 1-3 crystals</p>
<p>To spend the crystals, they need to be in your crystal bank (there&;s also an achievement for having 1000+ crystals in your bank). They cannot be removed from the bank, only spent on crystal shop items.
