Some suggestions about fusing;
Destroying a colored item should give the color kit back.
I think it would be nice if there was a way to 'extract' power from a item without destroying it, for example if i had an item with 10000 more power than the max power level is.
Maybe an option to turn a fused item into power kits, for example if i have one highly fused item but i wish to use it to upgrade multiple items.

Thank you i added a poll so you can vote for it now
