This is very impractical idea . Instead of working as shortcut ,it makes even more difficult for you to deal with most circumstances .
You clearly do not understand what "your magic " is .
Your magic is combination of will and energy which are channeled in some idea,image ,object or into something .
You can simply channel those ,without using any objects .Of course you still have to concentrate ,no slacking is allowed .
No object is stronger than your own itent and skills .
Furthermore most objects of power ,mojo bags ,chamrs ,talismans ,amulets and any other sort ot tools sould be recharged at some point .
There is not such thing as charging an object once and for all time , to do all the work instead of me while I am napping on the sofa .
What makes objects special is you and nothing else .
Your tools are as good as their master is ,and work as much as you do.
