So I have had an interesting magic idea which grants the ability to redirect and amplify energy using mana. Obviously this new form of magic will be relatively controlled like say learning a small static shock in the first saints week to a fully coating your arm in electricity.
This is not meant to be a voidal type of magic but more so a self reliant kind of magic using physical and potential energy and converting it into a little ball of lightning which can give you a shock and maybe a little burn. This magic could also potentially be used in a medical way by restarting a heart or something along those lines with risk of harming the patient (a d20 roll most likely)
before i write anything about this magic i wanted to see what everyone else thought about it first and if this is a good idea or already potentially available via a different method or smt.
