Hi @Aeseiri.
I don't use meds anymore ever since the change that broke some functionality. Plus 20 years of making builds I don't really need it myself. Real life my time's pretty busy, so I won't promise anything but if I have opportunity and a few weeks I might get around to updating the build function for my previous builds.
As far as hell on Earth, slotting for demons for me is idiosyncratic, as I almost always forget to activate it as frequently as I should so it became a slot mule for unique IOs. Based on how many extra slots you have available you can always throw some recharge in there. As it is currently slotted no, you are correct, it would not be a very frequently, it is off enough for me to use on important fights with some of my global recharge.
