I honestly have no clue whether eleth would fall into either category for Accelerator. Technically it is magic but if you don't have eleth then you ... die. Basically it's kind of a poorly defined type of life energy that if it is not present, then everything just dies a horrible lingering death. So Accelerator may or may not be affected, but if he was affected and it came out because of that, Asbel would be kind of BUT YOU'RE NOT ... DEAD ... so yes.
