I still cannot understand the recent addition of Life Steal/Drain (or whatever you wish to call the trait). It seemed like it would be a lich casting a hex (to mechanically accommodate a horrible HP pool), but apparently vampires have this as well. It must not involve blood if glykins aren't immune and it doesn't harm the recipient.

So what/how exactly are vampires and liches performing for this?

If blood is irrelevant, then is it draining focus? If not, what?

Whatever it is, is it a form of feeding for a vampire?

Why is it that only vampires and liches can perform this?
