Yeah sorry, you said prevents from going below 1hp which sounded like all you had for it. And correct, it doesn't have any utility. Saving Purify for it is what I normally do (Most DRK actually don't know this cause they are the lamers who go for glamour and suck at pvp), but it's hard when you're up against 100 fotm summoners and their insta triple dots that tick for 750+ and deathflare, fester, blah blah that leaves you near dead too.
Living dead is a joke and I seriously hope they rework it.

Also, How are you liking your new server. Was just hitting pvp hard when I met you. Rank 40 now! D:
