Took what feels like about a week of slaughter, but I finally coaxed one out of the little bastards.  Also got Aerianna from 80 to 87 in the process, as well as lots of random deaths; some due to my carelessness, but most because random throw stone and hidden smite stuns are just that awesome when you have 3k HP and no peno (probably my next target u_u).  Now I just need a decent valk shield for it.
