Did this today. Think it's a nice little achivement, that i'm not sure anyone has done before.
Basically the strategy was sustaining with blood barrage troughout the raid, and using scavengers as healing points.
Olm was a bit more tedious, as i couldn't slip on olm burst (ie. crystal burst + lightning + olm attack could take me out).
And to those who ask: Yes, i did in fact forget to charge the Sang staff before attempting this.
