Maybe try a few 5x NM kills in Morimar, and work our time down til we start finding ourselves face to face with the boss? From the BG Delve Thread (group who killed all 5 NMs + Boss with 10+ mins to spare) :

I hated when people posted numbers and talked about winning just hinting at stuff, so here it is.
