Anything that boosts intellect for your super (activate it on the way to pick up the sword, trigger invisibility via that, and you save a little time without crouching) or strength for your blink strike (to stay near Crota safely between kneels). Personally I use Crest of Alpha Lupi due to mine's massive strength boost, and my raid/iron banner gear gives me good enough intellect for the first option. However if you don't have a weapon to heal yourself, keep an eye out for Mask of the Third Man so you can heal by picking up orbs. Gives a neat intellect boost, and the melee attack speed increase might make difference-haven't noticed myself.
