Best warlock exotic is apotheosis Veil for the crota encounter.

if u have suros it has health regen and agility

I ment for armour, I have red death.

For Titan, a raid helm that gives you health on orbs and faster melee speed. And Ruin Wings. Haven't looked at Warlock stuff to have a good answer.

Why ruin wings??

What you really want is something that gives you health on orbs (for another method of health regen; never a bad thing) and faster melee speed which obviously helps when attacking with sword. That's covered by that raid helm. Ruin Wings to give you more heavy so you can take down sword bearer if he's being difficult. The fast you take him down, and closer he is to Crota, the more time you have with sword next to Crota.

i would use guns with agility tge faster u move tge less health u will lose i always use agility
