Why Nameless? I may be wrong, but I run FSC in Deadshot. Normal, Shadow, VH bonus to Undead, with the exception of...20? monsters, everything there is undead. Elemental is dished out from 12? REd Rovers? What else deals Elemental? My Deadshot hat has fire med UV, pants have fire high UV, when I wore the hat with the Volcanic demo suit, I got a max of 4-5 seconds of fire. Before I got high on the pants, I had low, and I took from 5-6 seconds of fire. Not run yet with high on the pants, but I only assume I will get 4-5 seconds of fire, If I remember correctly, I was taking 4-5 with a full Volcanic demo suit, so these numbers seem all skewed to me.

Either way, educate me, should I look for a fire max on one piece and some elemental on another, get fire on my nameless hat and drop the deadshot? I run a CTR and ASI trinket with my Deadshot setup.

As far as guns, I carry a Polaris, a Plague Needle, or whatever the 5* version is called, either the 4* Blitz until I heat it up or a DA and a shiver or Vortex for Slag guards. They tend to walk right out of the vortex though, sadly. Shield I use the Crest of Almire.

Well despite coming from gunslinger lines the deadshot set doesn't really have anything to do with guns, it's just all purpose anti undead gear and the slag walkers of fsc are generally the easy part, the meat and potato cannon fodder with the predictable avoidable attacks, and very little shadow damage appears in the vanaduke fight itself compared to the whomping big normal damage or the occasional bullet phases of elemental. Even if they're outnumbered by the undead 20 to 1 the real threats in fsc are the multi trojan spawns and fire status, wither it's delivered by a puppy or slag or getting bumped into lava by trojan knockback or whatever, so generally any set with normal defense and fire resist is good for fsc, but the goal when playing is to kill everything without getting hit so sometimes compromising 'okay' defenses for increased killing power from weapon specific sets are preferable, like the resistless nameless set. Nameless lets you gun down any monsters faster in any stratum and normal/elemental is still the broadest coverage of damage sources outside fsc and in the vanaduke fight itself. The crest of almire is probably the best shield for the citadel levels and volcanic plate is probably the best shield for the vanaduke fight itself and the grey owlite is arguably best in any t3 stratum outside fsc but still really good in fsc.

I would say Polaris and Argent Peacemaker/Blitz Needle/Plague Needle if you can only afford 2 weapon slots. Polaris because you can keep enemies at range, and Blitz/Plague for Vanaduke and Trojans. If you can afford 3, add Shivermist, if 4 I would say that you carry Polaris, Argent Peacemaker/Valiance, Plague/Blitz, Shivermist.
