75fcr VT always worked great for me on d2lod. Even better if friendly nabourhood AMP nec.
Epic defense vs AA and blindspot hammers, epic offenve vs anything else. Epic absorbs, res and DR% combined with max block. Dont forgete wisp so u can jump hammers with correct timing, even though im unsure how effective that is in d2r.
Else 3hybrid tele zon worked great as well, 1 fury and merc is gone, psn and kb combi annoying AF. Plague, cs, bolt, fury, ga, multi, strafe (i guess impale also now). Bring infi merc urself. And if skillbugged Far cast still works, that can be used as well.
Hammerdin has some strenght and some weaknesses. But a skilled hammerdin can kill most.
BVC is always fun!
Kinda depends on what BM as Belarathon says.
