i didnt bother reading all the posts, but ive played psn nova necs for a long time now..
imo, in the pvp world in east (or in any realm i hope) a psn necro will really get raped if you had no enigma. necros are the most durable characters out there and 1v1 or teams, without being able to teleport you cant do much. also if youre good, you can strategize where to tele and place psn novas. also, 50% psn damage from bramble isnt really important and the thorns isnt too strong. -psn res is way more important than +psn damage.. this is also the same for light damage characters of course and cold sorcs (aka cold mastery is pierce, - cold res..which basically is what does the damage)..
imo, you should go hoto/08 valk/sojs(or raven pending on who you duel) or hoto/godly circlet (3/20/2 or something close)/fcr ring+soj(or raven).. just a lil to add though.. other than that, not a bad guide for a pure psn nova nec.
