Diablo 1 HD Hellfire Mod | Awake

What is the best slot for mana leach on a rogue? I am looking at alot of the uniques in the documentation and none of them stand out other than The symbo lof Rathma.

just wondering because I just found LADY ZENOBIA'S WAR DIADEM

I take it a crafted ring is a best bet here for maximizing my dps.

items on my list to get :

Giant skull grim helm (for transformtion, which char uses this best btw)

Vampire Gaze Grim helm

Ceremonial Mail (for insane dps)

MICTLANTECUHTLI, THE DEMONBLADE for the transformation again

are there any good set items I am overlooking?

I also have a windforce..what are thoughts on switching weapons every time I almost run out of mana?

I would say best would be a mana leech ring
with res/stats/life and or critical damage/hit recovery speed

something like this, I use on my rogue

You just need enough mana leach to keep mana pool charged through a mob and boss battle. Critical damage bonus and extended damage bonus will greatly help. I find my Rogue needs anywhere from 6 to 8% mana leach minimum. As all other classes, the fastest weapon and attack speed bonus is what really counts.

well I am using hearthseeker which only has life steal..and I think the ring slot is the best place to have mana leach to maximize my potential dps from other gear slots

Hearthseeker seems to be the best bow in the game so far.

Some Scout and Harbinger bows have crafted pretty well and were able to get me through Nightmare. But once you reach Torment, you must have weapons with [Ignore Target Defenses] to get past the bosses.

my rogue is level 54 and I am grinding for 60 in torment to give you an idea of how far along I am

For rogue most important thing is to ignore target's defense, attack speed, dexterity, resists, strong golem and Life + Mana Leach. Now my third rogue has reached the 13th floor tornment reaching level 45 and fully dressed up by her older sister.
That what she's wearing can be found here: https://www.youtube.com/watch?v=W-O0-S1Y4X8

well.I don't have any high level craftable ring patterns. what are the names of tier 3/4 rogue/assassin craftables

only ones worth making are level 50 recipes (lower ones have lower stats)

offensive
fanatic=assassin cc/maxres/str+dex/4(or5?) random affixes
conqueror=barb cc/str/+dmg done/4(or5?) random affixes
harbinger=rogue cc/dex/+dmg done/4(or5?) random affixes

defensive
guardian=warrior armor/vita/-dmg taken/hit recovery/4(or5?) affixes
