Hey yall, I picked up D2R recently after two decades passed since my last log in into classic. I’m currently enjoying the game playing amazon using lightning jav build I found online. I quite like it and everything was peachy even in nightmare which pleased me greatly however I’m having a difficult time now in hell.
Because everything being lightning invulnerable I was barely able to kill the blood raven (all zombies and skellies immune), I pretty much just ran through most of areas from teleport to teleport only killing what I need for quests but now I’m truly stuck on Andariel. Lightning invulnerable afflicted swarm me all the time, my merc and valkyrie can more or less deal with regular immune mobs for me but but when an unique one + adds comes they just reap right through them and take me to poundtown.
What would be the better option to do now for possible getting some better runes and gear, go back to nightmare or stay in hell? My luck never fails me so I have zero recommended gear even easier ones like razortail, titan’s or aldur’s and I’m nowhere near completing smthing like infinity for merc or CtA and CoH for myself. I have runes for spirit shield but I don’t haven’t found a monarch shiled for it yet.
