I'll start out with saying, thank you! This Diablo 2 server is absolutely fantastic. Kudos to everyone who is playing and who is/was involved in making this server great!

I started playing a summoner necro and ended up playing normal up until Act 4, and things were fine til I saw those crazy venom lords there. I made a game called 'act4ishard' and ended up finding someone who helped me get through Norm/NM/Hell and got me some cow runs and going. I greatly appreciated that, but I'm struggling a bit.

I'm currently level 85 and I've been loading some other characters into games to help my exp/drops go, and been running nightmare cows and now doing Hell Chaos Runs/Hell Travincal runs. I am not powerful enough to do hell cows solo yet, just need some guidance on the best places to farm and when to try some end gameish things to get better gear.

Currently my stats are: +enough str to wear stuff, rest in vitality.
My skills: Raise Skeleton (max), Raise Skeleton Archer (max), skeleton mastery (max), Skeletal Lich (max)
Amplify damage (+1), and now working on maxing Summon Mastery (currently +10).

Does this build make sense for what I'm doing or am I missing something?
Could someone point me out to some strategies or tips to help me on my way?
What should be my next destination in the game?

Thanks very much! I am having a blast. Merry Christmas!
