Best solo or grouped spots for necro 50+?

[alreadyhome]

Hello there all, I was wondering if there was a decent place to get a good % of experience per kill for Necromancers solo in Kunark? I have heard that Charasis is really good experience but I am not sure. Does Charasis require a key currently? (And is the quest doable by non-Iksar necros?). Finally, is there a decent place to get exp groups 50+ right now? I apologize for being so uninformed but I am just returning to the P1999 community after taking a break.
