Getting back into the mix.
So, I've been playing Diablo 3 for a while (5 hours), and I have kinda been mindlessly grinding, and I don't know metas/strategies, etc. I don't feel like redoing the campaign to figure out all the gimmicks to this game (like a tutorial), so I was hoping someone could guide me through adventure mode for all the IMPORTANT NPCS and things I really should care about. I quit Diablo 4 because it got boring, and D3 seems more entertaining right now.
I started to play Necromancer because Blood Spear feels REALLY fun to play with.
