I wasn't following builds for sorcerer. Just going with the flow.
I mainly use chain lightning, on 28 level with max mana 119. After 4 strikes, I'm out of mana. Just recently, I started using crackling energy with mana restore upon pickup.
I feel like I could improve somewhere.
Any tips that doesn't involve looking at complete builds?
Question aside, does diablo have a tool for showing your current char?
Update:
Thank you for the tip! I'm looking after missing aspects and better gear with mana regeneration and cost reduction.
In the meantime, I switched to ice. Opening with Blizzard then Frozen Orb with Frost Bolt support. Occasionally Frost Nova and Ice Armor if the group is really aggressive.
