I finally beat Piety in normal, first time in hardcore making it that far =/ A lot of near dead moment, I felt like I am either pretty under gear or screwed up my build big time.
I am trying to go for high block tempest shield + lightning trap focusing on lightning damage. It seems like I ran out of mana after 7 or 8 traps (without spamming flask), and even faster if I link it with +lightning damage support gem (only have it linked with lightning penetration atm). I don't run out of mana farming, since the mob refill my flask pretty quick, but it becoming a problem when I am trying to fight a boss.
I have like 200 armor, ~35% block chance, 700 health, 400 ES, resist 75% fire, 40% ice and lightning. 650 mana, 30% reserved by tempest shield.
My build, trying to get all the shield block nodes that I can, along with the trap passive (10% penetration, 6s indestructible, +1 trap)
Any help will be great.
