Charms: At least 2-4 lightning charms are needed for this. Anni if you have it (obviously), mana, life, and resists.

Play tips: Charged strike is the biggest beatstick ever. Any large model monsters (Venom Lords, all act bosses, Minions of Destruction, etc.) will be hit by every bolt, meaning huge amounts of damage. With -enemy resists, you'll smash anything without lightning immune. Use valk and merc to aid with physical damage and soaking.

LF is great crowd control. Lightning Strike, when working properly, deals well with spread out monsters, while Power Strike deals extremely well with individual small model monsters.

Numbers to shoot for:
1.2k life
400+ mana
