PoE Blast Rain, Cold, Duration builds

POB for the character being showcased: ~~POB for a general guide including leveling:~~ ~~ Updated guide with personal findings: Leveling was done using Rain of Arrows + Artillery Ballista. You can start using manaforge as early as level 8, but I wouldn't rely on it for damage until mana problems are solved with a Thief's Torment (minimum level 30). Early lifetap is NOT recommended. You can still use Frenzy
