Fans of Path of Exile, here's a precious article for you. This build for the Ice Spear Totem, also called the Gatling Gun Girl, costs a fortune and is only for the Scion character (Ascendant, Heiress class). These two facts make the task unsuitable for those in the Standard League, as the class can only be unlocked during Act 3.

Passive

In the skill tree, unlock some life nodes to get to the passive Constitution. Then follow the path of the three elemental resistances (fire, ice, and mouse) by opening the jewel slot and POE Orbs reaching for the passive Sentinel instead of melee damage. Then, following node Shaper, get life, strength and some life regeneration nodes. Follow up-to +10 Intelligence past the jewel slot (pick it up too), turning left before the circle with another slot. Continuing down for a few more nodes will bring you to the totem circle with Ancestral Bond. Take them all.

For your ascending skills, go to Path of the Templar until you reach Hierophant. Then choose Chieftain on Marauder's path.

Equipment

Depending on your level, you can use Tabula Rara with the +2 Level of Socketed Projectile Gems feature. For your weapon, you can use two Axiom Perpetuum and Buy POE Orbs any initial projectile gems. At level 20, get a Kikazaru ring. Arriving at 22, get a Coward’s Chains belt and at 24, the Karui Charge Jade amulet.

Your best weapon will be one with Added Cold Damage to Spells, Cast Speed ??, and improved Spell Damage. The belt should be a Stygian Vise with an extra jewel fit, resistances and somewhat Maximum Energy Shield and Maximum Life. Place a jewel that gives Maximum Life, Energy Shield or Added Cold Damage to Spells.

For your gloves, try getting one with boosts for Maximum HP, Energy Shield or resistors. If your dexterity is low, you should try to build something to improve it.
