PoE Hardcore, League Starter, Cold, Duration builds

PoB: Pretty late in the league so this probably won't get much traction, but I wanted to post this anyways as this is one of the most fun builds I've ever played. I won't claim there's anything super unique here as the core is just a pretty bog-standard power charge stacker, but I am surprised at how relatively underused CSoP is cause this thing hits like a truck (albeit a smaller truck than Penance Brand I guess lol). Pros and cons first and then I'll go into a little more detail about some interesting aspects. Pros \- Insane

Leveling Tips Act 1 - 5 Rush Elemental Overload on skill tree, if needed pick up Health Mana nodes on right side of witch starter area, i go for life on top right first then branch left to templar area. Buy Minion damage / Infernal Legion support in Act1. Socket in Summon Skitterbots in Act 2. Also optional to level Spiritual Aid during leveling to boost both your and skitter DPS then respec out of it later. On lvl 28 equip 4L Vortex + Deadly Ailments + Cold to Fire + Ignite Prolif
