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

Actually played this as Lightning Arrow for the majority of the league. I saw another post on this subreddit using Heatshiver + Immortal Flesh and thought to myself wait, that's like 10x better than Voll's + random Stygian. Went from something like 100m LA + Artillery Ballista DPS to I think 140m, due to heatshiver. Interested in taking the build further, if anyone would like to take a look at my POB and point out any mistakes/gearing upgrades I can make. Kind of unsure how much the 50% inc effect of ailments mastery is helping me, for example.
