PoE 3.21 Crucible, 3.24 Necropolis League Starter, Cold, Duration builds

Hello fellow BoneZoner, planning my league starter for the next league. I only play SSF and been a long time bonezone enjoyer. excited about a new twist with trauma support ive thrown together a quick pob: glad for any feedback and optimization. gear is pretty basic and realistic for my playtime in the early progress in the following league

TL;DR| Pob link here: ---|--- Quick Explanation | A level 24 creeping frost skill gem is used to simulate the expected damage of a level 20 FB skill gem (based on comparisons with Searing Bond.) On Shako, I've added a 410% more damage over time modifier to simulate the level 30 version of the skill (based on searing bond's scaling.) There is a non Shako version under the Default tab, which is just a down-grade in practically every regard. Both use Supreme Ostentation, because league reasons. Build is fully built, but not optimized. There is almost certainly better

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

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
