For those wishing to theorycraft spectral helix in POB, you can do a simple hack with the info currently available, a few simple edits to a couple of files.

​

Step 1) Make sure POB is not running. Find the lua files in C:\Users\[username]\AppData\Roaming\Path of Building Community\Data

Step 2) Use a text editor to open Gems.lua and add the following code to the skills array (line 5). ** make sure to press enter first so you are pasting onto a blank line **

["Metadata/Items/Gems/SkillGemSpectralHelix"] = {name = "Spectral Helix",grantedEffectId = "SpectralHelix", tags = {dexterity = true, active_skill = true, attack = true, projectile = true,}, tagString = "Attack, Projectile", reqStr = 68, reqDex = 98, reqInt = 0, defaultLevel = 20,},

​

Step 2) Use a text editor to open Skills/act_dex.lua and add the following code to the skills array (line 9). ** make sure to press enter first so you are pasting onto a blank line **

skills["SpectralHelix"] = {

	name = "Spectral Helix",

	color = 2,

	description = "Throws a spectral copy of your melee weapon. It spings around while flying in a large spiral, damaging enemies in its path, and bouncing if it collides with walls.",

	skillTypes = { [SkillType.Attack] = true, [SkillType.ProjectileAttack] = true, [SkillType.Projectile] = true, },

	weaponTypes = {

		["One Handed Mace"] = true,

		["Thrusting One Handed Sword"] = true,

** NOTE make sure there is a line break for the next skill (AnimateWeapon)

Step 4) Save the files and open POB!

​

This only has the data for a level 20 gem with 20% quality for levels 1-40 of the gem. If you do not have coding experience, I recommend making a backup copy of any files that you edit.

This will cause POB to show "Update Ready". Clicking this button will revert your changes. Typos can break the code and cause an error.After doing this you can try an example build:

Thanks to /u/c97hristian

for the build on this thread:

The only change I made was setting the skill to Spectral Helix
