Haven't done one of these in a while since I mostly skipped the 3.16 league of PoE, but the self-cast buff and new atlas passive tree of 3.17 was enough to wrench me back for awhile (lol).
Originally, I was planning to make this a Crackling Lance build, but Storm Burst performed so well from the moment I got it as an interim option at Level 12 that I just kept it and shifted my build to accomodate it. Probably for the best since the mana cost of CL is extremely high if you also want good DPS.

It has notes about various decisions taken.
Probably not of huge interest to this sub, but figured I'd share it anyway; maybe there are some interested in seeing if silly channelling stuff is viable, eh?
