LTendrils-CwC-LWarp - my very first build (since level 1) in 2000+ hours of PoE! I'd appreciate recommendations for cost-efficient gear and/or passive tree optimization

https://pobb.in/2RIhYDT_zqL- - PoB (how does one adds Arcane Surge btw?)

League started it and started running CwC setup in a 4-link as soon as could get it on 40+ level, almost never went back from it except for 1-time exarch/eater/invitations fights where I put more proper supports and played "boring" (fully) stationary way. When my DPS was lacking more, I sometimes swapped one gem (LWarp) to Innervate vs Liches but that's it, should probably still do it to save some time.

Anyway, the idea was born from me getting to 100 for the first time last league on Incinerate-CwC-Bodyswap Elementalist: https://poe.ninja/challenge/builds/char/MrCinos/Emma_Milfstein

that I retrofitted into similar kind of playstyle from level 80 (followed regular Incinerate build before that), I just wanted to do lighting-themed version.

When it comes to the equipment

The most expensive items that I got are - Awakened CwC gem (3.5 div), Aegis (2.5 div) and Watcher's Eye (2 div). Weapon, rings, amulet (excluding oils), belt, gloves, helm - all cost me less <80c on Trade. Although I do feel like I got a particularly good deal with the weapon. Aegis changed everything, haven't died for the past 200% exp.

Either way I'm pretty broke all the time and feel like I'm getting much, much less currency than last league so looking towards 4-5 div items at most this time as a goal if you've any suggestions. I should probably start from vaaling LT to 21lvl and getting quality on all the support gems first, but other than that not sure what to focus on first.
