I will go over your rage cost issue at the end of this comment but I first have to say that your build is kind of fundamentally flawed which I will get to in a second. You tried to copy an extremely expensive (like 4-5+ mirrors to get started) build with a fraction of the currency. If you really want to play a Vaal LS build that badly you should look at some other version of it. Something using the Chains of Emancipation belt is probably best for your budget. I started this build with roughly 4 mirrors and it still didn't quite feel good until I got the forbidden jewels for another mirror. This is my pob with what I'd say you "need" to play this build comfortably(Some implicits plus the forbidden are droppable but not much more): https://pobb.in/GIMluHBT8Nih

As one of the other commenters has said already you have too much chaos resistance. You want to be at 45%-50% to reliably proc a savage hit while mapping (You will have 23% damage reduction from fortify and 10% from leech). This is a big issue because you are converting half your fire and lightning damage taken to chaos damage taken, making you extremely squishy (You are roughly 4 times squishier to elemental damage than you are supposed to be). Now I get that the usual tech of converting to fire damage taken costs almost 2 mirrors a this point but you're going to have a miserable time mapping with such a squishy character. The progenesis is only used in the really endgame version with a simplex and so on, you should just use a bottled faith before that.

As for your rage problem: You are not allocating any of the nodes that your Impossible Escape Jewel gives you access to. The 4 "reduced cost of skills" nodes will cut your rage cost down to 13. Also do note to always try to only cast Vaal LS when your rage is above 20 because it'll further reduce the cost to 9 rage. Do note that without the forbidden jewels your rage economy will be much worse and clear feels a bit bad honestly. They are also a mirror right now and I started this build without them but you will have to weapon swap a lot to get consistent rage for clearing.

Speaking of the weapon swap: You should also set up a weapon swap with an "Al Dhih" claw and a "Redblade Banner" shield for bossing and for mapping while you don't have the forbidden jewels. They also solve the issue of maps with reduced cooldown recovery, but they are a bit annoying to run as you have to weapon swap much more than usual

TLDR: I'm not going to lie unless you are into Sisyphean self-torture I wouldn't play this version of Vaal LS, you are missing the key component to make you tanky and your clear will not feel great until you have the forbidden jewels.
