Strength Stacking Power Siphon/Kinetic Blast Poison Assassin

Hello everyone! First time sharing a build showcase of mine here, so any feedback would be great.

Intro
While not completely original, I was inspired to play this build this league since I hadn't played KB in awhile and wanted to take my Celestial MTX for both Power Siphon and Kinetic Blast out for a spin. This was my league start build and I've just played this one up until now. At the beginning, I wasn't sure if I wanted to go Int stacking or Str stacking, but I decided to do Str stack since it seemed like it had a lower cost of entry. Most of the guidance for the tree came from looking at old builds from Heist league when the strength stack variant of poison assassin wander became popular due to Replica Alberon's Warpath. Skimmed a couple of the forum guides, looked at Mathil's build, plugged a bunch of POBs, then started building my own from there and here we are! I wanted to share since this is my first character to 99 which I achieved without exp carry services and through constant map grinding. While I did avoid Sirus because I play him like a blindfolded clown, I took on all Conquerors still and every Trialmaster encountered for the chance at the sweet rich Hateforge. You win some, you lose some, and those deaths really set you back.

If I end up doing deathless A9 Sirus or Maven, I'll upload those recordings as well. Uber Elder is also something I'll upload once I get another set.

Gear Details and Current Investment (without Headhunter): ~100ex
Helmet (~40ex)
Maven orb gambling can really jack up the price of something. Getting the elevated crit chance per 10 strength took 5 attempts which burnt through the funds from the first Doctor card I ever found (which also happened post purchasing Headhunter). From there instead of taking the safe route and setting myself up to craft increased duration of ailments when focused as my 3rd suffix, I gambled an Aisling slam and got hybrid Str/Dex instead. Even Str/Int would have been better... this is something I would like to start over. I may farm lab and if I get the General's Cry enchant, I can at least switch the current crafted mod to the melee range one and probably flip this for a decent return.

Wand (~17ex)
My current wand cost me 17ex but my old one cost me about 2.5ex in fossils/resonators which I used until a few days ago, so it's just a minmax luxury piece. I didn't want to dump more for better crit rolls because protecting prefixes with an open prefix was 4ex a reroll and I'd rather spend that on a legacy elder poison mod. I only needed T3 crit chance to reach crit cap but I settled for T5.

Chest (~20ex)
Chest cost roughly 15ex since I linked it myself with the bench and farmed my own Aisling. Don't feel the Crusader explode mod is worth it, and I only got it because I thought the chance to explode would stack with Unspeakable Gifts but I believe I am mistaken and so I want to recraft for something else.

Other High Value Pieces
Watcher's Eye (~13ex) and Bottled Faith (~14ex) are also luxury items, although Bottled Faith is pretty nice for the crit boost. If you want a more detailed price or crafting breakdown, or scaling of what gear I used before in each slot, just let me know. I crafted a good chunk of my gear to some extent with some different methods, my first time really diving into it too so I can probably share some tips if you have questions.

Ending Thoughts
Very fun build, I believe I missed the peak of it's power in Heist league as it's seen a bunch of nerfs since then: the scaling of chaos damage added per 80 strength instead of per 50, nerfs to the Assassin poison ascendancy nodes (and even other nodes too I think), losing the old Crusader explode mod, and even into this league losing the old Elder poison mod on weapons. Still did great for me this league as I did farm up to get Headhunter, do a good chunk of crafting and interact with those more expensive systems, finish my 36 challenges and hit my highest level character. There is still more work to be done, and my biggest upcoming changes may be crafting a new chest with maybe some elevated mods and swapping Crusader explode maybe for Redeemer frenzy on hit or Hunter attack crit chance. Gotta say though, I'll probably get a 5-way legion service to go to 100. Thanks for checking out the writeup!
