I have pulled out the cost of my rares from Client.txt and I thought this could be interesting maybe? Usually build guides are pretty vague on costs. I followed mostly this comment in pivoting to CI, my version is https://pobb.in/jmCThtdHmd5N forget the zombies they are not required just a nicety, I could squeeze them in because I got insanely lucky when I double corrupted my shield. The price for that shield is most definitely not included in the costs below.

1. Demon Braid Coral Amulet 1.8 exalted but this is misleading because I Leo slammed it since I bought it and got 14% all res. Looking at trade, it's worth about 3ex now.
2. Brimstone Whorl Unset Ring 150 chaos.
3. Corpse Loop Unset Ring 60 chaos.
4. Behemoth Goad Convoking Wand 3 exalted.
5. Foul Leer Ghastly Eye 100 chaos.
6. Fate Visage Hubris Circlet 9 exalted.
7. Maelström Strap Stygian Vise 50 chaos.
8. Onslaught Sole Conjurer Boots 1 exalted.
9. Gloom Touch Fingerless Silk Gloves I bought it for 4 exalted but I only kept the two implicits, I slammed a few deafening sorrow essences on it until T1 resistance (craftofexile says this takes about 0.5ex), convert to cold, benchcraft %ES, lucky reroll once, and paid 50c a lab runner for the enchant. Less than 5ex still.
10. Plague Stone Large Cluster 5 exalted (gosh, that was hard to find in the log because it was in Russian)
11. Hypnotic Stone Medium Cluster Jewel 1.9 exalted

So 1.8+3+9+1+5+5+1.9=26.7ex, 150+60+100+50=360c

Uniques from trade, they are nothing special (and I need to divine my Fortress Covenant, I know):

1. Fleshcrafter 6L 2ex
2. Aegis Aurora 1ex
3. Fortress Covenant 20c
4. Quickening Covenant 5c
5. Melding Of The Flesh 3.8ex
6. Dead Reckoning 5c

The rings and the belt are slammed with defense catalysts. Especially worth it for the belt. That's another 60c. I used <20 lesser eldritch Ember/Ichor each on the boots to get these. Ah yes, I also needed a lucky prefix roll for the boots because they were only 25% MS when I bought them.

Overall we are looking at 33.5ex + ~2.2ex in chaos so call it 36ex.

Then you need gems, by now they are not horribly expensive, even Awakened Minion Damage level 5 is <1ex. Overall, this should be about 2-3ex.

The flasks I rolled myself, no idea about how much they are worth but they are truly nothing special.

Ps. Aegis corrupt is 14ex for Discipline, 19ex for this double corrupt. It's half again the cost of the entire build.

Pps.: I made an upgrade, got 2% increased reservation efficiency on Quickening Covenant (2ex, ouch) and Dead Reckoning (just 15c) both which allowed me to drop Righteous Decree and the small mana skill leading to it. When testing make sure casting skeletons twice casts Bone Offering, it's a lot of mana with the trigger. I used the two skill points for the small minion damage node next to Righteous Army and for the 5% attributes mastery (Utmost Intellect). Now, this means I almost have enough strength (152 vs 155) without the str+int benchcraft on the ring. We could get 3 strength by replacing either the small or the medium cluster jewel with one that grants it. This makes various upgrades easier/cheaper. More to come :)
