[PoE 3.5] CoC Dark Pact Occultist - Lackluster Build Test

Path of Building: https://pastebin.com/gTAS36cS Build Guide: https://www.pathofexile.com/forum/view-thread/2319331

Had the build concept weeks ago with charged dash on crit for some hilarious Tokyo drift actions and speed in map clear. The initial spell planned to use was Ice Nova, but everyone is playing it so I'm gonna try something different instead. I have never play Occultist, charged dash, dark pact and cast on crit before so i started to plan the build accordingly and in the end it turns out pretty well after some theory-crafting and reading build guides that turns out it can work. For Mapping, Both Charged Dash and Cyclone works fine. Blade Flurry on the onther hand is much better single target skill for easier positioning imo. The passive skill tree and build concept is very similar to most cast on crit builds. It can be pathed into ranger area for dodge + spell dodge as extra defensive layers. However, I tried to be slightly different from the build guides and focused on curses instead.

The effective DPS against Shaper/Guardians are about 400-500k on thoery. In most ideal single target setup with at least 3 skeletons alive, then dark pact will chain twice. That means with 27k damage per cast on skeleton, it will 3x 27k = 81k per crit. On average of 5 attacks triggered per second, it will be 5x 81k = 405k DPS. However, I might be wrong on the DPS calculation regarding this skill as this is my first time playing this build. Please correct me if I'm wrong.

This build can run most map mods, but there are some of them I tried to avoid as soon as I realized they are very annoying and risky to run:

1. 60% less life recovery rate, unless u keep summoning skeletons, else the 6% cost of life from dark pact on every hit is kinda hard to sustain even with the leech from warlord mark. (except if u are using Cherrubim's Maleficence or other sources to boost your leech rate)
2. Less curse effect, simply lessen my crit chance since I'm using assasisin's mark.
3. Cannot regen can be annoying if using cyclone, because cyclone has 3 times higher mana cost than charged dash/blade flurry. Especially when runs out of mana by accident, cyclone doesn't use default attacks like other melee skill does to gain back your mana.

Some possible improvements, replacement of skill or dps boost for better clearing/single target setup:

1. Wither Totem
2. Aspect of the Spider
3. Despair curse
4. Vaal blight
5. Vaal RF

Some of my gears crafting cost breakdown:

1. Claw = 6ex
2. Chest Piece with +1 Curse = 3ex
3. Warlord's Mark Elder Ring = 2ex
