PoE Cast On Critical Strike, Cold, Duration builds

PoB: This build uses Kinetic Blast to Cast on Crit Dark Pact + Chain. I threw this together since I got a minion life relic and always collect CoC poison gear for fun to try stuff. The idea is that KB might sometimes look like a real CoC skill if you chain it off a Tornado. We create Tornadoes and skeletons using Poet's Pen. This build slapped way harder than I expected when I equipped it, so I thought I'd share. I'm wearing literal random gear. The core of the build can be considered poet's pen + watcher's eye + rings.

Looking for input on the following build. I filled in a passive tree and added the mandatory items I know of. I'm going for a Low Life Occultist that uses cyclone+CoC+cold dot. From how I picture this... 1) cyclone crits and causes cold snap to proc. cold snap generates frenzy charges. (inner conviction on passive converts frenzy to power charges which boost all spell dmg). 2) I hand cast vortex which is the primary damaging spell in addition to cyclone. 3) Cospri's Malice auto casts ice spear, frost bomb and vaal ice nova. 4) I've taken 2 curses - frostbite and elemental weakness whic
