PoE Rumi's Concoction, Trap builds

Most poison seismic trap builds use Saboteur for trap advantages. Has anyone tried Occultist for the Chaos perks? I put together a quick PoB and it appears competitive with Saboteur. This was done really fast, so open to any feedback or suggestions. Everything in the PoB is current equipment on my Sab build with very minor tweaks. Is it worth rolling into this build? Obviously needs some improvements such as spell suppression. Any recommendations? Thank you!

Here is my POB for my league trapper i have a little more room to squeeze but not much more in the direction ive gone with seismic trap. Its insanely tanky, easily one of the tankiest characters ive played in the past 9yrs . Has plenty of damage and has beaten all rolled invites, simu upto wave 30 but sometimes its iffy. Its fun to play imo, very strong and reliable damage. Would appreciate any commentary, you can drop determination for pride and get around 2 mil dps. Its in the setups to fiddle around with, you can also do some jiggling with precision and purit

POB: Due to passive tree changes this is just a rough outline of notables and gear without factoring in Mastery for the most part. Reservations assume that Faith and Steel counts for Energy Shield Mastery (for 25% Discipline Efficiency) otherwise drop Tempest Shield or spend a few points for Insightfulness/Unnatural Calm. Open to ideas or suggestions for refinement. Never played spectral helix so unsure what sort
