Impale Blade Trap Sab with Enfeeble Blind Dread

Before it gets voided, just wanted some feedback on a build I'm currently running on Endless Heist

POB https://pastebin.com/60xwTu3u

Only level 40 so far so it's not a full build

So I started out wanting to go Poison Seismic Traps, but on the way wanted to try Impale Seismic Traps, then realised I couldn't really go Impale Seismic and went for Impale Blade Traps.

I think there's some defensive and offensive synergy between Blind, Lower Accuracy from Dread Banner and the reduced damage and accuracy from Enfeeble and Sabo Blind.

So when I have enemies blind and enfeebled, they should do ~30-45% less for trash and 25%-30% less damage and I can shove an immortal call on top of that.

Main issues I'm seeing are that ranged spells are going to be a problem unless I can get decent spell supression and phys may be a problem, especially at range. I don't know if Impale is actually doing much for my traps. Ultimately, I think it might be better to shift to Defiance, Determination and Grace with Enfeeble if I can fit it in.

I also suspect a regular Seismic trapper would eclipse the damage anyway,

Any thoughts? I think it's an interesting idea but I don't know if it works
