I'm going with DMO set with frozen orb in season 16 and it's fun so I would improve

My build:

https://www.d3planner.com/906725767

The build is from Rhykker and he suggest strongarm bracers but dunno why

What proc in this case the strongarm? (maybe the wave of force from tele?)

I use exactly the same build except I'm wearing witching hour now and use shame of delsere in the cube, should I use the strongarms instead?

any suggestions are welcomed
