I have zero knowledge on newer league mechanics and a ton of info, still catching up on the leagues I missed

it would help if someone can let me know what's meta I guess basically, which item base do people use these special exalted orbs on?

Slamming for the influence mods.

Ex. Slamming hunter orb on good roll boots with open suffix and hope you get tailwind.

poedb is a great source but

explodey chests
culling strike gloves
tailwind boots

es/life% on belts (stygian vise)

oh i completely ignored the part where it adds a random mod

I was just thinking it changes the influence

Bleeding immunity on shields.
