The controller feedback thread is closed, so opening this one here.

It would be rather cool if the lightbar on the Dualsense & Dualsense Edge controllers had some use in game.
Off the top of my head:

Changed to the color of the order of the emissary you're representing.
Souls - Purple
Gold - Yellow
Reapers - Red
Merchants - Blue
Athenas - Ghostly Green

Miscellaneous ones:
Pulse when a fish bites, solid when you can real in
Pulse on hitting a chest while digging

I don't believe any of this would be game breaking since there are sounds or visual queues in the game already and just provide a small cool effect to the Dualsense and edge controllers.

Side Note: There is no Playstation option in tags, so my apologies for the tags being odd on this post.
