Overhead icon reference anywhere?

Is there a complete reference for the icons you see over the head of yourself and foes?

I keep seeing a blue symbol like alpha rotated ccw 90 and have no idea what it means.

There are others I don’t know as well.

Edit: a reference for other visual effects would also be helpful like the rumor devotion seems to produce a spiral of falling transparent blue balls around the victim? A rising cloud of red skulls from something else?
