On the D20 shrine, I received the "Unsteady" buff/debuff. I have not noticed a change in my accuracy, however I did notice a change in my reload speed. At least on my marine sidearm I can reload my weapon within one dodge roll with a few milliseconds to spare. Before it takes a little over one dodge roll to reload.
I don't know if it's relevant, but I was holding the marine sidearm when I rolled the bones with the shrine.
Hope this helps. Maybe other players can determine the Unsteady buff/debuff on this same discussion?
I got a screenshot of the Dice shrine exploding. Enjoy.
