I have so far submitted two bug tickets. My first was that flame blade with the druid uses the strength modifier for attack rolls. Upon further investigation I realized this was just a bug with the Inventory UI and during combat it in fact uses my wisdom modifier.

The second bug I submitted was with the shadow blade from the ring and the shadow blade passive from knife of the mountain king not applying advantage on obscured targets. Since advantage rolls are not shown in the combat log do you think these items could be working, but just not correctly displaying your chances to hit? If anyone knows a good way to test this let me know, as if it truly is working that would be very good to know.
