Like many players, I have found myself frequently asking questions like: "does this item work in the desert?"

Although many buff items list the areas where they are effective, these tooltips are often inconsistent and sometimes completely missing. For example, the tooltip on Fortune Scroll says "Increases the drop rate of Spoils of Battle and Spoils of Hadum by 5% for 3 hours." This implies that it works in Elion and Hadum, but it's not clear whether it works in Nightmare or Field of Valor, etc. In a similar vein, the tooltip for Special Chicken Soup also does not clarify which areas it works in.

I suggest that the developers should add simple icons to each buff item to clarify where it is effective. You could simply take the assets that already exist (icons for each zone, i.e. Elion, Hadum, Desert, Valor, Nightmare, etc.) and display them in the same style that classes are displayed on weapons. This would make it quick and easy to determine which areas a buff is effective in.

Here's a mockup I made that shows my idea (the icons in the bottom right):
