Adding on to the suggestion because I think it’s cool, my idea would be something like :
The icons would look even more detailed with numbers but I think numberless is still kinda good but less friendly to newer players.
A - The icon when burn is applied to you, just a concept but it would look like a fully saturated bright icon
B - The icon when burn has ticked for 2-3 seconds leaving only half of the icon fully bright (I drew this in MS Paint I couldn’t use brightness overlays)
I don’t really know where icons like these would fit perfect so here’s a rough illustration on how they will look like in the UI. Might not be the perfect spot so maybe yall can suggest good spots on where to put it.
