I've been looking for a way to make the health bar switch to a completely different colour at a certain percentage. 20% in my case, and probably more than mine tbh. ;D
I've seen the options for full/half/empty in Colors > Health Bar, but those are far from optimal... and they blend as I recall.
What I'm looking for is a simple and complete switch at 20% (or lower), nothing gradual at all. Simply for the sake of very easily knowing when to expect a hammer of wrath, kill shot or execute... or when I can pull them off myself. ;D
Here's hoping it is possible!
