I'm seeing a strange icon appear over enemies on a random (fairly rare) basis. The icon I'm talking about is shown on the left side of the screenshot below:
In this screenshot, you can see it appear over two stone pillars. When it appears over normal enemies, they appear to run away from me. None of my gear currently seems to have a unique effect (it's all pretty standard stuff), so what am I missing? Any ideas as to what this icon means?
Update: So I was able to recreate the icon on the practice dummy in town, but there's no associated effect icon above the enemy health bar! Here's yet another screenshot:
Note that the only two effect icons that show up are, in this instance, burning and my weapon's special effect (which happens to be silence, if I remember correctly). I've seen these icons outside of seeing the large yellow one above the enemy, so I don't think they are related. The mystery deepens...
