Erasing strike and void rifts bugged?

Erasing strike description: “… Enemies killed by by the hit are erased from existence, replaced by void rifts”.
What are void rifts? I tried googling, people say about some kind of spell that looks like purple circles. I see completely no effects after killing enemies. Is it bugged?

Anyone else?

Void rifts are purple AoEs, they’re easiest to see with Devouring Orb on kill (even an unspec’d DO). However because Erasing Strike is a massive bright purple AoE it’s harder to see the smaller darker purple AoE underneath it from the Void Rifts. It’s been mentioned before.
