I was clearing mid thralls in Overgrowth and actually did do it really fast, the thralls only had time to break my shields before I had killed them - but before he died the last thrall shot out a grenade and… Dealt almost 3K dmg with it.
Has this happened to anyone else? An odd experience, definitely. I know they have a grenade attack they use against sentries but we were just at the mid thrall camp, why would they use it?
The death recap isn’t very accurate either so it doesn’t really explain what happened but I’ll add it here anyways. I’m not sure what that percentage is supposed to be though and I know it didn’t last that long, I took them out in one ULT.
