Guild Wars 2

This happened in Lychcroft Mere area. I wasn’t in combat at the time. According to the log I got hit by some unknown force two times in rapid succession:

“You were hit for 1457 damage by Unknown using Explode.”
“You were hit for 1356 damage by Unknown using Explode.”

This is a level 23 area, so this amount of damage got me downed instantly. I believe this might have been a bug, so I took a screenshot.

Unknown usually signifies a creature that has just come out of stealth and has not properly rendered and had hit you. Though I am not really sure what low leveled enemy that can stealth and explode.

Sounds like it might have been a Risen Plague Bearer or whatever they’re called. If it’s the place I’m thinking of, you could easily have had 2 spawn near you, and not render properly before they blew themselves up.
