Guild Wars 2

Hi,
while I was fighting a Guardian in a 1v1 in WvW, along came an upscaled necro from my own server who also joined in. Thing is I was taking damage from Torment.
100% was an enemy Guardian and a friendly necro.
Maybe the guardian has torment even though I checked gw2 wiki.
No other players were nearby.

Many thanks
