Guild Wars 2

So we were doing this chain of events about defeating monsters in an arena, that ended in an event called “Defeat Vollym, champion of the battle pit”

When vollym reached half hp, he gained a buff called “Determined”, wich makes him immune to all damage.

The boon had 10 minutes until expiration, and the event had only 3 more minutes until it would end, so obviously we couldn’t defeat him.

I’m not sure if this boon was dispellable, but as mt guardian has no boon dispelling abilities that I know off, I could not find out.

It’s supposed to go away when you kill all of his wolves. However, I’ve seen it get stuck on at least 2 occasions.
