It’s the event where you find an injured adventurer and two of their companions. They want you to protect them from the waves of enemies but they get melted within the first 10 seconds or so no matter how much I clear the waves. I’m lvl 56 playing T3 and I’m using a melee rogue with really good AoE damage.
Is there a trick to luring the enemies away from the survivors and towards me?
The trick is… you don’t get the mastery.
I found another I found in a cellar that seemed impossible - there’s a guy trying to absorb some creatures or something (hey, I wasn’t paying attention!), but they only seem to spawn one after every wave, and the guy has to do some long animation thing after you get the creature to 20% health or so. I only managed to get 2 of 5 done by the time the timer ran out. Maybe it’ll be easier if I ever see this event again at a higher level, but I’ve only seen it once so far since release.
