The items brought back from the event adventure are pretty chintzy this time. I can usually get the hardest to obtain item (in this case it would be the troll essence) about every other time. However, this time I’ve gone on the adventure 3 times and only brought back the easiest items to obtain. So not really worth it so far, but I’ll try 1 more time to see if I can get the troll essence.
Update: 4th time did return troll essence. Not as good a return as other event adventures, but maybe the percentage will get better.
