@Alicat, I understand your frustration but the trials arenāt certain colors/elements only. They are classes. Trials of Fortitude are Clerics and Druids which, unfortunately, are Healer heavy.
I myself used Rigard, Gade, Melendor, Caedmon and Boril. Boril really shines in this event as the bosses commit suicide on his repost, if you time it right. Caedmon also dispels Boss Borilās repost.
Now Iāve been playing for awhile so my heroes are maxed but due to the lack of heavy hitters I find Fortitude one of my least favorite Trials.
That said, itās not for everyone. Some can only do the 1st level, some only the 1st two levels. You need to max those class heroes to be ready for these mini events. It took me awhile before I even had enough heroes to have a full team!! If you expect to be able to complete every event without putting in the time and effort to max heroes, you are definitely going to be disappointed.
Each Trials has 2 classes you can use, of any color/element you want. Certainly some elements are better in some trials but we use what we have right? Thatās the challenge. So fight on and work to make your roster deeper so you have a number of heroes to choose from. It becomes easier as you progress in this game. Itās a marathon, not a sprint.
Good Luck on your next Trials Challenge!! I hope you are prepared and victorious!!
