Hello, all. I was going through the forum and saw some interesting challenge ideas just for fun and personal fulfillment, such as the 3 hero challenge and the one man/woman army challenge.
In the spirit of always pushing ourselves, may I propose another challenge:
Defeating Ursena with just dark heroes.
You may choose normal or hard, depends on your roster and skill. Of course, if you can complete the challenge on hard, that would be super impressive!
Let me know what you think!
