I definitely think that there should be a theme larger than just a particular hero (or group of heroes) for future monthly contests, people are always going to be working on items and sets so the contest doesn't really change anything about that. I think the themes should be based on less specific things like lore, hero…
Congrats to everyone who got some items in! This is my submission for the monthly contest, if you like it drop it a vote! Legacy of Avernus by Stuburrito
