This is my first post on this forum, so please go easy on me if you don't like my idea. But tell me if they're bad though..
So, I'm hoping for ways to equip items to the Heroes. Namely Barbarian King & Archer Queen.
We could be given new quest challenges that when cleared, give us equipments, for example, Swords, Bows etc. And they can be of different qualities increasing a different quality of the King & Queen.
For example, once equipped with a really Heavy Sword, Barbarian King's strike power goes really up but speed slows down. We could swap that with a Light Sword to Lower the strike power a bit but Increase the speed a lot.
Same scenario with Archer Queen, stronger arrows, or faster arrows..
