Awesome! I would like some variables too! Maybe you attack a boss with a bleed and this triggers additional minions. Im all for random and new encounters. Add Kittin invasion, end boss is a puzzle, like NPC. Only it's not game over if you fail, just add penalties and additonal challenges. We can use existing mechanics, just need to think outside the box to make it challenging again! Wish i had more ideas that were easier to implement.
