I do like the idea of busting down avernus doom slayer style to demand a fix to karlachs heart. I'd hope to see something more akin to a survival type mission where damon(or some other skilled smith) works to upgrade/ replace her heart while the player has to keep devils and other avernus natives away. It would really keep avernus as a place that's terrible and basically a death sentence for any non devil but you can last long enough for the operation. As long as I'm given a fix I'm more than happy tbh. Uppercity is way more likely in my opinion to get adapted I'd just like to hear some kind of official word from larian.
