Diablo developers offer a deep dive into how the climactic boss encounter for the Lord of Hatred expansion came to be in the latest video.
Highlights
For anyone who still hasn’t played through the Lord of Hatred campaign, the highlights contain spoilers.
- The team has been pushing the mechanics and gameplay for the genre and their titles for the Mephisto fight.
- The goal was to pay off the in real-time three-year-long-story players have experienced with Mephisto.
- For the player character it is the most significant thing that’s happened to them, possibly ever.
- Phase 0 with Akarat came about a make-a-wish, a nice-to-have because the devs were stoked after the cinematic at the end of the first expansion. That was a promise between the devs and the players that you’re going to fight not just Mephisto but Akarat wielding that sword.
- In terms of balancing the pinnacle boss, the Uber fight they wanted a phase where they could be a little meaner to the players.
- Phases 1 & 2 are mean, but they were designed to have very deliberate and slow attacks that the more you play it the more you realize that you can dodge almost all of them.
- The Akarat phase gave Blizzard the opportunity to throw a lot of unfair attacks at the player to filter them out.
- This allowed them to have no checkpoints for the fight, because the front-loaded a lot of the pinnacle difficulty, so if you are going to fail, you will do so early.
- Having that tension, that quiet before Mephisto is such a fun thing to play with as a writer to then really just have it explode when he falls into the Pools.
- Ferrofluid has a lot of different forms in the game.
- Phase 2 is really big and loud so they had to carve out various frequencies for different attacks. When the arm blades come out, you get much more of a sharper sword swing, because that cuts through the mix more versus when Mephisto does the giant ground slams that’s got your big, bassy explosion and that takes u pa lot of room dynamically.
- There’s a bone crunch sound when his rib cage opens, and more.
