You destroy the worldstone
Get back to the Hellforge to destroy both baal and Diablo’s soulstone like it was suppose to be when Blizzard north developed Lord of Destruction
When you destroy Diablo’s soulstone, you hear Aidan saying “I thought i could do it, thank you for finishing what i failed to do”, and then there’s an explosion that engulphs you and you are brought back to Tristram, the Diablo 1 Tristram
act 6 consists in a Diablo 1 remaster(Belzebub cut-content style) played through Diablo 2 resurrected
I feel that D1 would never be remastered so this is the closest it could get and it would be a great opportunity to not only make discover D2 to people who werent born to play it but also the origin of the game
Extra-Hypothetical section
You could have a new skill per class based on D1 skills called Legacy skills
- druid could get elemental(my favorite spell in all Diablo franchise)
- Necro could get stone curse
- Barb could get Blood boil (Performs a cry that boils the enemies blood making them explode on kill dealing damage to nearby enemies and you as well)
- Amazon could get Blood Star (Both jav and bow)
- Assassin could get Lightning wave (in line with shocked web)
- Sorc could get Apocalypse
- Paladin could get a buff to Holy bolt through Holy mastery ( X% of your Holy bolt damage affects non-undead enemies)
New items from the expansion could simply be those items that disappeared between D1 and D2
- The Butcher’s Cleaver
- Gotterdamerung
- Constricting Ring
- The Mangler
- The Grizzly
- Immolator
- Thinking Cap
