It’s still possible to reset Nightmare Dungeons solo in Patch 1.1.2, but the Group Reset no longer works!
Rob2628 showcases how to reset Nightmare Dungeons while playing solo.
- Kill all mobs inside your Nightmare Dungeon until you reach the final boss.
- Instead of killing the boss, leave the dungeon.
- Now, you need to do something else for 2.5 minutes, go back to town, salvage your loot, go over your items, or complete an outdoor event.
- After the time is up, you can head back to the Nightmare Dungeon and it will be reset.
