It’s possible to skip a significant portion of Lower Blackrock Spire (LBRS) in WoW Classic by jumping off one of the platforms near the beginning of the dungeon. This is particularly useful when doing fast runs for the UBRS Key Quest: Seal of Ascension.
- After entering Blackrock Spire, go up the ramp on the right to enter Lower Blackrock Spire.
- Hop down and follow the normal path to the left.
- Once you enter the Hordemar City sub-zone, stop and immediately look to your right. There are a set of ledges that can be hopped down to the lowest level (right before the Spider Boss).
- For the last jump, try to land on the tent to take the least amount of fall damage. Be prepared for combat, as you will immediately pull aggro of the nearest group once you reach the bottom level.
