Naturally, it’s easiest to solo this as a rogue due to vanish, lockpicking, and stealth.

If you want to solo this as a non-rogue, you’ll need the following:

1. Shadowforge Key (for opening gates)
2. Invisibility Potions (for getting past mobs without aggro)
3. Patience (self-explanatory)

Attunement Quest

Pick up the Molten Core attunement quest, Attunement to the Core, from Lothos Riftwaker, located at the base of the main chasm in Blackrock Mountain outside of the entrance to Blackrock Depths.

Solo Guide (Video)

As a non-rogue, you’ll want to pop Invisibility Potions in some of the more narrow spaces.

Note: It’s possible to lava jump under the final bridge (~3:30) instead of running through the 3-pack. This is recommended for non-rogues. As a rogue, it doesn’t really matter as long as your vanish is off cooldown.
