| 6 | ![]() Grab the Bruce Bomb from the console and throw it at the barrier to destroy it. |

| # | Walkthrough |
|---|---|
| 1 | Grab a Bruce Bomb nearby and throw it at the barrier to the south. |

Quickly grapple to one of the stone platforms outside the arena to avoid the blast. |
| 10 | ![]() After defeating Vile Lictor, take his bolt to trigger another cutscene. |
| 11 | Return to Belton's Bore and talk to Defiant Calder to complete the mission. |
If you Fast Travel out of Vile Lictor's fortress during the mission, you may be wondering how to get back inside.
To re-enter Vile Lictor's fortress, return to Substation Canonary or the power substation and reach the chamber where the energy spike was. Stand where you huddled with Bruce to be teleported back to the cave in The Low Leys. Enter the Phase rifts again, and you'll find yourself back at the gates of Vile Lictor's fortress.
