There are some valuable rewards to collect by opening the Brighthoof Secret Catacombs in Tiny Tina's Wonderlands, including a Doom Easter Egg weapon, but there are two side quests that must be completed to open the gate. The Secret Catacombs are located through the gate near the Wibblesern Well in Brighthoof. To open the gate, players will need to complete the "Lyre and Brimstone" and "Inner Daemons" side quests in Tiny Tina's Wonderlands.
The Secret Catacombs gate will be opened during the "Inner Daemons" side quest, but "Lyre and Brimstone" needs to be completed first to unlock it. The first side quest has players helping with a Battle of the Bands competition in the forest, and the second mission involves opening the gate by performing sins around the city. The recommended level to start the "Lyre and Brimstone" side quest is 15, but lower level players in Tiny Tina's Wonderlands can still complete the mission in multiplayer.
Completing "Lyre and Brimstone" will earn players $9,195 and 5,688 experience as well as the Metal Lute of Myth, a rare melee weapon. Only 565 experience points will be earned for completing the "Inner Daemons" side quest, but players will earn $10,299 and unlock a weapon that directly references a Doom gun. The Heckwader of the Hurricane is a rare SMG that deals fire damage, and it has 15% increased reload speed and 21% increased fire rate. Completing both side quests will earn players a decent amount of money and two new weapons, but each mission has several steps to get through.
- Step One - Lyre and Brimstone: Collect Evil Tree Branches
- Step Two - Lyre and Brimstone: Protect Talons of Boneflesh
- Step Three - Lyre and Brimstone: Collect Ingredients for Plaguerat Apocalypse
- Step Four - Lyre and Brimstone: Defeat Talons of Boneflesh
- Step Five - Inner Daemons: Choose Three Sins
- Step Six - Inner Daemons: Open the Gate & Defeat Leiara
Tiny Tina's Wonderlands: Lyre and Brimstone - Collect Evil Tree Branches
The "Lyre and Brimstone" side quest can be picked up from the Bounty Board or started from the quest location in Tiny Tina's Wonderlands's The Horns area of Weepwild Darkness. After speaking to Sinistrella, players will receive the first objective, which is to collect branches from an evil tree in Terra Sanguina to help Talons of Boneflesh become more metal. The tree in question will be marked on the map, but it's directly north of Sinistrella. The tree will be surrounded by Skeleton Mages that need to be taken out before the branches can be broken off. Three branches need to be collected using a melee weapon, then players can return to Sinstrella for the next part of the quest.
Tiny Tina's Wonderlands: Lyre and Brimstone - Protect Talons of Boneflesh
As a reward for delivering the branches, Talons of Boneflesh will play a song. However, the music attracts enemies, so players will need to defend the band and turn off the three speakers. There's a right, left, and central speaker in close proximity to the band, and their locations in Tiny Tina's Wonderlands will be marked on the minimap. Players will need to run to the speakers quickly to shut them off before the band is attacked, then run back to the stage to eliminate all of the enemies in the area. Even after the speakers are turned off, some enemies may spawn in. Once the area is cleared, the band will stop playing and the next step in the quest can be completed.
Tiny Tina's Wonderlands: Lyre and Brimstone - Collect Ingredients for Plaguerat Apocalypse
Straight across from the Talons of Boneflesh stage, there's another band that needs help getting ready to play. Players can speak to Archon to learn about Plaguerat Apocalypse and receive a list of ingredients they need for the show. Thoughts of a Tyrant can be collected from Ihsihn, the Emporer of Fire & Demise just north of the band area. Garmir, Viscount of Tricks is southwest of the band and will drop the Vision of a Viscount. The Cravenness of a King is dropped by Nightmare, the Diamond King who can be found northeast of Plaguerat Apocalypse. Once all three ingredients are collected, players can return to the band for the last step before beating this Tiny Tina's Wonderlands's side quest.
Tiny Tina's Wonderlands: Lyre and Brimstone - Defeat Talons of Boneflesh
Adding the ingredients to the cauldron in front of Plaguerat Apocalypse will bring about the band's unfortunate demise. After witnessing the end of Plaguerat Apocalypse, players can return to Talons of Boneflesh. However, they plan on sacrificing the adventurer, so they need to be defeated in order to complete the quest. There are three band members, but Skeletons will join the fight as well. If players are at the recommended level of 15 or higher, the fight shouldn't be too difficult. After taking out the band and defeating the Skeletons, Zygaxis will scold the adventurer for not leaving a body to possess. "Lyre and Brimstone" will be completed, and "Inner Daemons" will become available.
Tiny Tina's Wonderlands: Inner Daemons - Choose Three Sins
Speaking to Zygaxis after the previous mission concludes will immediately start the "Inner Daemons" side quest. After accepting the quest, players can travel to Brighthoof and speak to Zygaxis again near the Wibblesern Well. In order for the gate to be unlocked in Tiny Tina's Wonderlands, Zygaxis needs to channel his powers through the adventurer. In order to be able to do that, players will need to complete three sins around the city. First, players will need to choose between conning three townsfolk out of money or cutting in line. The second set of sins is defacing three buildings or playing a prank, and the third choice is between killing annoying lovers or not staying off the grass. Each set of choices has one option that's clearly worse than the other. After completing three sins, players can return to the gate.
Tiny Tina's Wonderlands: Inner Daemons - Open the Gate & Defeat Leiara
Zygaxis will be waiting at the gate, and interacting with him will make him possess the adventurer. Immediately after going through the gate, there will be a few Cultists to defeat. To the left of the entrance, there's an area where the ground is wooden planks leading to a door. When facing the door, there's a hidden switch on the right side just before stepping on the planks that will unlock this secret area in Tiny Tina's Wonderlands. The stairs lead down into the Secret Catacombs where players can keep traveling deeper underground until they reach a large room with a triangular platform in the center.
Zygaxis will demand a host, but Leiara refuses and fights the adventurer instead. Leiara is level 18 and will summon level 17 enemies during the fight, so it's best to take her out as quickly as possible, then deal with her remaining minions. Once the area is cleared of enemies, players can pick up the Shadeborne Grimoire, then find a host for Zygaxis. There are three prisoners to choose from, but only the one in the center cell will work as a host for Zygaxis. After picking the right host, this side quest in Tiny Tina's Wonderlands will conclude, and players will receive their rewards.
Tiny Tina's Wonderlands is available for Xbox One, Xbox Series X/S, PlayStation 4, PlayStation 5, and PC.
