Let Me Solo Him: The Underpin
Defeat The Underpin in his lair on Tier ?? without any other players in your party, before the release of the next season of delves.
Let Me Solo Him: The Underpin is a solo achievement earned by defeating The Underpin in his lair inside the Demolition Dome delve without any other players in your party, rewarding the 
Delver's Gob-Trotter Schematic: Gold.
Navigate to Demolition Dome
Travel to the Demolition Dome delve and locate The Underpin at 52.38, 9.42. You must enter without any other players in your party to qualify for the achievement.
Set Brann to Healer
Set Brann to his healer specialization before engaging The Underpin — having Brann in a DPS spec leaves you without sufficient sustain and prevents him from breaking The Underpin's shell in time to stop the 25% HP heal.
Equip Recommended Delve Gear
Slot Rank 2 Impact Conversion Matrix and Rank 2 Biofuel Rocket Gear before starting. The Lootraidr utility item can provide 4% additional damage to The Underpin and is worth considering over other utility slot options.
Bind Your Interact Key
Use Blizzard's built-in Interact Keybind found in the UI options — this is required to kick bombs quickly and reliably during the fight, as manual clicking is too slow when bombs are clustered or near obstacles.
Kill Every Crony Each Wave
Eliminate every single Crony during each spawn set before they accumulate — leaving even one alive causes the encounter to spiral out of control rapidly.
Tips
Do not reset the instance between attempts, as the encounter can be reattempted without resetting.
If the achievement completes but the reward does not appear immediately, log out and back in, then check the Rostrum to claim the schematic.
