Pick up the quests Supervisor Fizsprocket & The Venture Co from Morin Cloudstalker, both quests can be done together.
You may need to complete The Ravaged Caravan first. Also picked up from Morin Cloudstalker.
Head to the cave entrance along the hills Northeast of Bloodhoof Village. Inside and outside the cave, you will find Venture Company workers and Supervisors ranging from level 7-10.
Don't waste your time killing the venture company mobs outside of the cave. Instead, make your way inside the cave while eliminating any mobs along the way. This will help you make progress on The Venture Company.
Follow the cave wall to your right and you will find Supervisor Fizsprocket standing near the back of this chamber. He is level 12 and he doesn't hit too hard, but what can make this fight difficult are the surrounding enemies. It can be difficult to fight him alone without pulling aggro from other enemies.
Hardcore difficulty for the Venture Co is moderate due to the enemies running away at low health. However, this particular quest can be completed by killing enemies outside of the cave. Supervisor Fizsprocket may be difficult for Hardcore players because he is inside the cave, and as they say in Hardcore, "If you can't see sky, you're gonna die." Fortunately, he is not very deep inside the cave.
After defeating Supervisor Fizsprocket, loot his body for make your way back out of the cave while cleaning up any remaining Venture Company Workers and Supervisors along the way.
Return to Morin Cloudstalker for your reward.
