The Sphere Prism Key Walkthrough

This quest can be activated after reaching the Secret Facility and beginning The Research Complex Quest. You will need to make your way through to the Underground Tunnels until you reach the Test Subject Arena, past the Northern Section. 


Find The Sphere Prism Key

Engage in battle with the mutated test subjects. Remain on the upper platform. Before you approach, observe the mutant's position and deal an AoE attack if available, if not, use any ranged attack to deal to the first move. You should be able to clear the Mutated Tiger Drake first then catch the others by surprise with this approach. You will have a Mutated Bulette that will have 157 HP and a Mutated Dryad with 84 HP. Another option is to deploy a summon to approach the arena and gain a better positioning without compromising your adventurer's higher ground. Clear them to continue. You may then explore the arena and loot the corpse to obtain the Sphere Prism Key, coins, Magnificent Shield, Scroll

Return to the upper floor tunnel and if you continue to the locked gate north, you will encounter the new waypoint: Major Gate Room. This will activate the quest. Since you have already obtained the key, the first objective will be checked off. 


Use the Sphere Prism Key

You will need to progress through these tunnels until you reach the Dark Lab.Enter the Major Gate Room area to trigger short cutscene. Follow the hallway east.

Major Gate Room

Take the east hallway and use the switch. This will also complete The Security Gate if you haven't already. Past this gate is another with a switch towards the east. Use the Cylinder Prism Key here to get through.

Once this gate is open, be cautious when entering the next area. You will be met with a battle that you will need to complete down the narrow hall. You will be facing a number of Mutant Tiger Drakes and a couple of Mutated Dryad enemies. Once it is clear, follow the tunnels south and you will find your way to the Dark Lab. 


Dark Lab

Take the doors south, but be prepared for a battle against a number of large mutated enemies. This set will be fairly larger and will consist of a mutated Dire Wolf, Troll, and a Minotaur. Clear the area to continue. Loot this location, then attempt to take the doors east. Interact with the set of doors and then interact with the switch directly right of the doors. This will complete the objective, but something will be blocking the door. 


Find Another Way In


Clear this area for the secondary location quest, The Research Complex. You should be able to complete all three objectives before moving on. Scroll all the way south, there will be an undiscovered room with cells. Click the area to allow your adventurerers to find their way here. Entering this area will also progress in the giant's secondary quest, the Ugly Truth, if it has been activated. 

Loot the basket in the middle of the room to begin a quick cutscene. After the scene ends, look at the room on the other side of the wall here to the east. Click into this area and your party will find a way to climb the wall. Look south and have them push over the boulder and the box. The box will allow you to climb over to the next area further east. Entering this area will complete the current objective.
