How to Complete the Quest “Arhu’s Failed Experiment”

There are multiple stages to completing “Arhu’s Failed Experiment”, so below is a guide detailing each of them in the order you need to complete them.

Journey to the Row Tunnel

Speaking Arhu or Visco, you will discover the location of a cave with the SparkMaster 5,000. Follow your quest marker out of Cyseal and to the Rank Tunnel. Upon entering, you will encounter a robot named SparkMaster 5,000, which you must defeat to progress. Visco will also approach you and three soldiers will help you fight the robot.

(Optional) Detonate the SparkMaster 5,000

The easiest way to defeat the SparkMaster 5,000 is to using the Spark Master 5,000 Universal Controller that Arhu gives you if you tell him about the failed experiment. If you have it, you can use it to immediately cause the SparkMaster 5000 to self-destruct.

You must use the (Happy, Happy, Happy) option followed by the (Angry, Angry, Sleepy) option when interacting with the controller for it to explode. If you choose to detonate the SparkMaster 5,000, you will not gain any Robot XP.

If you want to gain XP with the SparkMaster 5,000, you need to defeat it in battle. This will also be the only way to complete “Arhu’s Failed Experiment” if you haven’t collected Arhu’s Controller.

Defeat the SparkMaster 5,000

Visco’s men will aid you in the fight against the SparkMaster 5,000, and you’ll gain more XP for each of the men alive after the fight, including three in total. If every soldier dies during combat, then “Arhu’s failed experiment” the mission will fail.

The combat is quite easy if you play in classic mode, because the Spark Master 5,000 has a weakness at flash. However, lightning will also charge the robot. Once the robot is fully charged, you need to activate the Three nearby levers so that the SparkMaster 5000 uses the load. The SparkMaster 5,000 also primarily uses lightning attacks, so it’s good to have some defense against that type of magic.

You will also have to deal with of them Undead Magi, which will fire magic attacks at you during their turn. Mages will also charge the SparkMaster 5,000 during their turn, and if you don’t activate all three levers in the room, the robot will use its Ultrabolt attack. As such, prioritize defeating undead mages before attacking the SparkMaster 5,000.

If you play Divinity: Original Sin in Tactician Mode or Honor Mode, there will be some differences. First, the SparkMaster 5000 Fire a barrage of missile which inflict fire damage. When the robot launches this attack, the missiles will wait one turn until they reach their target. You should bring some form of fire protection to defend against missiles.

However, the main threat on Tactician or Honor difficulty are the two undead mages who will now sit behind the SparkMaster 5,000, so they are harder to attack. Since the undead mages will now be in the back, you need to prioritize defeating them even more urgently.

After defeating both the SparkMaster 5,000 and the Undead Mages, you will earn up to 1575 XP and can travel to Cyseal to complete the quest “Arhu’s Failed Experiment”.

Talk to slimy

After defeating the SparkMaster 5,000 with at least one of Visco’s men surviving the battle, you can travel to Legion HQ in Cyseal and enter the prison area, where you will encounter Viscous. To tell about Viscous of your victory, and the quest “Arhu’s Failed Experiment” will complete, earning you 1,800 XP. You can also convince Viscous to open the nearby treasure room if you win a rock-paper-scissors mini-game against him.
