Welcome, this is a quick guide on how to get the Arcane Sentinel Beam in Halo Infinite. The Arcane Sentinel Beam is the upgraded version of the Sentinel Beam. You obtain the upgraded version after defeating the high value target boss “Thav ‘Sebarim, Kaidon” in the southern region of the map.
The Arcane Sentinel Beam uses Hardlight ammunition, which isn’t very common. And because the weapon deals so much damage, it empties your magazine very fast. However, you will see below that there is a neat trick with Marines that can use the weapon.
Where is the boss location to get the Arcane Sentinel Beam in Halo Infinite?
You can find the location to kill Thav Sebarim to get the Arcane Sentinel Beam in the northern area of the map. The location is close to the FOB Charlie and the Excavation Site as you can see in the map below. Thav Sebarims location is marked with a red circle.
Thav Sebarim, Kaidon
Thav Sebarim is the high value target boss (Nr 2 on the target list) that you need to kill to obtain the upgraded version of the Sentinel Beam. When you encounter him he will be in a Ghost, it is recommended to use the grapple hook to kick him out. His shield is pretty strong, but once you are through that you can kill him very easily.
Kaidon Thav ‘Sebarim was one of the leading Covenant commanders in their final strikes against earth and its colonies on Reach and Luna. He abandoned his station after the Prophets betrayed the Elites, and fled back to his homeworld of Suban to be reunited with their kin at the Keep of Malaston. As the Sangheili people descended into a vicious cycle of civil war, the kaidonjoined forces with Atriox, as the Banished did not discriminate against Sangheili warriors, so long as they were skilled. ‘Sebarim has become infamous for his actions in the Battle of Harrow, where his siege of the city of Adruvon resulted in the deaths of over 700’000 human civilians.
Where can I equip the Arcane Sentinel Beam?
After you have killed the target and its minions, you will be able to get the Arcane Sentinel Beam at any FOB. Go to one of the four weapon caches and rotate to the left to select the Arcane Sentinel Beam. And yes, you can equip the marines with this overpowered weapon in Halo Infinte.
Marines Arcane Sentinel Beam
You can equip the Marines with the Arcane Sentinel Beam and place them all in the vehicle with 6 sets. That will give you 5 Marines with Arcane Sentinel Beams that destroy pretty much anything within a blink of an eye.
Marines have endless ammunition, making the Arcane Sentinel Beam very overpowered. As an example you can see in the video below we are destroying a ship within seconds and the enemies get vaporized instantly. This makes for very fun encounters, at least for your team.
