Kruutiks, Reefbane

Kruutiks, Reefbane was a powerful Scorn Raider that featured as one of the final bosses of the Astral Alignment activity, in which they attempt to secure the Blind Well for Xivu Arath, God of War. They later took part in the assault on the ritual to remove the Worm of Savathûn, but they were defeated for the final time by the Guardians.

Astral Alignment
Kruutiks is one of the two, weekly-rotating final bosses encountered within the Astral Alignment activity. They bar the Fireteam from completing the realignment of the Ley Lines to assist the forces of Xivu Arath in taking the Blind Well.

Kruutiks appears in the last encounter of the activity when the realignment is nearly complete, spawning alongside various Scorn reinforcements. They come armed with a long-ranged Scorn Crossbow, to hit their enemies from far away. When a player gets in too close, boss can charge towards them to swing at their enemy, although they lack ground stomp attack typical of most Ultra. The Raider also possess an ability of Pirrha, the Rifleman: being able to summon several holographic decoys to confuse their enemies, whilst also providing extra backup for themselves.

The boss's is divided into three sections. Whenever a third of their health is depleted, Kruutiks will attempt to teleport to another location near the Blind Well and deploy more decoys, along with a harvested Servitor. This device will emit several clouds of Ether, which will heal the boss significantly if you do not shot them down before they reach them. They will eventually summon in another Servitor when two thirds of his health is depleted. Once the Reefbane has been neutralized, the activity will be completed.

Exorcism
Kruutiks appears alongside Kholks, Taken of Xivu Arath, as a boss in the Exorcism Mission. After Mara Sov and her Techeuns have begun the ritual and Saint-14 has raised his Ward of Dawn, both of Xivu Arath's minions will appear on the two overlooking points in the far corners of the arena. Multiple Taken Blights will materialize throughout the room, before the Raider will teleport down to commence the battle. Kruutiks uses the same abilities and tactics they do in Astral Alignment: using a Crossbow to pick off his targets from long distances while utilizing decoys to for increased firepower. The boss will also be assisted by numerous Hive forces during the fight, including Barrier Knight Champions.

After half of the Reefbane's health has been depleted, Kholks will come down to assist it's ally in destroying the fireteam and the ritual. However, you are not required to completely finish the two off. You need only whittle them down until they have a quarter of their health left, at which point they will teleport back to their original positions, befor the final boss emerges from the Blight: Kelgorath, Risen from Bones.
