Knight

"You Knights [...], lead your followers in battle. Take enough devastation to feed your worm, and a little more to grow, and take the tithe of your followers. Then take another portion, as much as you dare, and use it for your own purposes. But if it is too much, your peers will kill you and take it. Then tithe the remainder to the Ascendant you serve."

- Oryx, the Taken King

Knights are a caste of formidable Hive creatures. They are elite soldiers, and typically wield Hive Boomers or a Cleaver. They can also summon a shield directly in front of them for a few seconds to block incoming fire, while regenerating a small amount of health in that time frame. On top of their formidable weaponry and defenses, Knights are even more deadly on Nightfall strikes where they acquire an Arc shield and increased effectiveness with their weapons. Some other knights, such as Blades of Crota or Urzok, the Hated, innately have Arc Absorption Shields.

Overview
Knights are promoted from the ranks of the Hive's Acolytes, chosen based on their ability to fight and feed their hungering Worm on the power of conquered foes. In Destiny 2, Knights gain a new look, appearing to sport a horned helmet, tattered cape, and glowing sigil along their faces.

Destiny
"It put up a hand and swallowed the rocket with a wall of shadow."

- Grimoire description.

Clad in armor as hard as relic iron, Knights serve as the Hive's forward heavy infantry and are their most versatile soldiers due to their superior arsenal. All Knights are capable of putting forth a Wall of Darkness, a large, black and ovular shield that completely protects them from frontal assaults and restores a set portion of their health. They are also surprisingly fast and agile given their heavy armor, capable of rolling to the sides to dodge incoming fire, and are far more durable than most other Hive troops. Additionally, when low on health, they will be sent into a berserk rage, glowing with a green aura, and rush towards the player for a high damage melee attack, while regenerating some of their lost health. The weapon they carry will affect their combat behavior.

Knights are most commonly armed with a Boomer, a handheld siege weapon capable of launching explosive Arc bolts that have devastating splash damage properties. Each bolt has a long effective range and can easily be fired one after another, forcing Guardians to fall back to another position on the battlefield while allowing the Knight to slowly corner his target. Since this dissuades any sort of close range combat, long-range weaponry with sustained damage output will fare the best against such Knights.

Alternatively, they can also be seen with a Shredder, a one-handed carbine that launches Void bolts one after another. While in the hands of an Acolyte, this weapon doesn't deal much damage, but in the hands of a Knight, it is far more accurate and has a faster rate of fire. This means that the player can get more easily suppressed by them. Knights with this weapon tend to stick to a certain distance and will try to re-position themselves if they are overtaken. Concentrated fire at any range will hold them in one place.

Knights armed with a Cleaver are some of the deadliest close-range enemies the player will encounter. They will constantly rush towards their target to land a series of powerful sword strikes, and will not stop until they kill them. Keep them at a distance to negate the use of their weapon and concentrate your fire on them to keep them stunlocked.

Destiny 2
Knights behave the same as before, but can now also carry the new crossbow-like weapons called Splinters, which shoot a fanning spread of Solar bolts. Knights with this weapon tend to move close to the enemy, to make it harder for them to dodge the fan of bolts.

In Warmind, new variants of Knights appeared, equipped with shields. Initially exclusive to the Vanquishers of the Grasp of Nokris, they would later be encountered in the hands of regular Knights across all the Broods of the Solar System.
