Elite Black Knight

Elite Black Knights (or Elite Black Guards) are monsters found in the basement of Black Knight's Fortress after starting the While Guthix Sleeps quest. They drop the elusive Elite black armour. They have the ability to use prayer, so it is suggested to bring at least 2 forms of attack style to kill them with. Eventually they will run out of prayer, allowing players to kill them. There is also a short break between their attacks when they switch their protection prayers. Wearing full Elite black armour or full Dagon'hai robes set will make them and others in the dungeon non-aggressive. Note that these count as black knights with regards to a player's ranking as a White Knight, with each knight counting for exactly 10 Black Knight kills. They are weaker to crush attacks than other styles, but their defence is poor in general, and the player will not miss often.

Elite Black Knight's prayer is 100% effective, unlike the Kalphite Queen's prayer which only boosts defence. Elite Black Knights will switch prayer, they do this when the sum of the hits + 1 per attack is greater than 15 for a given combat style. When they switch prayers, it will reset the damage count for the other combat style. They will run out of prayer after 20 attacks have been made against them while they are using their prayer, regardless of whether those attacks deal damage or not. Smite does not help drain their prayer, and neither does the Ancient mace or Dragon Scimitar.

An easy way to make the Elite Black Knight to run out of prayer is to attack it with fast hitting weapons. E.g. Use Bronze darts (they hit very fast, so it will make the Elite Black Knight lose its prayer faster).

Another easy tactic to use against the Elite Black Knight is the Black Salamander. It is very easy to change attack styles using only one weapon, getting around their prayer with little effort.

Full Verac Armour will penetrate their prayer but the Knights appear to have an extremely strong defence against it.

Trivia
'''
 * When first released, many players doubted the Elite Black Knights would drop Elite black armour more than once, however Mod Emilee confirmed that they would on the forums.
 * Elite Black Knights wield something appearing similar to a Saradomin sword, despite being Zamorakians. Despite this, they yell "Curses! Zamorak has abandoned me!" when they run out of prayer. It is possible that the sword is just a pun on the Saradomin Sword, for the shape of the hilt may just be a coincidence and some type of NPC only sword.
 * Sometimes Elite Black Knights would make an attempt to switch their prayer just before they die, even though they would receive less than 15 of total damage and hits. This is probably because the attacking player would have inflicted more damage if they had more health.
 * The dying knight outside the entrance to the God Wars Dungeon holds a temple knight version of the helm an Elite Black Knight wears.
