Note that these count as Black Knights with regards to a player's ranking as a White Knight, with each knight counting for exactly 12 Black Knight kills; killing them in order to ascend the player's White Knight rank instead of regular Black Knights may be preferred due to the fact that Elite Black Knights have three times the life points of regular knights but provide twelve times the ranking per kill.
Elite Black Knight's prayer is 100% effective, similar to Tormented demons and Akrisae the Doomed. Like the aforementioned monsters, Elite Black Knights will switch their overhead prayer on regular intervals when the sum of the damage dealt is greater than 1500 for a given combat style. When they switch prayers, it will reset the damage count for the other combat style. After receiving 20 attacks, their prayer points will be depleted. There is also a short break between their attacks when they switch their protection prayers. Smite or Soul Split do not help drain their prayer, and the Smash ability will not disable it.
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.
They yell "Curses, Zamorak has abandoned me!" when they run out of prayer.
Sometimes Elite Black Knights will switch their Prayer just before they die, even though they would receive less than 150 of total damage and hits. This is probably because the attacking player would have inflicted more damage if the knight had more health.
The Elite Black Knight's level was the highest combat level possible for a player to reach (before the Evolution of Combat), although the knights had 1200 life points instead of the player's max of 990.
Elite Black Knights drop their armour, unlike regular Black Knights, who only drop their swords and full helms.
Although Elite Black Knights are followers of Zamorak, they used to wield what looked distinctly like a Saradomin sword. However, they now wield black 2h swords.
Their capes look like team-12 capes but have a black base colour instead of yellow.
The second warning for bots caught by Botwatch featured normal and Elite Black Knights using the graphically updated versions of their respective armour and weapons, even before they were graphically updated.
