The basilisk sentinel is a superior variant of the basilisk knight. It has a chance of spawning after purchasing the unlock Bigger and Badder for 50 Slayer reward points from any Slayer master. Like their standard variant, a mirror shield or V's shield is required to safely engage them, as otherwise the player will take rapid damage and have their stats drained.

Along with its magic and melee attacks, it has a special attack in which it shoots a slower, pale-red coloured orb at the tile the player is currently standing on; if players do not move, this will encase them in stone, preventing players from attacking for a few seconds and displaying the message You have been entombed in stone!. This can be avoided while the orb is in flight by moving one square away, or by spam-clicking away to break free, similar to the fight against The Jormungand. When clicking away to break free, the message You feel the stone break slightly as you try to move. will be displayed. It will take four attempts to break free before succeeding, with success indicated by the message You manage to escape from the stone! . Failing to break out in time will result in a large amount of damage being inflicted, accompanied by the message The stone around you violently explodes! . While the special attack is easily avoidable, it can immediately kill players with moderate Hitpoints if they don't move in time. The special attack seems to have a cooldown of ~30 seconds beginning with the first attack, and is not guaranteed to be used immediately off cooldown.

In addition to 100% drops and tertiary drops, superior slayer monsters will always roll 3 additional items, of which only 1 roll may be from the superior unique table. The other rolls are performed on the regular counterpart's table.

Drop rates are estimated based on 348,500 samples from the Drop Rate Project, unless otherwise cited.

The average Basilisk Sentinel kill is worth 141,912.26.

The average Basilisk Sentinel kill while on a Konar task is worth 227,567.41.

• The examine message is a reference to Harry Potter and the Chamber of Secrets. The only antidote to the venom of the basilisk was the tears of a phoenix.
• The Basilisk Sentinel, along with the Dreadborn Araxyte, are the only aggressive superior slayer monsters.
