Information comparing locations for Slayer tasks will be on this page

The basilisk sentinel is a superior variant of a basilisk knight. It has a chance of spawning when a basilisk knight is killed while on a slayer task, if the player has purchased the unlock Bigger and Badder for 150 Slayer reward points from any Slayer master.

Similar to their lower-level counterparts, 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 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. 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. Failing to break out in time will result in a large amount of damage being inflicted. 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.

Drops

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

Trivia

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.
