Brine rat safespot

Location of the brine rat safespot.
(Southeast corner)

Brine rats are Slayer monsters that can only be fought after the partial completion of Olaf's Quest. They are notable for being the only monsters to drop the Brine sabre. A Slayer level of 47 is required to fight a brine rat, and a spade is required to access the cave. The brine rats are relatively weak, but it is recommended to bring food if you have less than 70 Defence. Olaf has an infinite fire located beside him, and the unnoted raw swordfish drops can be collected and cooked on the fire, just outside the brine rat cave. Brine rats can also be killed as an alternative for a rat slayer assignment provided the player has 47 Slayer.

Rangers and mages may attack behind the skeletons and bones lying throughout the room to safespot the rats. The best location being behind the bones in the north-west corner.

Bringing a tinderbox and a couple of logs may be advisable if staying there for a while due to their raw swordfish/shark drop.

A Dwarf multicannon is usable in the Brine Rat Cavern.
