Brine rats are creatures found within the Brine Rat Cavern, which requires partial completion of Olaf's Quest and a spade to access. They require level 47 Slayer to damage.
They have relatively low
defence but can hit rather high, over 100 damage, for their combat level.
safespots exist, one of them involving the use of the light coloured skeleton in the room. Rangers and Mages may attack across these bones, trapping the monsters on the other side of the pile.
logs allows players to cook the various raw foods they drop. Alternately, there is a fire near Olaf Hradson, located outside the cavern's exit which can be used instead.
Use the Fremennik Province lodestone
Use the Fairy rings and dig the area just south of the tree
D K S Use a Ring of slaying Teleport to the Rellekka Slayer Dungeon and then run north
Use the Lyre teleport run east
Food and healing tips:
You can take raw unnoted fish and cook them using the fire next to Olaf. This way you will not have to bank as often, but you will need still need the Cooking level to do so.
Good food such as swordfish, monkfish, lobsters or even using Bones To Peaches tabs would be helpful in staying for long periods of time.
It is advisable to bring a Bunyip pouch. Not needed if you have very high combat stats though.
Do not forget to bring a spade, as you cannot use the one on your belt. If you forgot it, one spawns by Olaf.
