Brine rat

Brine rats are Slayer monsters that require the partial completion of Olaf's Quest to be reached. A slayer level of 47 is required to fight the Brine rat. Brine rats have relatively low defence, but they can deal a maximum of 93 damage, relatively high for their combat level. Multiple safespots exist, one of them involving the use of the only light coloured skeleton in the room. Range and Mage users may attack across these bones, trapping the monsters on the other side of the pile. If you bring a tinderbox and logs, you can cook their meat or the raw swordfish/shark drops to last longer if you are doing slayer. Also, there is a fire (tended by Olaf Hradson) located just outside of the cavern's exit which provides an excellent location to cook either the rat meat or dropped raw fish. They also drop the brine sabre which has a special attack, Liquefy, that only works underwater.

Tips

 * Bring armour with good defence as well as a good weapon. Higher levels will not require as much food, however, they can cook the raw food drops of the Brine Rat.
 * The use of the Enhanced excalibur's special attack is suggested as it heals 200 life points and boosts the player's defence level by 15%.
 * For fast access to the Brine Rat Cavern players who have access to Fairy rings can use the code D-K-S to reach the area just south of the tree.
 * Don't forget to bring a spade.
 * If your Summoning level is high enough, it is advisable to bring a Bunyip pouch and some scrolls. Brine Rats drop plenty of raw fish with which you can heal yourself by using the Bunyip's scroll, "Swallow Whole", to keep your life points up.
 * If you take the raw unnoted fish, you can leave the cave and cook them using the fire next to Olaf. This way you will not have to bank as often.
 * Brine Rats are considered to be a very good source of money for their noted drops and the much coveted Brine Sabre. Some good food such as swordfish or monkfish would be helpful in staying for long periods of time. You can also bring bones to peaches tabs. All you have to do is pick up the bones and click on the tab for an unlimited supply of peaches.
 * The Ring of Slayer can be the fastest way to get to the brine rats.
