Brine sabre

Brine sabre is a one-handed weapon that requires an Attack level of 40 to wield. It is dropped by brine rats in the small cave accessed during Olaf's Quest. The brine sabre is slightly better than a rune scimitar.

The brine sabre has a special attack named Liquefy, that doubles the chance of hitting and adds 25% of the damage to the player's Strength, Attack and Defence. The special attack only works underwater and drains 75% of the special attack bar.

Due to its high damage output and low requirements, it is also a popular weapon for low-level players and pures.
