Brackish blade

The Brackish blade requires 60 attack to wield. It is dropped by 'Rum'-pumped crabs in the combat dungeon unlocked in the quest A Clockwork Syringe. It has a higher stab bonus than Korasi's sword, albeit lower strength bonus. It is a one-handed weapon. Unlike the Zamorakian spear and Korasi's sword, the Brackish blade has an aggressive stab stance, which is useful for those who do not wish to gain Defence experience. This weapon is equal in all stats to a Dragon scimitar, however the stab and slash are switched. Because Korasi's sword and Chaotic weapons are harder to obtain and have higher requirements to equip, this weapon is of great use to players fighting monsters weak to stab, such as dragons.

This weapon does not need the quest to be completed to use.

The weapon, along with the Brine sabre, also seems to do more damage against the rum drunk crabs, as the player receives a message in the chatbox that 'The Brackish Blade seems super-effective.'

The Brackish blade has a special attack that doubles the chance of hitting, and adds 2.5% of the damage to your Strength, Attack and Defence, draining 75% of the special attack meter.

Trivia

 * The "The Brackish Blade seems super-effective." might be a reference to Nintendo's Pokémon series.(but it is obviously not i am just a horny pokemon nerd)
