When blown, it will provide a 'Conch!' buff that gives 25% increase in the experience from skilling activities in the event or one extra token per kill and 25% extra experience from killing the Skulls pirates. The buff lasts for three minutes. The shell is consumed upon blowing. This buff does stack with any bonus experience you have, and only one conch shell buff can be active at a time. The 'Conch!' buff did not increase the experience given from using tools in the Boat to the Arc event. File:Blowing Conch Shell (Port Sarim Invasion).gif
