Rift Quest:Tidal Fury  

Activate the Shrine of Tides of the coast of Forlorn Fen. This gives you a 1m buff, Form of the Deep One, that changes you into a Deep One and emits a pulse that is deadly to Seacap Swarmers. Off shore you will see dozens of Seacap Swarmers just floating in clumps on the tide. Swim into them as fast as you can. You need to kill 75 of them. If you run out of time, just return to the Shrine to reacqure the buff!
