The carnage achievement Nautical Nightmares asks you to find 4 semi-rare mobs. I have found 3 of them.
Ichychul : 11708 , 3164
Aqanjale : 9864 , 2009
Heat Sink : 1141 , 3907
I simpy cannot find Nado though. I have been swimming around for hours looking. If someone gets the coords on him can you post them here? Thanks.
