Map of Thalassinon's approximate spawn point. (Click image for full map.)
To spawn Thalassinon the player must talk to the "Huntmaster" in the rare game hunt party in the Phon Coast who will give details of what to do. The player must stand at the highest point in the Vaddu Strand area of the Phon Coast for ten seconds and Thalassinon will appear below on the beach.
