Seastone

The Seastone is an item used in the crafting of "Ocean's Blessing" mark which is used to tame the Gilded Benthic. The best place to obtain the Seastone is from "King Soriphen" who is located at Rainbow Reef in the Sea of Hakanas. The best way to farm for Seastone is to use a flying mount to land behind and under the building below the King, and to kite him to you while avoiding AOE attacks that would attract his two healers. The king has a high drop rate for the Seastone, but can also drop "Ocean Soul Fragment" which are also used in creating "Ocean's Call".
